Overview

The STM32WB55RGV6 is a dual-core multiprotocol wireless microcontroller that integrates an Arm Cortex-M4 for application processing and a Cortex-M0+ for managing the radio stack. It supports Bluetooth 5.3, Zigbee, and Thread concurrently, providing a high level of integration for secure, low-power wireless connectivity. This variant features 1MB of Flash memory and 256kB of SRAM in a compact 68-pin VFQFPN package.

Why Choose This Part

The dual-core architecture ensures real-time radio performance is never compromised by application-level processing. It includes specialized security features such as an AES 256-bit hardware accelerator and public key accelerator (PKA) to protect wireless communication.

Applications

Smart Home Hubs
Manages concurrent Thread and Bluetooth connections to bridge home automation devices.
Industrial IoT Sensors
Utilizes the -100dBm sensitivity and 1MB Flash for complex long-range sensor networks with over-the-air updates.
Wearable Health Monitors
Leverages ultra-low power modes like the 0.32uA Standby to extend battery life in medical and fitness devices.
