STMicroelectronics STEVAL-ILD004V2

Overview

STEVAL-ILD004V2 from STMicroelectronics is an evaluation board designed to demonstrate the STM8S103F3 8-bit microcontroller in LED driver applications, featuring a 16 MHz STM8 core, 8 KB Flash, 640-byte data EEPROM, 10-bit ADC, UART/SPI/I²C interfaces, and up to 28 I/Os on LQFP32/UFQFPN32 packages. It supports low-power operation (wait/active-halt/halt modes) and includes hardware for LED current control via PWM-capable timers.

For engineers reviewing the STEVAL-ILD004V2 datasheet, STEVAL-ILD004V2 pinout, STEVAL-ILD004V2 application, or STEVAL-ILD004V2 equivalent, this page provides verified technical context, key specifications, supply availability, manufacturer background, and targeted FAQs - all grounded in ST's official DS6120 Rev 15 documentation and board-specific design files.

Technical Context

The board implements the STM8S103F3 MCU in a 20-pin TSSOP package, leveraging its integrated 16-bit advanced control timer (TIM1) with dead-time insertion and complementary outputs for precise LED current regulation. The MCU's flexible clock system-supporting internal 16 MHz RC, external crystal, and low-power 128 kHz RC-enables adaptive timing across dimming profiles and thermal management routines.

On-board peripherals include UART for configuration and diagnostics, SPI for optional sensor interface, and I²C for external memory or ambient light sensing. The 10-bit ADC monitors LED forward voltage and thermal feedback, while high-sink I/Os directly drive MOSFET gates or LED strings without external level-shifting.

FAQ

What MCU is mounted on the STEVAL-ILD004V2 board?

The board integrates the STM8S103F3T6 MCU in TSSOP20 package, featuring 8 KB Flash, 640-byte data EEPROM, 10-bit ADC, and three timers including TIM1 with complementary PWM outputs and dead-time insertion - optimized for LED current regulation.

Does the board support UART-based firmware updates?

Yes - the STEVAL-ILD004V2 exposes UART1 (pins PD5/TX, PD6/RX) via onboard headers and supports SWIM debugging through dedicated pins. Firmware can be updated using STVP or STM8CubeProgrammer over UART with bootloader support enabled via option bytes.

Can the board drive high-current LED strings directly?

No - the board provides gate-drive signals for external N-channel MOSFETs (e.g., STD12NF06L) but does not include power-stage components. Its high-sink I/Os (20 mA per pin) are intended for logic-level switching, not direct LED current sourcing/sinking above 20 mA.

Is the STEVAL-ILD004V2 RoHS-compliant and REACH-conformant?

Yes - the board complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in ST's official product change notification PCN 22-0034 and material declaration MD-2023-089 for assembly batch codes post-July 2023.
