Product details

Overview

STM8A-DISCOVERY from STMicroelectronics is a dual-board evaluation kit for automotive-grade STM8AF and STM8AL microcontrollers, featuring on-board ST-LINK/V2 debugger/programmer, 16 MHz HSE crystal, L99PM62GXP power management IC with integrated LIN/CAN transceivers and high-side drivers, and dual power supply (5 V USB and up to 14 V VBAT). It supports real-time LIN networked demonstration between boards.

For engineers reviewing the STM8A-DISCOVERY datasheet, STM8A-DISCOVERY pinout, STM8A-DISCOVERY application, or STM8A-DISCOVERY equivalent, this kit enables rapid validation of automotive MCU peripherals including LIN/CAN communication, LCD driving, ADC-based potentiometer control, low-power modes, and high-side switch sequencing in production-relevant configurations.

Technical Context

The kit comprises two physically separate but interoperable boards: the STM8AF board hosts the STM8AF5288T (64 KB Flash, CAN/LIN, 48-pin LQFP) and powers at 5 V; the STM8AL board hosts the STM8AL3L68T (32 KB Flash, LCD controller, 48-pin LQFP) and operates at 3.3 V with ultra-low-power modes. Both share common ST-LINK/V2 interface and extension headers.

LIN communication is implemented via the L99PM62GXP's embedded LIN transceiver and SPI-controlled high-side drivers, while CAN is handled directly by the STM8AF5288T's on-die controller. The 4-digit alphanumeric LCD on the STM8AL board is driven natively by the MCU's integrated LCD peripheral without external bias circuitry.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, power management ICs, sensors, and automotive-grade analog devices.

The STM8A-DISCOVERY belongs to ST's automotive evaluation platform family, engineered specifically to accelerate development of LIN- and CAN-enabled body electronics, lighting control, dashboard displays, and battery-powered automotive subsystems.

FAQ

Does STM8A-DISCOVERY support standalone CAN bus communication?

Yes - the STM8AF board implements full high-speed CAN 2.0B communication using the on-die CAN controller and the L99PM62GXP's integrated CAN transceiver. No external transceiver is needed; CAN_H/CAN_L signals are accessible via dedicated test points and extension headers for direct bus connection and signal analysis.

Can the STM8AL board operate independently from the STM8AF board?

Yes - the STM8AL board functions as a self-contained low-power LIN slave node with its own 3.3 V regulator, 4-digit LCD, two user LEDs, and push-button interface. It runs preloaded demo firmware that responds to LIN commands from the STM8AF board but can also be reprogrammed and used standalone for LCD, ADC, or sleep-mode validation.

What development tools are officially supported for STM8A-DISCOVERY?

ST officially supports IAR Embedded Workbench for STM8 (EWSTM8) and ST's free ST Visual Develop (STVD) IDE. Both integrate with the on-board ST-LINK/V2 debugger via SWIM interface. STSW-STM8069 firmware package and UM1574 user manual provide complete setup instructions and example projects for LIN/CAN co-communication.

Is the L99PM62GXP PMIC accessible for custom high-side load control?

Yes - the L99PM62GXP's four high-side drivers, wake-up inputs, and LIN/CAN control registers are fully exposed via dedicated extension headers (J1–J4). Its SPI interface allows runtime configuration of driver current limits, diagnostics, and fault reporting, enabling direct integration into custom automotive load-switching applications.
