STM32WB55VCY6TR

RF Transceiver ICS Overview

The STM32WB55VCY6TR is a multiprotocol wireless microcontroller featuring an Arm Cortex-M4 core at 64 MHz and a Cortex-M0+ core at 32 MHz. It integrates a 2.4 GHz radio supporting Bluetooth 5.3, Thread, Zigbee, and IEEE 802.15.4. The device includes 256 kB Flash memory and 128 kB SRAM. It operates within a voltage range of 1.71 V to 3.6 V and supports data rates up to 2 Mbps with a maximum output power of 6 dBm. Sensitivity reaches -100 dBm. The component is housed in a 100-WLCSP package (4.4x4.38 mm) and functions across temperatures from -40°C to +85°C.

RF Transceiver ICS Feature Summary

• Dual-core architecture with dedicated real-time low-layer operation via Cortex-M0+
• Multiprotocol radio compliance with Bluetooth LE 5.3, Thread, Zigbee, and 802.15.4
• Integrated security features including AES-256 encryption engines and hardware semaphores
• Extensive peripheral set including USB, LCD driver, and capacitive sensing channels

RF Transceiver ICS Applications

• Smart home devices requiring Matter or Thread connectivity
• Bluetooth mesh sensor networks and beacons
• Industrial IoT gateways and remote control units
• Wearable health monitoring devices with low-power requirements

RF Transceiver ICS Procurement Notes

Verify the specific suffix Y6 against official STMicroelectronics documentation to confirm the 100-WLCSP package variant and pinout configuration. Ensure compatibility with design-in tools by referencing the latest datasheet DM00344191 for electrical characteristics and thermal performance limits. Cross-check manufacturing notices for any recent packaging or material changes that may impact assembly processes.

RF Transceiver ICS Selection Notes

Select this model when a compact form factor is required alongside multiprotocol wireless capabilities. The WLCSP package suits space-constrained designs compared to larger QFN or BGA options. Consider the 256 kB Flash capacity for application complexity and verify that the 128 kB SRAM meets real-time processing demands for both cores without external memory expansion.

RF Transceiver ICS Part Context

This component belongs to the STM32WB55xx series, designed for ultra-low-power wireless applications. It shares architectural similarities with other WB55 variants but differs in package type and memory configuration. The CY6 suffix specifically denotes the 100-ball WLCSP package, distinguishing it from VFQFPN or UFQFPN alternatives within the same product family.

RF Transceiver ICS Replacement Considerations

STM32WB55VGY6TR: Similar WLCSP package but higher memory capacity (1 MB Flash). STM32WB55REV6TR: Different 68-VFQFPN package with extended temperature range (-40°C to +105°C). STM32WB55CEU6TR: UFQFPN-48 package with reduced I/O count.
