STMicroelectronics — STM32WB5MMG Wireless Module

The STM32WB5MMG module from STMicroelectronics provides an easy way to implement Bluetooth® Low Energy networking using the STM32WB55 wireless microcontroller.

The module supports not only the Bluetooth Low Energy v5.3 specifications, but also the Zigbee® 3.0 and OpenThread wireless protocols, as well as proprietary IEEE 802.15.4 protocols operating at 2.4 GHz.

The STM32WB5MMG provides best-in-class RF performance thanks to its good receiver sensitivity and high output power. Its low-power features extend the run-time of small coin-cell batteries or energy harvesting systems.

The STM32WB5MMG requires no RF expertise, and helps to speed up development projects and reduce engineering costs. The module includes royalty-free protocol stacks.

The dual-core STM32WB55 MCU on which the STM32WB5MMG is based includes an embedded ultra low-power radio. It features an Arm® Cortex®-M4 core with floating point unit, DSP instructions, and a memory protection unit to enhance application security. An Arm Cortex-M0+ co-processor dedicated to managing the integrated IEEE 805.15.4 radio and the MCU cyber-protection features ensure real-time low-layer operations run smoothly without compromising application execution.

ST’s patented ultra low-power microcontroller technologies and feature integration, which include the radio balun circuitry, ensure that the STM32WB55 wireless module helps designers to meet tight power and size constraints in a wide range of IoT and wearable devices. Alongside generous provision of analog and system peripherals, the MCU’s cyber-protection and identity features include secure firmware installation, customer key storage, a hardware public key authority, and cryptographic accelerators.
