STM32WBA54CGU6TR

RF Transceiver ICS Overview

The STM32WBA54CGU6TR is an RF System on a Chip (SoC) from STMicroelectronics, featuring an Arm Cortex-M33 core operating at 100 MHz. It integrates 1 Mbyte of Flash memory and supports Bluetooth LE 6.0, IEEE 802.15.4, Thread, Matter, and Zigbee protocols. The device operates within a supply voltage range of 1.71 V to 3.6 V and functions in temperatures from -40°C to 85°C. Packaged in a UFQFPN 48 (7x7x0.55 mm) format, it includes an integrated balun and supports external power amplifiers for flexible RF design.

RF Transceiver ICS Feature Summary

• Supports multiprotocol wireless communication including Bluetooth LE 6.0, IEEE 802.15.4, Thread, Matter, and Zigbee
• Integrates ultra-low power 2.4 GHz radio with programmable output power and RX sensitivity down to -97.5 dBm
• Features Arm Cortex-M33 core with TrustZone security and integrated balun to reduce bill of materials

RF Transceiver ICS Applications

• Smart home devices requiring multiprotocol connectivity
• Industrial IoT sensors and gateways
• Bluetooth mesh networking applications
• Thread and Matter compatible smart accessories

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or verified partners. Confirm the specific ordering suffix matches the required package and temperature grade. Check current availability status as supply may be restricted. Ensure compliance with RoHS and Ecopack2 standards for environmental requirements. Validate that the UFQFPN 48 package dimensions align with your PCB layout specifications.

RF Transceiver ICS Selection Notes

Select this model when 1 Mbyte of Flash memory is required for complex firmware implementations. Choose the STM32WBA54CGU6TR over lower-capacity variants if multiprotocol support for both Bluetooth LE and IEEE 802.15.4 is necessary. Consider the integrated balun feature to simplify RF front-end design compared to solutions requiring external components. Ensure the industrial temperature range meets your operational environment constraints.

RF Transceiver ICS Part Context

This component belongs to the STM32WBA5xxx series, designed for ultra-low power wireless applications. It shares the same core architecture and RF capabilities as other members in the family but differs in memory size and package options. The series targets developers needing secure, multiprotocol connectivity in a compact form factor.

RF Transceiver ICS Replacement Considerations

The STM32WBA54KEU6TR is a related variant within the same series, offering 512 Kbytes of Flash memory instead of 1 Mbyte. Verify memory requirements before substitution, as the KEU6TR has reduced storage capacity. Both devices share similar RF performance and core specifications.
