STM32WB35CEU7A

RF Transceiver ICS Overview

The STM32WB35CEU7A is a multiprotocol wireless microcontroller integrating an Arm Cortex-M4 core at 64 MHz and a dedicated Cortex-M0+ core at 32 MHz. It features 512 Kbytes of Flash memory, 96 Kbytes of SRAM, and supports Bluetooth v5.3, IEEE 802.15.4, Zigbee, Thread, and Matter protocols. The device operates within a voltage range of 1.71V to 3.6V, with receive current between 4.5mA and 7.9mA, and transmit current from 5.2mA to 12.7mA. It includes AES-256 encryption, PKA, RNG, and a 2.4GHz radio with -100dBm sensitivity. Packaged in a 48-UFQFPN (7x7mm) exposed pad, it functions across -40°C to +105°C.

RF Transceiver ICS Feature Summary

• Dual-core architecture combining high-performance Cortex-M4 for application processing and ultra-low-power Cortex-M0+ for real-time protocol handling
• Multiprotocol wireless connectivity supporting Bluetooth LE 5.3, IEEE 802.15.4, Zigbee, Thread, and Matter standards
• Integrated security features including dual AES engines, Public Key Accelerator (PKA), and True Random Number Generator (RNG)
• Enhanced inter-processor communication via IPCC channels and hardware semaphores for efficient resource sharing

RF Transceiver ICS Applications

• Smart home devices requiring multiprotocol interoperability
• Industrial sensor nodes utilizing Thread or Zigbee networks
• Bluetooth mesh lighting and control systems
• Wearable electronics with low-power requirements
• IoT gateways bridging different wireless standards

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'EU7A' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges (-40°C to +105°C). Cross-reference RoHS compliance status and MSL rating before integration into production workflows.

RF Transceiver ICS Selection Notes

Select this component when both Bluetooth LE 5.3 and IEEE 802.15.4 support are required in a single chip. The 512KB Flash size suits applications needing moderate code storage without external memory. Consider the dual-core design for separating real-time radio tasks from main application logic to optimize power consumption.

RF Transceiver ICS Part Context

Part of the STM32WB35xx series, designed for ultra-low-power wireless IoT applications. It shares architectural similarities with the STM32WB55xx but offers reduced memory capacity. The device belongs to the mainstream STM32 family based on Arm Cortex-M processors, targeting connectivity and digital signal processing needs.

RF Transceiver ICS Replacement Considerations

STM32WB55CEU7A offers identical functionality with increased memory (1MB Flash, 256KB SRAM). STM32WB35CC provides alternative packaging options. Verify pinout and software compatibility when substituting within the WB35xx family.
