STM32WB55CCU6

RF Transceiver ICS Overview

The STM32WB55CCU6 is a dual-core ultra-low-power microcontroller from the STM32WB series, featuring an Arm Cortex-M4 core running at up to 64 MHz and an Arm Cortex-M0+ core operating at 32 MHz. It integrates 256 KB of Flash memory and 128 KB of SRAM within a 48-pin UFQFPN package. The device supports Bluetooth 5.3, Thread, and Zigbee protocols over the 2.405–2.48 GHz frequency range with GFSK modulation. Key electrical parameters include a supply voltage range of 1.71 V to 3.6 V, a maximum clock frequency of 64 MHz, and a 12-bit ADC resolution.

RF Transceiver ICS Feature Summary

• Dual-core architecture combining high-performance processing with dedicated real-time protocol handling
• Integrated sub-GHz and 2.4 GHz radio transceiver supporting multiple wireless standards
• Hardware security engines including AES-256, PKA, and RNG for data protection

RF Transceiver ICS Applications

• Smart home devices requiring Thread or Zigbee connectivity
• Bluetooth Low Energy wearables and sensors
• Industrial IoT gateways and controllers

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'U6' corresponds to the 48-pin UFQFPN package variant when sourcing. Confirm that the required firmware supports the intended wireless protocol stack, as the hardware enables multiple standards. Ensure ESD precautions are observed during handling due to the sensitive RF components integrated into the silicon die.

RF Transceiver ICS Selection Notes

Choose this component when both high computational performance and multi-protocol wireless capabilities are required in a single chip. The dual-core design allows separation of application logic from network stack management. Consider the 256 KB Flash limit for complex applications; larger variants exist if code size exceeds this capacity.

RF Transceiver ICS Part Context

This part belongs to the STM32WB55xx family, designed for multiprotocol wireless applications. It shares architectural similarities with the STM32WB35xx but offers higher memory capacity. The CCU6 designation specifically identifies the pinout and package configuration distinct from other series members like the STM32WL.

RF Transceiver ICS Replacement Considerations

Direct substitutes include other STM32WB55xx variants with different packages or memory sizes, such as STM32WB55CCV6. Cross-family replacements like the STM32WL55 require verification of radio compatibility and pinout differences.
