Description STM8A-DISCOVERY
2/4 Doc ID 023712 Rev 1
1 Description
The STM8A-DISCOVERY helps you discover the STM8AF and STM8AL automotive
microcontrollers family features and develop your applications through two dedicated
application boards that can be connected together via a LIN network.
The STM8AF board can perform both CAN and LIN communications with the MCU powered
at 5 V and is ready to be connected into a network with its integrated transceiver. The
STM8AL board manages LIN slave communication through its transceiver and uses a 4-
digit alphanumeric LCD display with the MCU powered at 3.3 V, offering low energy power
modes.
Both STM8AF and STM8AL boards include push buttons, LEDs, external connectors and
allow various configurations to take advantage of the numerous capabilities of the
microcontrollers.
2 System requirements
●Windows PC (XP, Vista, 7)
●USB cable (dual type A to mini-B) - included
3 Development toolchains
●IAR: EWSTM8
●STMicroelectronics: STVD
4 Demonstration software
The demonstration software is preloaded in the board Flash memory. It uses the trimmer
and the USER push buttons placed on the STM8AF board to switch via the LIN bus the LCD
and the LEDs of the STM8AL board. The latest versions of the demonstration source code
and associated documentation can be downloaded on the ST website.
