STM32WB15CCU6

RF Transceiver ICS Overview

The STM32WB15CCU6 is a multiprotocol wireless microcontroller featuring dual-core architecture with an Arm Cortex-M4 running at 64 MHz and a dedicated Cortex-M0+ for radio management. It integrates 320 KB of Flash memory and 48 KB of SRAM within a 48-pin UFQFPN package. The device supports Bluetooth Low Energy 5.4, IEEE 802.15.4, and Zigbee protocols over a 2.4 GHz transceiver. Operating voltage ranges from 1.71 V to 3.6 V across industrial temperatures.

RF Transceiver ICS Feature Summary

• Dual-core processing separates real-time radio operations on the Cortex-M0+ from application logic on the high-performance Cortex-M4.
• Integrated hardware security features include AES-256 encryption engine, PKA, and RNG for robust data protection.
• Supports multiple wireless standards including Bluetooth Low Energy 5.4, IEEE 802.15.4, and Zigbee via a single 2.4 GHz radio.
• Includes efficient power management with an integrated SMPS converter and independent analog supply domains.

RF Transceiver ICS Applications

• Bluetooth Low Energy sensor nodes
• Zigbee end devices and routers
• IEEE 802.15.4 mesh network nodes
• Smart home actuators and controllers

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm package marking matches the 48-UFQFPN specification. Check date codes against current production status. Ensure ESD handling procedures are followed during assembly. Validate pinout compatibility with target PCB footprint before ordering.

RF Transceiver ICS Selection Notes

Choose this model when multi-protocol support is required alongside high computational performance. The dedicated Cortex-M0+ ensures deterministic radio timing without interfering with main application tasks. Select if specific memory capacity of 320 KB Flash is necessary. Consider thermal requirements as the device operates up to 105°C junction temperature.

RF Transceiver ICS Part Context

This part belongs to the STM32WB15 series, designed for ultra-low-power wireless applications. It complements other STM32WB variants by offering higher memory density. The U6 suffix indicates the specific 48-pin packaging configuration suitable for compact embedded designs requiring extensive I/O connectivity.

RF Transceiver ICS Replacement Considerations

STM32WB15CCU6TR serves as the tape-and-reel alternative for automated manufacturing. Verify that the TR variant maintains identical electrical characteristics and pinout compatibility. No functional substitutes exist outside the STM32WB family due to unique radio integration.
