The STM32WB5MMG is an ultra-low-power and small form factor certified 2.4 GHz wireless module. Itsupports Bluetooth® Low Energy 5.3, Zigbee® 3.0, OpenThread, dynamic and static concurrent modes, and802.15.4 proprietary protocols. Based on STMicroelectronics STM32WB55VGY wireless microcontroller, theSTM32WB5MMG provides best-in-class RF performance thanks to its good receiver sensitivity and a highoutput power signal. Its low-power features enable extended battery life time, small coin-cell batteries or energyharvesting.
STM32WB5MMG revision Y is based on cut 2.1 of the STM32WB55VGY microcontroller. Revision X is based oncut 2.2.
The STM32WB5MMG requires no RF expertise and is the best way to speed-up any development and to reduceassociated costs. The module is completely protocol stack royalty-free.

3.1 Versions
) s  d- r9 [# w' SThe STM32WB5MMG is shipped in two finished goods versions. In this datasheet they are referred to as versions X and Y. X is the more recent version. The product version is identified by the package marking with X or Y as shown in Section 9.1.1 Device marking for SiP-LGA86.

3.2 Power supply
The power supply requirements are identical to regular STM32WB55xx and described in the datasheet. Filtering capacitors on power supply pins and components for the SMPS are already integrated into the module.
/ H/ d9 r& ~, R4 I3.2.1 SMPS
SMPS can be set to either ON or in BYPASS mode. The integrated passive components are for SMPS operation running at 4MHz. For additional information on the SMPS, check the reference manual or the application note Usage of SMPS on STM32WB Series microcontroller (AN5246).
