Overview

The STM32WB1MMCH6TR is a certified Bluetooth Low Energy 5.4 module based on a dual-core architecture featuring an Arm Cortex-M4 and a Cortex-M0+ dedicated to radio and security. This 77-LGA module integrates a chip antenna, matching circuitry, and crystals to simplify RF design while maintaining a compact 6.5mm x 10mm footprint. It is designed for battery-powered IoT applications that require secure wireless connectivity and ultra-low power consumption.

Why Choose This Part

This module provides a fully integrated BOM including an IPD for reliable antenna matching and a built-in SMPS for efficiency. Security is prioritized with hardware-accelerated AES 256-bit encryption, PKA, and secure firmware installation (SFI) managed by the dedicated Cortex-M0+ core.

Applications

Industrial Sensor Nodes
Ideal for data collection using the 27 GPIOs while the dual-core architecture ensures radio stability during heavy processing tasks.
Wearable Medical Devices
Utilizes the ultra-low power modes and integrated SMPS to extend battery life in compact health-monitoring applications.
Smart Home Actuators
Leverages the 5.5dBm output power and Bluetooth 5.4 features for reliable localized control of lighting and HVAC systems.
Asset Trackers
The integrated 32MHz and 32kHz crystals and antenna reduce BOM count for space-constrained tracking hardware.
