Product details

Overview

STM8S-DISCOVERY from STMicroelectronics is an evaluation and development board built around the STM8S105C6T6 8-bit microcontroller (32 KB Flash, 2 KB RAM, 1 KB EEPROM), powered via USB, and featuring embedded ST-Link debugger, touch-sensing button, user LED, and 3.3 V/5 V selectable power supply for rapid prototyping of STM8S Access line applications.

For engineers reviewing the STM8S-DISCOVERY datasheet, STM8S-DISCOVERY pinout, STM8S-DISCOVERY application, or STM8S-DISCOVERY equivalent, this board supports SWIM-based debugging, IAR Embedded Workbench® and ST Visual Develop toolchains, and ships with preloaded touch-driven LED blink demo firmware for immediate hands-on evaluation.

Technical Context

The board implements a complete STM8S105C6T6 evaluation environment with on-board ST-Link v2 debugger providing SWIM interface access, eliminating need for external debug hardware. It exposes all MCU I/O pins via a standard 0.1" extension header compatible with breadboards and peripheral modules.

Power is derived solely from USB (5 V), regulated to either 3.3 V or 5 V for target MCU operation; the touch sensing button uses STM8S's integrated capacitive touch sensing library, and the user LED connects directly to PD4 for visual feedback during firmware execution.

Key Specifications

ParameterValue and Actual Design Meaning
Core MCUSTM8S105C6T6: 16 MHz max clock, 32 KB Flash for application code + bootloader space
On-board DebuggerEmbedded ST-Link v2: Provides SWIM programming and real-time debugging without external tools
Power SupplySelectably regulated 3.3 V or 5 V output: Enables testing of both voltage domains supported by STM8S Access MCUs
Touch InterfaceDedicated capacitive touch button: Uses built-in STM8S touch sensing library for zero-external-component proximity input
I/O ExpansionFull-pin 0.1" male header: Exposes all MCU GPIOs, reset, SWIM, and power rails for custom peripheral integration
Firmware DemoPreloaded touch-responsive LED blinker: Demonstrates real-time touch event handling and timer-based LED control in Flash

Availability

STM8S-DISCOVERY is available at Aetrix Electronics and suitable for embedded education, MCU evaluation, and low-cost STM8S firmware prototyping requiring stable component supply, quick-turn lab deployment, and consistent toolchain validation.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, analog ICs, power devices, and sensors for industrial, automotive, and consumer markets.

The STM8S-DISCOVERY belongs to ST's Discovery evaluation platform family, engineered to lower entry barriers for STM8S 8-bit MCU adoption through plug-and-play debugging, standardized headers, and application-ready firmware examples.

FAQ

Does STM8S-DISCOVERY require an external debugger?

No. It integrates ST-Link v2 hardware, enabling full SWIM-based programming and debugging over a single USB cable-no additional JTAG/SWD probe or adapter is needed for development or firmware updates.

Which IDEs and compilers are officially supported?

ST officially supports IAR Embedded Workbench® for STM8 and ST Visual Develop (STVD) with Cosmic C compiler. Both toolchains provide full register-level debugging, flash programming, and peripheral configuration for the STM8S105C6T6 on this board.

Can the board operate at both 3.3 V and 5 V simultaneously?

No. The voltage selector switch configures the board's regulated output to either 3.3 V or 5 V-not both. The selected voltage powers the STM8S105C6T6 core and I/O, ensuring compliance with its absolute maximum ratings and logic level requirements.

Is the touch sensing button compatible with custom firmware?

Yes. The touch button connects to PC5 and is fully accessible in user code. ST provides touch sensing library source files and application notes, allowing integration into custom projects without hardware modification or external components.
