STM32WB55VGQ6TR

RF Transceiver ICS Overview

The STM32WB55VGQ6TR is an ultra-low-power dual-core microcontroller from STMicroelectronics, featuring an Arm Cortex-M4 core running at 64 MHz and a Cortex-M0+ core operating at 32 MHz. It integrates 1 Mbyte of Flash memory and 256 Kbytes of SRAM within a UFQFPN-48 package. The device supports Bluetooth 5.3, IEEE 802.15.4, and Zigbee protocols via its integrated 2.4 GHz RF transceiver. It operates on a supply voltage range of 1.71 V to 3.6 V and includes various connectivity interfaces such as I2C, SPI, USART, and USB.

RF Transceiver ICS Feature Summary

• Dual-core architecture combining high-performance processing with low-power management capabilities
• Integrated multiprotocol wireless connectivity supporting Bluetooth LE, 802.15.4, and Zigbee standards
• Ultra-low-power design optimized for battery-operated IoT applications

RF Transceiver ICS Applications

• Smart home devices requiring multiprotocol wireless communication
• Industrial sensors utilizing Thread or Zigbee networks
• Wearable electronics needing extended battery life and Bluetooth connectivity

RF Transceiver ICS Procurement Notes

Verify the specific suffix Q6TR against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the UFQFPN-48 configuration. Cross-reference the part number with current datasheets to validate active status and regional availability constraints before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when both high computational performance and strict power efficiency are required in a single chip. The dual-core separation allows the Cortex-M0+ to handle radio stacks independently, preserving the Cortex-M4 for application logic. Consider the 1 Mbyte Flash capacity for complex firmware requirements and verify that the 48-pin package fits the mechanical constraints of the target enclosure.

RF Transceiver ICS Part Context

This model belongs to the STM32WB series, designed specifically for wireless IoT applications. It extends the standard STM32 MCU portfolio by adding robust 2.4 GHz radio capabilities while maintaining the familiar development ecosystem and peripheral set found in other STM32 families, facilitating easier migration for developers.

RF Transceiver ICS Replacement Considerations

Direct substitutes include STM32WB55VGY6TR and STM32WB55CEU6TR, which share similar core architectures but differ in package dimensions and pin counts. Verify electrical characteristics and software compatibility when transitioning between these variants.
