STM32WB55VYY6TR

RF Transceiver ICS Overview

The STM32WB55VYY6TR is an ultra-low-power dual-core microcontroller from the STM32 WB series, manufactured by STMicroelectronics. It integrates a 64 MHz Arm Cortex-M4 core with FPU and a 32 MHz Arm Cortex-M0+ core for radio management. The device features 640 Kbytes of Flash memory and 256 Kbytes of SRAM. It operates within a supply voltage range of 1.71 V to 3.6 V and supports industrial temperatures from -40°C to +85°C. The component is housed in a 100-pin WLCSP package (4.4x4.38 mm) and includes 72 general-purpose I/Os.

RF Transceiver ICS Feature Summary

• Dual-core architecture combining high-performance processing with dedicated radio management
• Integrated 2.4 GHz IEEE 802.15.4 compliant radio transceiver supporting multiple protocols
• Ultra-low-power design optimized for battery-operated IoT applications

RF Transceiver ICS Applications

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'VYY6TR' against the official STMicroelectronics datasheet DM00344191 to confirm package type and pinout compatibility. Ensure that the ordering information matches the exact part number required for your bill of materials, as variations exist within the STM32WB55xx family regarding memory size and package dimensions.

RF Transceiver ICS Selection Notes

Select this component when a balance of substantial Flash memory (640 KB) and integrated wireless capabilities is required. The WLCSP package offers a compact footprint suitable for space-constrained designs. Consider the dual-core separation if protocol stack isolation from application logic is necessary for system stability.

RF Transceiver ICS Part Context

This part belongs to the STM32 WB55xx series, which targets IoT connectivity. It differs from other variants like the STM32WB55VCY6TR primarily in memory capacity and package configuration. The series is designed to support Bluetooth 5.3, Thread, and Zigbee protocols simultaneously on a single chip.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other STM32WB55 variants such as STM32WB55VCY6TR or STM32WB55VGY6TR based on specific memory and package requirements.
