Table 1. Pin Descriptions

Symbol Type Name and Function

A0INPUT

ADDRESS INPUTS: Lowest address input in byte mode (BYTE#=VIL : ×8 bit).

Address is internally latched during an erase or a program cycle. This pin is not used in

word mode (BYTE#=VIH : ×16 bit)

A22-A1INPUT ADDRESS INPUTS: Inputs for addresses during read, erase and program operations.

Addresses are internally latched during an erase or a program cycle.

DQ15-DQ0INPUT/

OUTPUT

DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User

Interface) write cycles, outputs data during memory array, status register, query code,

identifier code reads. Data pins float to high-impedance (High Z) when the chip or

outputs are deselected. Data is internally latched during an erase or program cycle.

DQ15-DQ8 pins are not used in byte mode (BYTE#=VIL : ×8 bit).

CE0,

CE1,

CE2

INPUT

CHIP ENABLE: Activates the device’s control logic, input buffers, decoders and sense

amplifiers. When the device is de-selected, power consumption reduces to standby

levels. Refer to Table 2 to determine whether the device is selected or de-selected

depending on the state of CE0, CE1 and CE2.

RP# INPUT

RESET: When low (VIL), RP# resets internal automation and inhibits erase and program

operations, which provides data protection. RP#-high (VIH) enables normal operation.

After power-up or reset mode, the device is automatically set to read array mode.

RP# must be low during power-up/down.

OE# INPUT OUTPUT ENABLE: Gates the device’s outputs during a read cycle.

WE# INPUT

WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are

latched on the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of

WE# (whichever occurs first).

STS OPEN DRAIN

OUTPUT

STATUS: Indicates the status of the internal WSM (Write State Machine). When

configured in level mode (default mode), STS acts as a RY/BY# pin (STS is VOL when

the WSM is executing internal erase or program algorithms). When configured in one of

its pulse modes, STS can pulse to indicate erase/program completion. Refer to Table 9

for STS configuration.

BYTE# INPUT

BYTE ENABLE: BYTE# VIL places the device in byte mode (×8). In this mode, DQ15-

DQ8 is floated (High Z) and A0 is the lowest address input. BYTE# VIH places the

device in word mode (×16) and A1 is the lowest address input.

VPEN INPUT

MONITORING POWER SUPPLY VOLTAGE: VPEN is not used for power supply pin.

With VPEN≤VPENLK, block erase, (page buffer) program, block lock configuration and

OTP program cannot be executed and should not be attempted.

VCC SUPPLY

DEVICE POWER SUPPLY (2.7V-3.6V): With VCC≤VLKO, all write attempts to the

flash memory are inhibited. Device operations at invalid VCC voltage (refer to DC

Characteristics) produce spurious results and should not be attempted.

VCCQ SUPPLY INPUT/OUTPUT POWER SUPPLY (2.7V-3.6V): Power supply for all input/output

pins.

GND SUPPLY GROUND: Do not float any ground pins.

NC NO CONNECT: Lead is not internally connected; it may be driven or floated.

5. RP# at GND±0.2V ensures the lowest power consumption.

6. Command writes involving block erase, (page buffer) program, block lock configuration or OTP program are reliably

executed when VPEN=VPENH and VCC=2.7V-3.6V.

7. Refer to Table 5 for valid DIN during a write operation.

8. Never hold OE# low and WE# low at the same timing.

9. Refer to Appendix of LH28F640SP series for more information about query code.

10. STS is VOL when the WSM (Write State Machine) is executing internal block erase, (page buffer) program or OTP

program algorithms. It is High Z during when the WSM is not busy, in block erase suspend mode (with program and page

buffer program inactive), (page buffer) program suspend mode, or reset mode.

attempt, an improper command sequence was entered.

SR.3 does not provide a continuous indication of VPEN level.

The WSM interrogates and indicates the VPEN level only

after Block Erase, (Page Buffer) Program, Set Block Lock

sequences. SR.3 is not guaranteed to report accurate feedback

when VPEN≠VPENH or VPENLK.

SR.1 does not provide a continuous indication of block lock

bit. The WSM interrogates the block lock bit only after Block

Erase, (Page Buffer) Program or OTP Program command

sequences. It informs the system, depending on the attempted

operation, if the block lock bit is set. Reading the block lock

configuration codes after writing the Read Identifier Codes/

1.2.5 AC Characteristics - Write Operations (1), (2)

NOTES:

1. The timing characteristics for reading the status register during block erase, (page buffer) program, block lock

configuration and OTP program operations are the same as during read-only operations. Refer to AC Characteristics for

read-only operations.

2. A write operation can be initiated and terminated with either CE0, CE1, CE2 or WE#.

3. Sampled, not 100% tested.

4. Write pulse width low (tWP) is defined from the first edge of CE0, CE1 or CE2 that enables the device or the falling edge

of WE# (whichever occurs last) to the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of WE#

(whichever occurs first). Hence, tWP=tWLWH=tELEH=tWLEH=tELWH.

5. Write pulse width high (tWPH) is defined from the first edge of CE0, CE1 or CE2 that disables the device or the rising edge

of WE# (whichever occurs first) to the first edge of CE0, CE1 or CE2 that enables the device or the falling edge of WE#

(whichever occurs last). Hence, tWPH=tWHWL=tEHEL=tWHEL=tEHWL.

6. VPEN should be held at VPEN=VPENH until determination of block erase, (page buffer) program, block lock configuration

or OTP program success (SR.1/3/4/5=0).

7. Refer to Table 5 for valid address and data for block erase, (page buffer) program, block lock configuration and OTP

program.

8. The output delay time tAVQV or tELQV is required in addition to tWHGL (tEHGL) for read operations after command writes.

9. The timing is defined from the first edge of CE0, CE1 or CE2 that enables the device.

10. The timing is defined from the first edge of CE0, CE1 or CE2 that disables the device.

11. STS timings depend on STS configuration.

1.2.7 Block Erase, (Page Buffer) Program and Block Lock Configuration Performance(3)

NOTES:

1. Typical values measured at VCC=3.0V, VPEN=3.0V and TA=+25°C. Assumes corresponding lock bits

are not set. Subject to change based on device characterization.

2. Excludes external system-level overhead.

3. Sampled, but not 100% tested.

4. A latency time is required from writing suspend command (the first edge of CE0, CE1 or CE2 that disables

the device or the rising edge of WE#) until SR.7 going "1" or STS going High Z.

5. If the interval time from a Block Erase Resume command to a subsequent Block Erase Suspend command is shorter

than tERES and its sequence is repeated, the block erase operation may not be finished.

6. These values are valid when the page buffer is full, and the start address is aligned on a 16-word/ 32-byte boundary.

7. Program time per byte (tWHQV1/ tEHQV1) is 12.5µs/byte (typical).

Program time per word (tWHQV2/ tEHQV2) is 25.0µs/word (typical).

1. Table 5. Command Definitions

PROBLEM

While block erase or (page buffer) program is being suspended by issuing Block Erase and (Page

Buffer) Program Suspend command, memory array data can not be normally read by issuing read

array command.

WORKAROUND

Block Erase and (Page Buffer) Program Suspend command should not be issued.

STATUS

This is intended to be fixed in future devices.
