STM32WB55RCV6

RF Transceiver ICS Overview

The STM32WB55RCV6 is an ultra-low-power dual-core microcontroller from STMicroelectronics, featuring a 64 MHz Arm Cortex-M4 and a 32 MHz Arm Cortex-M0+. It includes 256 kB of Flash memory and 128 kB of SRAM. The device operates within a voltage range of 1.71 V to 3.6 V and supports temperatures from -40°C to +85°C. It offers 49 I/Os, a 12-bit ADC with 19 channels, and interfaces including I2C, SPI, USART, and USB. Packaged in a 68-VFQFPN, it integrates Bluetooth LE 5.3/5.4, IEEE 802.15.4, Zigbee, Thread, and Matter support.

RF Transceiver ICS Feature Summary

• Hardware security accelerators including AES-256 and PKA

RF Transceiver ICS Applications

• Smart home devices requiring Matter or Thread compliance
• Bluetooth Low Energy sensor nodes
• Industrial IoT gateways
• Zigbee end devices

RF Transceiver ICS Procurement Notes

Verify the specific suffix RCV6 to confirm the 68-pin VFQFPN package and 256 kB Flash configuration. Ensure compatibility with moisture sensitivity levels and surface-mount requirements. Cross-reference official datasheets for exact pinout definitions and electrical characteristics before integration.

RF Transceiver ICS Selection Notes

Choose this model when a compact 68-pin form factor is required alongside substantial memory resources. It is suitable for applications needing simultaneous execution of complex application logic on the M4 core and strict timing protocols on the M0+ core without external wireless components.

RF Transceiver ICS Part Context

This component belongs to the STM32WB series, designed for multi-protocol wireless applications. It complements other variants like the STM32WB55CCU6 by offering a higher pin count and increased I/O availability while maintaining the same core performance and memory architecture within the ultra-low-power portfolio.

RF Transceiver ICS Replacement Considerations

The STM32WB55CCU6 serves as a direct alternative with identical core specifications but utilizes a 48-pin UFQFPN package and provides 30 I/Os instead of 49. Selection depends primarily on PCB space constraints and the number of required peripheral connections.
