company blog about RF Microcontroller STM32WB55VEQ6TR with FPU, BT® 5.3 and 802.15.4 Radio Solution

Shenzhen Mingjiada Electronics supplies and acquires RF microcontrollers STM32WB55VEQ6TR multi-protocol wireless 32-bit MCUs based on Arm®'s Cortex®-M4 with FPU, BT® 5.3 and 802.15.4 radio solutions.

Device Description

The STM32WB55VEQ6TR multi-protocol wireless and ultra-low-power device is embedded with a powerful ultra-low-power radio module (compliant with the BT® low-power SIG specification 5.0 and IEEE 802.15.4-2011 standards). The device contains a dedicated Arm® Cortex® -M0+ to perform all underlying real-time operations.

The device is based on the high-performance Arm® Cortex®-M4 32-bit RISC core (operating up to 64 MHz) and is designed for ultra-low power consumption. The core comes with a single-precision floating-point unit (FPU) that supports all ARM® single-precision data processing instructions and data types. It also features a DSP instruction set and a memory protection unit (MPU) for enhanced application security.

The STM32WB55VEQ6TR operates over a temperature range of -40 ~ +85 °C (+105 °C junction temperature) and a voltage range of 1.71 ~ 3.6 V. A complete set of power-saving modes is available for low-power application designs.
