Description STM32H743xI
14/231 DS12110 Rev 5
STM32H743xI devices operate in the –40 to +85 °C temperature range from a 1.62 to 3.6 V
power supply. The supply voltage can drop down to 1.62 V by using an external power
supervisor (see Section 3.5.2: Power supply supervisor) and connecting the PDR_ON pin to
VSS. Otherwise the supply voltage must stay above 1.71 V with the embedded power
voltage detector enabled.
Dedicated supply inputs for USB (OTG_FS and OTG_HS) are available on all packages
except LQFP100 to allow a greater power supply choice.
A comprehensive set of power-saving modes allows the design of low-power applications.
STM32H743xI devices are offered in 8 packages ranging from 100 pins to 240 pins/balls.
The set of included peripherals changes with the device chosen.
These features make STM32H743xI microcontrollers suitable for a wide range of
applications:
Motor drive and application control
Medical equipment
Industrial applications: PLC, inverters, circuit breakers
Printers, and scanners
Alarm systems, video intercom, and HVAC
Home audio appliances
Mobile applications, Internet of Things
Wearable devices: smart watches.
Figure 1 shows the general block diagram of the device family.

1. The SPI1, SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio
mode.
2. Since the LQFP100 package does not feature the PDR_ON pin (tied internally to VDD), the minimum VDD value for this
package is 1.71 V.
3. VDD/VDDA can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor)
and connecting PDR_ON pin to VSS. Otherwise the supply voltage must stay above 1.71 V with the embedded power
voltage detector enabled.
4. The product junction temperature must be kept within the –40 to +125 °C temperature range.
5. This package is under development. Please contact STMicroelectronics for details.

18/231 DS12110 Rev 5
3 Functional overview
3.1 Arm® Cortex®-M7 with FPU
The Arm® Cortex®-M7 with double-precision FPU processor is the latest generation of Arm
processors for embedded systems. It was developed to provide a low-cost platform that
meets the needs of MCU implementation, with a reduced pin count and optimized power
consumption, while delivering outstanding computational performance and low interrupt
latency.
The Cortex®-M7 processor is a highly efficient high-performance featuring:
Six-stage dual-issue pipeline
Dynamic branch prediction
Harvard architecture with L1 caches (16 Kbytes of I-cache and 16 Kbytes of D-cache)
64-bit AXI interface
64-bit ITCM interface
2x32-bit DTCM interfaces
The following memory interfaces are supported:
Separate Instruction and Data buses (Harvard Architecture) to optimize CPU latency
Tightly Coupled Memory (TCM) interface designed for fast and deterministic SRAM
accesses
AXI Bus interface to optimize Burst transfers
Dedicated low-latency AHB-Lite peripheral bus (AHBP) to connect to peripherals.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
It also supports single and double precision FPU (floating point unit) speeds up software
development by using metalanguage development tools, while avoiding saturation.
Figure 1 shows the general block diagram of the STM32H743xI family.
Note: Cortex®-M7 with FPU core is binary compatible with the Cortex®-M4 core.
3.2 Memory protection unit (MPU)
The memory protection unit (MPU) manages the CPU access rights and the attributes of the
system resources. It has to be programmed and enabled before use. Its main purposes are
to prevent an untrusted user program to accidentally corrupt data used by the OS and/or by
a privileged task, but also to protect data processes or read-protect memory regions.
The MPU defines access rules for privileged accesses and user program accesses. It
allows defining up to 16 protected regions that can in turn be divided into up to 8
independent subregions, where region address, size, and attributes can be configured. The
protection area ranges from 32 bytes to 4 Gbytes of addressable memory.
When an unauthorized access is performed, a memory management exception is
generated.

3.3 Memories
3.3.1 Embedded Flash memory
The STM32H743xI devices embed up to 2 Mbytes of Flash memory that can be used for
storing programs and data.
The Flash memory is organized as 266-bit Flash words memory that can be used for storing
both code and data constants. Each word consists of:
One Flash word (8 words, 32 bytes or 256 bits)
10 ECC bits.
The Flash memory is divided into two independent banks. Each bank is organized as
follows:
•A 1-Mbyte user Flash memory block containing eight user sectors of
128 Kbytes(4 K Flash words)
•128 Kbytes of System Flash memory from which the device can boot
2 Kbytes (64 Flash words) of user option bytes for user configuration
3.3.2 Embedded SRAM
All devices feature:
512 Kbytes of AXI-SRAM mapped onto AXI bus on D1 domain.
SRAM1 mapped on D2 domain: 128 Kbytes
SRAM2 mapped on D2 domain: 128 Kbytes
SRAM3 mapped on D2 domain: 32 Kbytes
SRAM4 mapped on D3 domain: 64 Kbytes
4 Kbytes of backup SRAM
The content of this area is protected against possible unwanted write accesses,
and is retained in Standby or VBAT mode.
RAM mapped to TCM interface (ITCM and DTCM):
Both ITCM and DTCM RAMs are 0 wait state memories. either They can be accessed
either from the CPU or the MDMA (even in Sleep mode) through a specific AHB slave
of the CPU(AHBP):
– 64 Kbytes of ITCM-RAM (instruction RAM)
This RAM is connected to ITCM 64-bit interface designed for execution of critical
real-times routines by the CPU.
– 128 Kbytes of DTCM-RAM (2x 64-Kbyte DTCM-RAMs on 2x32-bit DTCM ports)
The DTCM-RAM could be used for critical real-time data, such as interrupt service
routines or stack/heap memory. Both DTCM-RAMs can be used in parallel (for
load/store operations) thanks to the Cortex®-M7 dual issue capability.
The MDMA can be used to load code or data in ITCM or DTCM RAMs.
Functional overview STM32H743xI
20/231 DS12110 Rev 5
Error code correction (ECC)
Over the product lifetime, and/or due to external events such as radiations, invalid bits in
memories may occur. They can be detected and corrected by ECC. This is an expected
behavior that has to be managed at final-application software level in order to ensure data
integrity through ECC algorithms implementation.
SRAM data are protected by ECC:
7 ECC bits are added per 32-bit word.
8 ECC bits are added per 64-bit word for AXI-SRAM and ITCM-RAM.
The ECC mechanism is based on the SECDED algorithm. It supports single-error correction
and double-error detection.
3.4 Boot modes
At startup, the boot memory space is selected by the BOOT pin and BOOT_ADDx option
bytes, allowing to program any boot memory address from 0x0000 0000 to 0x3FFF FFFF
which includes:
All Flash address space
All RAM address space: ITCM, DTCM RAMs and SRAMs
The System memory bootloader
The boot loader is located in non-user System memory. It is used to reprogram the Flash
memory through a serial interface (USART, I2C, SPI, USB-DFU). Refer to STM32
microcontroller System memory Boot mode application note (AN2606) for details.
3.5 Power supply management
3.5.1 Power supply scheme
STM32H743xI power supply voltages are the following:
VDD = 1.62 to 3.6 V: external power supply for I/Os, provided externally through VDD
pins.
VDDLDO = 1.62 to 3.6 V: supply voltage for the internal regulator supplying VCORE
VDDA = 1.62 to 3.6 V: external analog power supplies for ADC, DAC, COMP and
OPAMP.
VDD33USB and VDD50USB:
VDD50USB can be supplied through the USB cable to generate the VDD33USB via the
USB internal regulator. This allows supporting a VDD supply different from 3.3 V.
The USB regulator can be bypassed to supply directly VDD33USB if VDD = 3.3 V.
VBAT = 1.2 to 3.6 V: power supply for the VSW domain when VDD is not present.
VCAP: VCORE supply voltage, which values depend on voltage scaling (0.7 V, 0.9 V,
1.0 V, 1.1 V or 1.2 V). They are configured through VOS bits in PWR_D3CR register.
DS12110 Rev 5 21/231
STM32H743xI Functional overview
47
The VCORE domain is split into the following power domains that can be independently
switch off.
– D1 domain containing some peripherals and the Cortex®-M7 core.
– D2 domain containing a large part of the peripherals.
– D3 domain containing some peripherals and the system control.
During power-up and power-down phases, the following power sequence requirements
must be respected (see Figure 2):
When VDD is below 1 V, other power supplies (VDDA, VDD33USB, VDD50USB) must
remain below VDD + 300 mV.
When VDD is above 1 V, all power supplies are independent.
During the power-down phase, VDD can temporarily become lower than other supplies only
if the energy provided to the microcontroller remains below 1 mJ. This allows external
decoupling capacitors to be discharged with different time constants during the power-down
transient phase.

3.5.2 Power supply supervisor
The devices have an integrated power-on reset (POR)/ power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry:
Power-on reset (POR)
The POR supervisor monitors VDD power supply and compares it to a fixed threshold.
The devices remain in Reset mode when VDD is below this threshold,
Power-down reset (PDR)
The PDR supervisor monitors VDD power supply. A reset is generated when VDD drops
below a fixed threshold.
The PDR supervisor can be enabled/disabled through PDR_ON pin.
Brownout reset (BOR)
The BOR supervisor monitors VDD power supply. Three BOR thresholds (from 2.1 to
2.7 V) can be configured through option bytes. A reset is generated when VDD drops
below this threshold.
3.5.3 Voltage regulator
The same voltage regulator supplies the 3 power domains (D1, D2 and D3). D1 and D2 can
be independently switched off.
Voltage regulator output can be adjusted according to application needs through 5 power
supply levels:
Run mode (VOS1 to VOS3)
– Scale 1: high performance
– Scale 2: medium performance and consumption
– Scale 3: optimized performance and low-power consumption
Stop mode (SVOS3 to SVOS5)
– Scale 3: peripheral with wakeup from Stop mode capabilities (UART, SPI, I2C,
LPTIM) are operational
– Scale 4 and 5 where the peripheral with wakeup from Stop mode is disabled
The peripheral functionality is disabled but wakeup from Stop mode is possible
through GPIO or asynchronous interrupt.
DS12110 Rev 5 23/231
STM32H743xI Functional overview

3.6 Low-power strategy
There are several ways to reduce power consumption on STM32H743xI:
Decrease dynamic power consumption by slowing down the system clocks even in
Run mode and individually clock gating the peripherals that are not used.
Save power consumption when the CPU is idle, by selecting among the available low-
power mode according to the user application needs. This allows achieving the best
compromise between short startup time, low-power consumption, as well as available
wakeup sources.
The devices feature several low-power modes:
CSleep (CPU clock stopped)
CStop (CPU sub-system clock stopped)
DStop (Domain bus matrix clock stopped)
Stop (System clock stopped)
DStandby (Domain powered down)
Standby (System powered down)
CSleep and CStop low-power modes are entered by the MCU when executing the WFI
(Wait for Interrupt) or WFE (Wait for Event) instructions, or when the SLEEPONEXIT bit of
the Cortex®-Mx core is set after returning from an interrupt service routine.
A domain can enter low-power mode (DStop or DStandby) when the processor, its
subsystem and the peripherals allocated in the domain enter low-power mode.
If part of the domain is not in low-power mode, the domain remains in the current mode.
Finally the system can enter Stop or Standby when all EXTI wakeup sources are cleared
and the power domains are in DStop or DStandby mode.

Functional overview STM32H743xI
24/231 DS12110 Rev 5
3.7 Reset and clock controller (RCC)
The clock and reset controller is located in D3 domain. The RCC manages the generation of
all the clocks, as well as the clock gating and the control of the system and peripheral
resets. It provides a high flexibility in the choice of clock sources and allows to apply clock
ratios to improve the power consumption. In addition, on some communication peripherals
that are capable to work with two different clock domains (either a bus interface clock or a
kernel peripheral clock), the system frequency can be changed without modifying the
baudrate.
3.7.1 Clock management
The devices embed four internal oscillators, two oscillators with external crystal or
resonator, two internal oscillators with fast startup time and three PLLs.
The RCC receives the following clock source inputs:
Internal oscillators:
–64 MHz HSI clock
– 48 MHz RC oscillator
– 4 MHz CSI clock
– 32 kHz LSI clock
External oscillators:
– 4-48 MHz HSE clock
– 32.768 kHz LSE clock
The RCC provides three PLLs: one for system clock, two for kernel clocks.
The system starts on the HSI clock. The user application can then select the clock
configuration.
3.7.2 System reset sources
Power-on reset initializes all registers while system reset reinitializes the system except for
the debug, part of the RCC and power controller status registers, as well as the backup
power domain.
A system reset is generated in the following cases:
Power-on reset (pwr_por_rst)
Brownout reset
Low level on NRST pin (external reset)
Window watchdog
Independent watchdog
Software reset
Low-power mode security reset
Exit from Standby

3.8 General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
After reset, all GPIOs (except debug pins) are in Analog mode to reduce power
consumption (refer to GPIOs register reset values in the device reference manual).
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
3.9 Bus-interconnect matrix
The devices feature an AXI bus matrix, two AHB bus matrices and bus bridges that allow
interconnecting bus masters with bus slaves (see Figure 3).

3.10 DMA controllers
. The devices feature four DMA instances to unload CPU activity:
A master direct memory access (MDMA)
The MDMA is a high-speed DMA controller, which is in charge of all types of memory
transfers (peripheral to memory, memory to memory, memory to peripheral), without
any CPU action. It features a master AXI interface and a dedicated AHB interface to
access Cortex®-M7 TCM memories.
The MDMA is located in D1 domain. It is able to interface with the other DMA
controllers located in D2 domain to extend the standard DMA capabilities, or can
manage peripheral DMA requests directly.
Each of the 16 channels can perform single block transfers, repeated block transfers
and linked list transfers.
Two dual-port DMAs (DMA1, DMA2) located in D2 domain, with FIFO and request
router capabilities.
One basic DMA (BDMA) located in D3 domain, with request router capabilities.
The DMA request router could be considered as an extension of the DMA controller. It
routes the DMA peripheral requests to the DMA controller itself. This allowing managing the
DMA requests with a high flexibility, maximizing the number of DMA requests that run
concurrently, as well as generating DMA requests from peripheral output trigger or DMA
event.
3.11 Chrom-ART Accelerator™ (DMA2D)
The Chrom-Art Accelerator™ (DMA2D) is a graphical accelerator which offers advanced bit
blitting, row data copy and pixel format conversion. It supports the following functions:
Rectangle filling with a fixed color
Rectangle copy
Rectangle copy with pixel format conversion
Rectangle composition with blending and pixel format conversion
Various image format coding are supported, from indirect 4bpp color mode up to 32bpp
direct color. It embeds dedicated memory to store color lookup tables. The DMA2D also
supports block based YCbCr to handle JPEG decoder output.
An interrupt can be generated when an operation is complete or at a programmed
watermark.
All the operations are fully automatized and are running independently from the CPU or the
DMAs.
Functional overview STM32H743xI
28/231 DS12110 Rev 5
3.12 Nested vectored interrupt controller (NVIC)
The devices embed a nested vectored interrupt controller which is able to manage 16
priority levels, and handle up to 150 maskable interrupt channels plus the 16 interrupt lines
of the Cortex®-M7 with FPU core.
Closely coupled NVIC gives low-latency interrupt processing
Interrupt entry vector table address passed directly to the core
Allows early processing of interrupts
Processing of late arriving, higher-priority interrupts
Support tail chaining
Processor context automatically saved on interrupt entry, and restored on interrupt exit
with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
3.13 Extended interrupt and event controller (EXTI)
The EXTI controller performs interrupt and event management. In addition, it can wake up
the processor, power domains and/or D3 domain from Stop mode.
The EXTI handles up to 89 independent event/interrupt lines split as 28 configurable events
and 61 direct events .
Configurable events have dedicated pending flags, active edge selection, and software
trigger capable.
Direct events provide interrupts or events from peripherals having a status flag.
3.14 Cyclic redundancy check calculation unit (CRC)
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a
programmable polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at link-
time and stored at a given memory location.

3.15 Flexible memory controller (FMC)
The FMC controller main features are the following:
Interface with static-memory mapped devices including:
– Static random access memory (SRAM)
– NOR Flash memory/OneNAND Flash memory
– PSRAM (4 memory banks)
– NAND Flash memory with ECC hardware to check up to 8 Kbytes of data
Interface with synchronous DRAM (SDRAM/Mobile LPSDR SDRAM) memories
8-,16-,32-bit data bus width
Independent Chip Select control for each memory bank
Independent configuration for each memory bank
Write FIFO
Read FIFO for SDRAM controller
The maximum FMC_CLK/FMC_SDCLK frequency for synchronous accesses is the
FMC kernel clock divided by 2.
3.16 Quad-SPI memory interface (QUADSPI)
All devices embed a Quad-SPI memory interface, which is a specialized communication
interface targeting Single, Dual or Quad-SPI Flash memories. It supports both single and
double datarate operations.
It can operate in any of the following modes:
Direct mode through registers
External Flash status register polling mode
Memory mapped mode.
Up to 256 Mbytes of external Flash memory can be mapped, and 8-, 16- and 32-bit data
accesses are supported as well as code execution.
The opcode and the frame format are fully programmable.
3.17 Analog-to-digital converters (ADCs)
The STM32H743xI devices embed three analog-to-digital converters, which resolution can
be configured to 16, 14, 12, 10 or 8 bits. The sampling rates are respectively 3.6 MSPS,
4 MSPS, 4.5 MSPS, 5 MSPS and 6 MSPS when the ADC frequency (fADC) is 36 MHz.
Each ADC shares up to 20 external channels, performing conversions in the Single-shot or
Scan mode. In Scan mode, automatic conversion is performed on a selected group of
analog inputs.
Additional logic functions embedded in the ADC interface allow:
Simultaneous sample and hold
Interleaved sample and hold
The ADC can be served by the DMA controller, thus allowing to automatically transfer ADC
converted values to a destination location without any software action.
Functional overview STM32H743xI
30/231 DS12110 Rev 5
In addition, an analog watchdog feature can accurately monitor the converted voltage of
one, some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds.
To synchronize A/D conversion and timers, the ADCs could be triggered by any of TIM1,
TIM2, TIM3, TIM4, TIM6, TIM8, TIM15, HRTIM1 and LPTIM1 timer.
3.18 Temperature sensor
STM32H743xI devices embed a temperature sensor that generates a voltage (VTS) that
varies linearly with the temperature. This temperature sensor is internally connected to
ADC3_IN18. The conversion range is between 1.7 V and 3.6 V. It can measure the device
junction temperature ranging from −40 to +125 °C.
The temperature sensor have a good linearity, but it has to be calibrated to obtain a good
overall accuracy of the temperature measurement. As the temperature sensor offset varies
from chip to chip due to process variation, the uncalibrated internal temperature sensor is
suitable for applications that detect temperature changes only. To improve the accuracy of
the temperature sensor measurement, each device is individually factory-calibrated by ST.
The temperature sensor factory calibration data are stored by ST in the System memory
area, which is accessible in Read-only mode.
3.19 VBAT operation
The VBAT power domain contains the RTC, the backup registers and the backup SRAM.
To optimize battery duration, this power domain is supplied by VDD when available or by the
voltage applied on VBAT pin (when VDD supply is not present). VBAT power is switched
when the PDR detects that VDD dropped below the PDR level.
The voltage on the VBAT pin could be provided by an external battery, a supercapacitor or
directly by VDD, in which case, the VDD mode is not functional.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When PDR_ON pin is connected to VSS (Internal Reset OFF), the VBAT functionality is no
more available and VBAT pin should be connected to VDD.

3.28.1 High-resolution timer (HRTIM1)
The high-resolution timer (HRTIM1) allows generating digital signals with high-accuracy
timings, such as PWM or phase-shifted pulses.
It consists of 6 timers, 1 master and 5 slaves, totaling 10 high-resolution outputs, which can
be coupled by pairs for deadtime insertion. It also features 5 fault inputs for protection
purposes and 10 inputs to handle external events such as current limitation, zero voltage or
zero current switching.
The HRTIM1 timer is made of a digital kernel clocked at 400 MHz The high-resolution is
available on the 10 outputs in all operating modes: variable duty cycle, variable frequency,
and constant ON time.
The slave timers can be combined to control multiswitch complex converters or operate
independently to manage multiple independent converters.
The waveforms are defined by a combination of user-defined timings and external events
such as analog or digital feedbacks signals.
HRTIM1 timer includes options for blanking and filtering out spurious events or faults. It also
offers specific modes and features to offload the CPU: DMA requests, Burst mode
controller, Push-pull and Resonant mode.
It supports many topologies including LLC, Full bridge phase shifted, buck or boost
converters, either in voltage or current mode, as well as lighting application (fluorescent or
LED). It can also be used as a general purpose timer, for instance to achieve high-resolution
PWM-emulated DAC.

3.28.2 Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
Input capture
Output compare
PWM generation (Edge- or Center-aligned modes)
One-pulse mode output
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
The advanced-control timer can work together with the TIMx timers via the Timer Link
feature for synchronization or event chaining.
TIM1 and TIM8 support independent DMA request generation.
3.28.3 General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32H743xI
devices (see Table 5 for differences).
TIM2, TIM3, TIM4, TIM5
The devices include 4 full-featured general-purpose timers: TIM2, TIM3, TIM4 and
TIM5. TIM2 and TIM5 are based on a 32-bit auto-reload up/downcounter and a 16-bit
prescaler while TIM3 and TIM4 are based on a 16-bit auto-reload up/downcounter and
a 16-bit prescaler. All timers feature 4 independent channels for input capture/output
compare, PWM or One-pulse mode output. This gives up to 16 input capture/output
compare/PWMs on the largest packages.
TIM2, TIM3, TIM4 and TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the
Timer Link feature for synchronization or event chaining.
Any of these general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are
capable of handling quadrature (incremental) encoder signals and the digital outputs
from 1 to 4 hall-effect sensors.
TIM12, TIM13, TIM14, TIM15, TIM16, TIM17
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM13, TIM14, TIM16 and TIM17 feature one independent channel, whereas TIM12
and TIM15 have two independent channels for input capture/output compare, PWM or
One-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5
full-featured general-purpose timers or used as simple timebases.
Functional overview STM32H743xI
38/231 DS12110 Rev 5
3.28.4 Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger and waveform generation. They can also be
used as a generic 16-bit time base.
TIM6 and TIM7 support independent DMA request generation.
3.28.5 Low-power timers (LPTIM1, LPTIM2, LPTIM3, LPTIM4, LPTIM5)
The low-power timers have an independent clock and is running also in Stop mode if it is
clocked by LSE, LSI or an external clock. It is able to wakeup the devices from Stop mode.
This low-power timer supports the following features:
16-bit up counter with 16-bit autoreload register
16-bit compare register
Configurable output: pulse, PWM
Continuous / One-shot mode
Selectable software / hardware input trigger
Selectable clock source:
Internal clock source: LSE, LSI, HSI or APB clock
External clock source over LPTIM input (working even with no internal clock source
running, used by the Pulse Counter Application)
Programmable digital glitch filter
Encoder mode
3.28.6 Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
3.28.7 Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
Debug mode.
3.28.8 SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
downcounter. It features:
A 24-bit downcounter
Autoreload capability
Maskable system interrupt generation when the counter reaches 0
Programmable clock source.

3.29 Real-time clock (RTC), backup SRAM and backup registers
The RTC is an independent BCD timer/counter. It supports the following features:
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
Automatic correction for 28, 29 (leap year), 30, and 31 days of the month.
Two programmable alarms.
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock.
Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision.
Digital calibration circuit with 0.95 ppm resolution, to compensate for quartz crystal
inaccuracy.
Three anti-tamper detection pins with programmable filter.
Timestamp feature which can be used to save the calendar content. This function can
be triggered by an event on the timestamp pin, or by a tamper event, or by a switch to
VBAT mode.
17-bit auto-reload wakeup timer (WUT) for periodic events with programmable
resolution and period.
The RTC and the 32 backup registers are supplied through a switch that takes power either
from the VDD supply when present or from the VBAT pin.
The backup registers are 32-bit registers used to store 128 bytes of user application data
when VDD power is not present. They are not reset by a system or power reset, or when the
device wakes up from Standby mode.
The RTC clock sources can be:
A 32.768 kHz external crystal (LSE)
An external resonator or oscillator (LSE)
The internal low-power RC oscillator (LSI, with typical frequency of 32 kHz)
The high-speed external clock (HSE) divided by 32.
The RTC is functional in VBAT mode and in all low-power modes when it is clocked by the
LSE. When clocked by the LSI, the RTC is not functional in VBAT mode, but is functional in
all low-power modes.
All RTC events (Alarm, Wakeup Timer, Timestamp or Tamper) can generate an interrupt and
wakeup the device from the low-power modes.

The LPUART has a clock domain independent from the CPU clock, and can wakeup the
system from Stop mode. The wakeup from Stop mode are programmable and can be done
on:
Start bit detection
Any received data frame
A specific programmed data frame

while having an extremely low energy consumption. Higher speed clock can be used to
reach higher baudrates.
LPUART interface can be served by the DMA controller.
3.33 Serial peripheral interface (SPI)/inter- integrated sound
interfaces (I2S)
The devices feature up to six SPIs (SPI2S1, SPI2S2, SPI2S3, SPI4, SPI5 and SPI6) that
allow communicating up to 150 Mbits/s in Master and Slave modes, in Half-duplex, Full-
duplex and Simplex modes. The 3-bit prescaler gives 8 master mode frequencies and the
frame is configurable from 4 to 16 bits. All SPI interfaces support NSS pulse mode, TI mode,
Hardware CRC calculation and 8x 8-bit embedded Rx and Tx FIFOs with DMA capability.
Three standard I2S interfaces (multiplexed with SPI1, SPI2 and SPI3) are available. They
can be operated in Master or Slave mode, in Simplex communication modes, and can be
configured to operate with a 16-/32-bit resolution as an input or output channel. Audio
sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of the
I2S interfaces is/are configured in Master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency. All I2S interfaces support 16x 8-
bit embedded Rx and Tx FIFOs with DMA capability.
3.34 Serial audio interfaces (SAI)
The devices embed 4 SAIs (SAI1, SAI2, SAI3 and SAI4) that allow designing many stereo
or mono audio protocols such as I2S, LSB or MSB-justified, PCM/DSP, TDM or AC’97. An
SPDIF output is available when the audio block is configured as a transmitter. To bring this
level of flexibility and reconfigurability, the SAI contains two independent audio sub-blocks.
Each block has it own clock generator and I/O line controller.
Audio sampling frequencies up to 192 kHz are supported.
In addition, up to 8 microphones can be supported thanks to an embedded PDM interface.
The SAI can work in master or slave configuration. The audio sub-blocks can be either
receiver or transmitter and can work synchronously or asynchronously (with respect to the
other one). The SAI can be connected with other SAIs to work synchronously.

Specification Version 4.51 in three different databus modes: 1 bit (default), 4 bits and 8 bits.
Both interfaces support the SD memory card specifications version 4.1. and the SDIO card
specification version 4.0. in two different databus modes: 1 bit (default) and 4 bits.
Each SDMMC host interface supports only one SD/SDIO/MMC card at any one time and a
stack of MMC Version 4.51 or previous.
The SDMMC host interface embeds a dedicated DMA controller allowing high-speed
transfers between the interface and the SRAM.
3.39 Controller area network (FDCAN1, FDCAN2)
The controller area network (CAN) subsystem consists of two CAN modules, a shared
message RAM memory and a clock calibration unit.
Both CAN modules (FDCAN1 and FDCAN2) are compliant with ISO 11898-1 (CAN protocol
specification version 2.0 part A, B) and CAN FD protocol specification version 1.0.
FDCAN1 supports time triggered CAN (TTCAN) specified in ISO 11898-4, including event
synchronized time-triggered communication, global system time, and clock drift
compensation. The FDCAN1 contains additional registers, specific to the time triggered
feature. The CAN FD option can be used together with event-triggered and time-triggered
CAN communication.
A 10-Kbyte message RAM memory implements filters, receive FIFOs, receive buffers,
transmit event FIFOs, transmit buffers (and triggers for TTCAN). This message RAM is
shared between the two FDCAN1 and FDCAN2 modules.
The common clock calibration unit is optional. It can be used to generate a calibrated clock
for both FDCAN1 and FDCAN2 from the HSI internal RC oscillator and the PLL, by
evaluating CAN messages received by the FDCAN1.

3.40 Universal serial bus on-the-go high-speed (OTG_HS)
The devices embed two USB OTG high-speed (up to 480 Mbit/s) device/host/OTG
peripheral. OTG-HS1 supports both full-speed and high-speed operations, while OTG-HS2
supports only full-speed operations. They both integrate the transceivers for full-speed
operation (12 Mbit/s) and are able to operate from the internal HSI48 oscillator. OTG-HS1
features a UTMI low-pin interface (ULPI) for high-speed operation (480 Mbit/s). When using
the USB OTG-HS1 in HS mode, an external PHY device connected to the ULPI is required.
The USB OTG HS peripherals are compliant with the USB 2.0 specification and with the
OTG 2.0 specification. They have software-configurable endpoint setting and supports
suspend/resume. The USB OTG controllers require a dedicated 48 MHz clock that is
generated by a PLL connected to the HSE oscillator.
The main features are:
Combined Rx and Tx FIFO size of 4 Kbytes with dynamic FIFO sizing
Supports the session request protocol (SRP) and host negotiation protocol (HNP)
9 bidirectional endpoints (including EP0)
16 host channels with periodic OUT support
Software configurable to OTG1.3 and OTG2.0 modes of operation
USB 2.0 LPM (Link Power Management) support
Battery Charging Specification Revision 1.2 support
Internal FS OTG PHY support
External HS or HS OTG operation supporting ULPI in SDR mode (OTG_HS1 only)
The OTG PHY is connected to the microcontroller ULPI port through 12 signals. It can
be clocked using the 60 MHz output.
Internal USB DMA
HNP/SNP/IP inside (no need for any external resistor)
For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
3.41 Ethernet MAC interface with dedicated DMA controller (ETH)
The devices provide an IEEE-802.3-2002-compliant media access controller (MAC) for
ethernet LAN communications through an industry-standard medium-independent interface
(MII) or a reduced medium-independent interface (RMII). The microcontroller requires an
external physical interface device (PHY) to connect to the physical LAN bus (twisted-pair,
fiber, etc.). The PHY is connected to the device MII port using 17 signals for MII or 9 signals
for RMII, and can be clocked using the 25 MHz (MII) from the microcontroller.
Functional overview STM32H743xI
46/231 DS12110 Rev 5
The devices include the following features:
Supports 10 and 100 Mbit/s rates
Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM
and the descriptors
Tagged MAC frame support (VLAN support)
Half-duplex (CSMA/CD) and full-duplex operation
MAC control sublayer (control frames) support
32-bit CRC generation and removal
Several address filtering modes for physical and multicast address (multicast and
group addresses)
32-bit status code for each transmitted or received frame
Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the
receive FIFO are both 2 Kbytes.
Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008
(PTP V2) with the time stamp comparator connected to the TIM2 input
Triggers interrupt when system time becomes greater than target time
3.42 High-definition multimedia interface (HDMI)
- consumer electronics control (CEC)
The devices embed a HDMI-CEC controller that provides hardware support for the
Consumer Electronics Control (CEC) protocol (Supplement 1 to the HDMI standard).
This protocol provides high-level control functions between all audiovisual products in an
environment. It is specified to operate at low speeds with minimum processing and memory
overhead. It has a clock domain independent from the CPU clock, allowing the HDMI-CEC
controller to wakeup the MCU from Stop mode on data reception.
3.43 Debug infrastructure
The devices offer a comprehensive set of debug and trace features to support software
development and system integration.
Breakpoint debugging
Code execution tracing
Software instrumentation
JTAG debug port
Serial-wire debug port
Trigger input and output
Serial-wire trace port
Trace port
Arm® CoreSight™ debug and trace components
The debug can be controlled via a JTAG/Serial-wire debug access port, using industry
standard debugging tools.
The trace port performs data capture for logging and analysis.

3. This ball should not remain floating. It can be connected to VSS or VDD. It is reserved for future use.
4. This ball should be connected to VSS.
5. Pxy_C and Pxy pins/balls are two separate pads (analog switch open). The analog switch is configured through a SYSCFG
register. Refer to the product reference manual for a detailed description of the switch configuration bits.
6. There is a direct path between Pxy_C and Pxy pins/balls, through an analog switch. Pxy alternate functions are available on
Pxy_C when the analog switch is closed. The analog switch is configured through a SYSCFG register. Refer to the product
reference manual for a detailed description of the switch configuration bits.
7. VREF+ pin, and consequently the internal voltage reference, are not available on the TFBGA100 package. On this package,
this pin is double-bonded to VDDA which can be connected to an external reference. The internal voltage reference buffer is
not available and must be kept disabled

6 Electrical characteristics
6.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
6.1.1 Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of junction temperature, supply voltage and frequencies by tests in production on
100% of the devices with an junction temperature at TJ = 25 °C and TJ = TJmax (given by the
selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes. Based on characterization, the minimum and maximum
values refer to sample tests and represent the mean value plus or minus three times the
standard deviation (mean±3).
6.1.2 Typical values
Unless otherwise specified, typical data are based on TJ = 25 °C, VDD = 3.3 V (for the
1.7 V ≤VDD ≤3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2).
6.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
6.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 12.
6.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 13.

1. N corresponds to the number of VDD pins available on the package.
2. A tolerance of +/- 20% is acceptable on decoupling capacitors.
Caution: Each power supply pair (VDD/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
below, the appropriate pins on the underside of the PCB to ensure good operation of the

6.3.6 Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code.
The current consumption is measured as described in Figure 15: Current consumption
measurement scheme.
All the run-mode current consumption measurements given in this section are performed
with a CoreMark code.
Typical and maximum current consumption
The MCU is placed under the following conditions:
All I/O pins are in analog input mode.
All peripherals are disabled except when explicitly mentioned.
The Flash memory access time is adjusted with the minimum wait states number,
depending on the fACLK frequency (refer to the table “Number of wait states according to
CPU clock (frcc_c_ck) frequency and VCORE range” available in the reference manual).
When the peripherals are enabled, the AHB clock frequency is the CPU frequency
divided by 2 and the APB clock frequency is AHB clock frequency divided by 2.
The parameters given in Table 29 to Table 37 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 23: General
operating conditions.

STM32H743xI Electrical characteristics

I/O system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate a current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Ta ble 59: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
An additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC input pins which should be
configured as analog inputs.
Caution: Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid a current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This can be done either by using pull-up/down resistors or by configuring the
pins in output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption (see Table 38: Peripheral current
consumption in Run mode), the I/Os used by an application also contribute to the current
consumption. When an I/O pin switches, it uses the current from the MCU supply voltage to
supply the I/O pin circuitry and to charge/discharge the capacitive load (internal or external)
connected to the pin:
where
ISW is the current sunk by a switching I/O to charge/discharge the capacitive load
VDDx is the MCU supply voltage
fSW is the I/O switching frequency
CL is the total capacitance seen by the I/O pin: C = CINT+ CEXT

High-speed external clock generated from a crystal/ceramic resonator
The high-speed external (HSE) clock can be supplied with a 4 to 48 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on
characterization results obtained with typical external components specified in Table 43. In
the application, the resonator and the load capacitors have to be placed as close as
possible to the oscillator pins in order to minimize output distortion and startup stabilization
time. Refer to the crystal resonator manufacturer for more details on the resonator
characteristics (frequency, package, accuracy).
For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typical), designed for high-frequency applications, and selected to
match the requirements of the crystal or resonator (see Figure 19). CL1 and CL2 are usually
the same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. The PCB and MCU pin capacitance must be included
(10 pF can be used as a rough estimate of the combined pin and board capacitance) when
sizing CL1 and CL2.
Note: For information on selecting the crystal, refer to the application note AN2867 “Oscillator
design guide for ST microcontrollers” available from the ST website www.st.com.

6.3.12 EMC characteristics
Susceptibility tests are performed on a sample basis during device characterization.
Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant
with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed.
The test results are given in Table 54. They are based on the EMS levels and classes
defined in application note AN1709.
As a consequence, it is recommended to add a serial resistor (1 kΏ) located as close as
possible to the MCU to the pins exposed to noise (connected to tracks longer than 50 mm
on PCB).
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
Corrupted program counter
Unexpected reset
Critical Data corruption (control registers...)

Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application,
executing EEMBC code, is running. This emission test is compliant with SAE IEC61967-2
standard which specifies the test board and the pin loading.
6.3.13 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse) are applied to the pins of each
sample according to each pin combination. This test conforms to the ANSI/ESDA/JEDEC
JS-001 and ANSI/ESDA/JEDEC JS-002 standards.

Static latchup
Two complementary static tests are required on six parts to assess the latchup
performance:
A supply overvoltage is applied to each power supply pin
A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with JESD78 IC latchup standard.
6.3.14 I/O current injection characteristics
As a general rule, a current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3.3 V-capable I/O pins) should be avoided during the normal
product operation. However, in order to give an indication of the robustness of the
microcontroller in cases when an abnormal injection accidentally happens, susceptibility
tests are performed on a sample basis during the device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (higher
than 5 LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out
of –5 µA/+0 µA range), or other functional failure (for example reset, oscillator frequency
deviation).
The following tables are the compilation of the SIC1/SIC2 and functional ESD results.
NegativeinducedA negative induced leakage current is caused by negative injection and
positive induced leakage current by positive injection.

The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or
source up to ±20 mA (with a relaxed VOL/VOH).
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 6.2. In particular:
The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 21).

Unless otherwise specified, the parameters given in Table 64 to Table 77 for the FMC
interface are derived from tests performed under the ambient temperature, frcc_c_ck
frequency and VDD supply voltage conditions summarized in Table 23: General operating
conditions, with the following configuration:
Output speed is set to OSPEEDRy[1:0] = 11
Measurement points are done at CMOS levels: 0.5VDD
Refer to Section 6.3.15: I/O port characteristics for more details on the input/output
characteristics.
Asynchronous waveforms and timings
Figure 23 through Figure 26 represent asynchronous waveforms and Table 64 through
Table 71 provide the corresponding timings. The results shown in these tables are obtained
with the following FMC configuration:
AddressSetupTime = 0x1
AddressHoldTime = 0x1
DataSetupTime = 0x1 (except for asynchronous NWAIT mode, DataSetupTime = 0x5)
BusTurnAroundDuration = 0x0
Capcitive load CL = 30 pF
In all timing tables, the TKERCK is the fmc_ker_ck clock period.

Power supply decoupling should be performed as shown in Figure 41 or Figure 42,
depending on whether VREF+ is connected to VDDA or not. The 100 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

6.3.32 Communications interfaces
I2C interface characteristics
The I2C interface meets the timings requirements of the I2C-bus specification and user
manual rev. 03 for:
Standard-mode (Sm): with a bit rate up to 100 kbit/s
Fast-mode (Fm): with a bit rate up to 400 kbit/s.
Fast-mode Plus (Fm+): with a bit rate up to 1Mbit/s.
The I2C timings requirements are guaranteed by design when the I2C peripheral is properly
configured (refer to RM0433 reference manual) and when the i2c_ker_ck frequency is
greater than the minimum shown in the table below:
The SDA and SCL I/O requirements are met with the following restrictions:
The SDA and SCL I/O pins are not “true” open-drain. When configured as open-drain,
the PMOS connected between the I/O pin and VDD is disabled, but is still present.
The 20 mA output drive requirement in Fast-mode Plus is not supported. This limits the
maximum load Cload supported in Fm+, which is given by these formulas:
tr(SDA/SCL)=0.8473xRpxCload
Rp(min)= (VDD-VOL(max))/IOL(max)
Where Rp is the I2C lines pull-up. Refer to
Section 6.3.15: I/O port characteristics
for the
I2C I/Os characteristics.
All I2C SDA and SCL I/Os embed an analog filter. Refer to Table 102 for the analog filter
characteristics:

7.9 Thermal characteristics
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max × JA)
Where:
TA max is the maximum ambient temperature in C,
JA is the package junction-to-ambient thermal resistance, in C/W,
PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = (VOL × IOL) + ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.
