RM0529-STM32WB05xZ

STM32WB05xZ ultra-low power wireless 32-bit MCU Arm ^® -based Cortex ^® -M0+ with Bluetooth ^® LE and 2.4 GHz radio solution

Introduction

This reference manual provides complete information on how to use the STM32WB05xZ microcontroller memory and peripherals.

The STM32WB05xZ is a powerful and ultra-low power 2.4 GHz RF transceiver with a Cortex ^® -M0+ microcontroller that can operate up to 64 MHz.

The STM32WB05xZ is suitable for the implementation of applications compliant with Bluetooth ^® LE SIG specification.

The STM32WB05xZ also supports the angle of arrival (AoA) and angle of departure (AoD) Bluetooth ^® LE direction-finding features by managing:

• • The constant tone extension (CTE) inside a packet
• • The antenna switching mechanism for both AoA and AoD

Refer to the related device datasheet for detailed information.

The STM32WB05xZ microcontroller includes ST state-of-the-art patented technology.
