STM32WB05TZF7TR

RF Transceiver ICS Overview

The STM32WB05TZF7TR is an ultra-low-power RF System on Chip (SoC) from STMicroelectronics, designed for Bluetooth Low Energy applications. It integrates an Arm Cortex-M0+ microcontroller core operating at a maximum frequency of 64 MHz. The device features 192 Kbytes of on-chip flash memory and 24 Kbytes of RAM. It supports Bluetooth LE 5.4 certification and operates within a supply voltage range of 1.7 V to 3.6 V. The integrated 2.4 GHz radio provides an output power of 8 dBm and a sensitivity of -104 dBm, with a maximum data rate of 2 Mbps. The component is housed in a WLCSP-36 package.

RF Transceiver ICS Feature Summary

• Integrates an Arm Cortex-M0+ processor with a dedicated BlueNRG co-processor for handling timing-critical Bluetooth LE operations.
• Includes hardware security accelerators such as AES, Public Key Accelerator (PKA), and True Random Number Generator (RNG).
• Supports advanced wireless functionalities including Direction Finding (AoA/AoD), Long Range mode, and Periodic Advertising Response (PAwR).
• Features high integration by embedding balun and HSE capacitors, enabling simplified two-layer PCB designs.

RF Transceiver ICS Applications

• Bluetooth Mesh networking nodes
• IoT sensor devices requiring long battery life
• Indoor positioning systems utilizing Angle of Arrival/Departure
• Wearable electronics and health monitoring devices

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'F7' against the official STMicroelectronics datasheet to confirm it denotes the tape-and-reel packaging variant rather than a functional difference. Ensure compatibility with the WLCSP-36 footprint during procurement planning. Cross-reference the RoHS compliance status directly with the manufacturer's documentation prior to ordering.

RF Transceiver ICS Selection Notes

Select this component when a compact form factor is required due to its WLCSP-36 package size. It is suitable for designs needing Bluetooth LE 5.4 certification combined with moderate flash capacity. Consider the integrated passive components if minimizing bill of materials and board space is a priority. Evaluate the 64 MHz processing speed against application latency requirements.

RF Transceiver ICS Part Context

This part belongs to the STM32WB0 series, which focuses on cost-effective and energy-efficient wireless connectivity. The STM32WB05xZ line specifically targets applications requiring up to 192 Kbytes of flash. It shares the same core architecture and radio capabilities as other variants in the series but differs in memory size and package options.

RF Transceiver ICS Replacement Considerations

Check for STM32WB05KZV7TR if a VFQFPN-32 package is preferred over WLCSP. Verify STM32WB09TEF7TR if higher flash memory capacity is needed. Confirm pinout and software compatibility before substituting any alternative model.
