STMicroelectronics has introduced their first STM32-based wireless module designed to accelerate the market introduction of new Bluetooth® LE and 802.15.4 based IoT devices: the STM32WB5MMG.
The compact and ultra-low-power STM32WB5MMG is:
a complete ready-to-use subsystem in a single package; the STM32WB5MMG assures excellent radio performance out of the box and comes as a certified solution according to Bluetooth, Zigbee, and OpenThread specifications.
said the company’s Group Vice President, Microcontroller Division.
The STM32-based module aims to reduce design complexities like tuning the antenna and optimizing the RF, thus allowing quicker implementation into customer designs. It has a good receiver sensitivity and a high output power that guarantees a best-in-class RF performance, and also supports BLE 5.0, Zigbee 3.0, OpenThread, 802.15.4 proprietary protocols and even static and dynamic concurrent modes.
