STM32WB55VEQ6TR

RF Transceiver ICS Overview

The STM32WB55VEQ6TR is an ultra-low-power dual-core microcontroller featuring an Arm Cortex-M4 running at 64 MHz and a dedicated Cortex-M0+ operating at 32 MHz. It integrates 512 Kbytes of Flash memory and 256 Kbytes of SRAM within a 129-pin UFBGA package (7x7mm). The device includes a 2.4 GHz RF transceiver supporting Bluetooth LE 5.3, IEEE 802.15.4, Thread, Zigbee, and Matter protocols. Key electrical specifications include a supply voltage range of 1.71V to 3.6V, -100 dBm sensitivity for 802.15.4, +6 dBm output power, and operation temperatures from -40°C to 85°C.

RF Transceiver ICS Feature Summary

• Dual-core architecture with dedicated real-time radio management via Cortex-M0+
• Integrated 2.4 GHz RF transceiver with programmable output power and internal balun
• Support for multiple multiprotocol wireless standards including Bluetooth LE 5.3 and Matter
• Hardware security acceleration with AES-256 encryption capabilities

RF Transceiver ICS Applications

• Smart home devices requiring Matter protocol compliance
• Industrial IoT sensors utilizing Thread or Zigbee networks
• Bluetooth Low Energy wearables and health monitors
• Wireless gateways bridging 802.15.4 and other network types

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'Q6' indicates the industrial temperature grade (-40°C to 85°C) and the 'E' denotes the UFBGA package variant. Confirm RoHS compliance status as Ecopack2. Ensure the source document explicitly lists this part number as active. Cross-reference the pinout against the 129-pin UFBGA mechanical data sheet to prevent footprint mismatches during PCB design integration.

RF Transceiver ICS Selection Notes

Select this component when both high-performance application processing and low-power radio management are required in a single chip. The dual-core separation allows the M4 to handle complex logic while the M0+ manages radio stack tasks independently. Choose this over single-core variants if deterministic real-time radio performance is critical for maintaining connection stability in congested environments.

RF Transceiver ICS Part Context

This part belongs to the STM32WB55xx series, designed for multiprotocol wireless applications. It combines the processing power of the STM32M4 line with the connectivity features of the STM32WB family. The device targets applications needing secure, low-latency wireless communication with minimal power consumption, leveraging ST's patented radio technology for efficient spectrum usage.

RF Transceiver ICS Replacement Considerations

STM32WB55REV6TR: Different package (VFQFPN vs UFBGA) and potentially different GPIO count. STM32WB55VEY6TR: Different package (WLCSP vs UFBGA) and limited serial interfaces. Verify mechanical compatibility and interface availability before substitution.
