Product details

Overview

STM32W108B-SK from STMicroelectronics is a starter kit for the STM32W108xx wireless microcontroller family, integrating a 32-bit ARM® Cortex™-M3 core and a 2.4 GHz IEEE 802.15.4-compliant transceiver. It supports ZigBee RF4CE for remote control/target networks (e.g., TV/STB), HID devices (mouse/keyboard), and point-to-point communication using Simplified MAC.

For engineers reviewing the STM32W108B-SK datasheet, STM32W108B-SK pinout, STM32W108B-SK application, or STM32W108B-SK equivalent, this kit provides pre-flashed demonstration firmware, USB virtual COM interface, LED indicators, and IAR-compatible C development environment for rapid prototyping of 802.15.4-based embedded wireless systems.

Technical Context

The STM32W108B-SK implements a complete evaluation platform for the STM32W108B microcontroller, featuring on-board antenna, integrated USB-to-serial bridge, and dual-board configuration support (starter + optional extension). It enables real-time validation of RF performance, MAC layer behavior, and application-layer stack interoperability in both RF4CE and custom 802.15.4 deployments.

Hardware includes a 128-Kbyte Flash STM32W108B MCU, onboard LEDs for status indication, push buttons for user input, and UART/USB connectivity for host interaction and firmware reprogramming. The kit ships with preloaded demo applications covering remote control, HID emulation, and peer-to-peer data exchange.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	ARM® Cortex™-M3 32-bit RISC processor running at up to 25 MHz - enables deterministic real-time execution of wireless protocol stacks.
Wireless Standard	IEEE 802.15.4-2006 compliant 2.4 GHz transceiver - supports direct-sequence spread spectrum (DSSS) at 250 kbps for robust low-power mesh and star topologies.
Onboard Memory	128 Kbytes Flash / 16 Kbytes RAM - sufficient for ZigBee RF4CE stack plus application logic without external memory.
Interface Support	USB Virtual COM port via integrated ST-LINK/V2 bridge - allows serial debugging, firmware upload, and host PC communication without additional adapters.
Demo Capabilities	Preloaded RF4CE remote control and HID keyboard/mouse firmware - validates end-to-end interoperability with certified consumer electronics receivers.
Development Tools	Fully compatible with IAR Embedded Workbench for ARM - provides optimized C compilation, JTAG/SWD debug, and RTOS-aware profiling for production-grade firmware development.

Availability

STM32W108B-SK is available at Aetrix Electronics and suitable for wireless remote control development, HID device prototyping, IEEE 802.15.4 network validation, and RF4CE compliance testing requiring stable component supply and legacy design continuity.

Supply support for STM32W108B-SK includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The STM32W series was developed specifically for ultra-low-power, sub-GHz and 2.4 GHz IEEE 802.15.4 wireless embedded applications - targeting consumer remote controls, smart home sensors, and industrial telemetry where integrated RF + MCU reduces BOM count and PCB footprint.

FAQ

Is STM32W108B-SK still in production?

No - STM32W108B-SK is an obsolete part, superseded by STM32W108C-SK (256-Kbyte Flash version). STMicroelectronics discontinued the 128-Kbyte variant per Doc ID 17965 Rev 4, effective November 2012. Aetrix Electronics maintains limited legacy stock for design continuity and repair use only.

What software tools are required to reprogram the STM32W108B-SK?

The kit requires IAR Embedded Workbench for ARM (v6.40 or later) for full C development and debugging. ST's official STM32W firmware libraries, RF4CE stack v1.1, and Simplified MAC library are provided in the STM32W Software Package. No proprietary IDE is needed beyond standard ARM toolchains.

Does STM32W108B-SK include an external antenna connector?

No - it uses an integrated PCB trace antenna tuned for 2.4 GHz operation. There is no U.FL or SMA connector. RF performance validation must be performed with the onboard antenna; external antenna integration requires hardware modification and re-tuning of matching network components.

Can STM32W108B-SK interoperate with ZigBee HA or SE devices?

No - it implements only ZigBee RF4CE (Remote Control Profile), not ZigBee Home Automation (HA) or Smart Energy (SE) profiles. RF4CE operates as a separate cluster within ZigBee but lacks mesh routing, binding tables, and security infrastructure required for HA/SE certification.
