STM32WB55CGU7

RF Transceiver ICS Overview

The STM32WB55CGU7 is an ultra-low-power dual-core microcontroller from the STM32WB series, manufactured by STMicroelectronics. It integrates a 64 MHz Arm Cortex-M4 core and a 32 MHz Arm Cortex-M0+ core within a UFQFPN-48 package. The device features 1 Mbyte of Flash memory and 256 kB of SRAM. It supports a supply voltage range of 1.71 V to 3.6 V and operates between -40°C and +105°C. Key peripherals include a 12-bit ADC with 13 channels, USB interface, SPI, I2C, LPUART, SAI, and USART.

RF Transceiver ICS Feature Summary

• Dual-core architecture combining a high-performance Cortex-M4 for application processing and a low-power Cortex-M0+ for real-time radio management.
• Integrated 2.4 GHz RF transceiver supporting Bluetooth Low Energy 5.2, IEEE 802.15.4-2011, Thread, and Zigbee protocols.
• Includes hardware cryptographic accelerators such as AES-256 for secure data protection.

RF Transceiver ICS Applications

• Smart home devices requiring multiprotocol wireless connectivity
• Industrial IoT sensors and gateways
• Wearable electronics with low power consumption requirements

RF Transceiver ICS Procurement Notes

Verify that the specific suffix 'GU7' corresponds to the UFQFPN-48 package and industrial temperature grade (-40°C to +105°C). Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

RF Transceiver ICS Selection Notes

Select this model when 1 Mbyte of program storage is required alongside extensive GPIO availability. The inclusion of LPUART and SAI interfaces distinguishes it from lower-capacity variants in the WB55 family. Consider the dual-core separation if strict real-time radio latency is critical for the application design.

RF Transceiver ICS Part Context

This component belongs to the STM32WB series, designed for multiprotocol wireless applications. It utilizes ST's patented technology to manage radio layers efficiently on the Cortex-M0+ while the Cortex-M4 handles complex application logic. The CGU7 variant specifically denotes the 1 Mbyte Flash configuration in a 48-pin package.

RF Transceiver ICS Replacement Considerations

STM32WB55CEU7 offers identical functionality but with 512 Kbytes of Flash memory. STM32WB55REV7 provides increased I/O count in a 68-pin package with 512 Kbytes of Flash. Verify pin compatibility and memory requirements when substituting.
