Key Features

  • Arm Cortex-M33 core at up to 100 MHz with TrustZone hardware security and FPU for secure IoT edge processing
  • Integrated Bluetooth LE 5.3 and IEEE 802.15.4 (Thread/Zigbee) multiprotocol radio in a single chip reduces BOM and antenna complexity
  • Ultra-low-power modes with sub-µA standby current extend battery life in coin-cell and energy-harvesting IoT designs

Applications

The STM32WBA52CGU6 targets ultra-low-power IoT edge devices such as smart home sensors, industrial wireless mesh nodes, and wearable health monitors requiring both Bluetooth LE 5.3 and IEEE 802.15.4 connectivity from a single chip. Its TrustZone-enabled Cortex-M33 core running at 100 MHz provides the compute headroom for on-device signal processing and secure over-the-air firmware updates in Thread or Zigbee mesh networks.

Frequently Asked Questions

What wireless protocols does the STM32WBA52CGU6 support, and at which frequency band does the radio operate?

The STM32WBA52CGU6 integrates a multiprotocol radio supporting Bluetooth LE 5.3 and IEEE 802.15.4 (Thread, Zigbee) operating in the 2.4 GHz ISM band, allowing a single device to serve as a BLE peripheral and a Thread or Zigbee mesh node simultaneously without external RF components.

How much flash and RAM does the STM32WBA52CGU6 provide, and how does that compare to simpler BLE-only alternatives?

The STM32WBA52CGU6 integrates 1 MB of flash and 128 KB of SRAM, which is 2x to 4x more storage than typical BLE-only SoCs in the same power class, providing sufficient space for dual-protocol stacks, secure boot firmware, and application logic without requiring external NOR flash.

Which IoT security certification requirements does the TrustZone feature of the STM32WBA52CGU6 help satisfy?

The Arm TrustZone hardware isolation on the Cortex-M33 enables secure key storage, trusted execution environments, and cryptographic acceleration, facilitating compliance with PSA Certified Level 2 and SESIP security frameworks required for connected medical devices, industrial sensors, and Matter-protocol smart home products operating on 2.4 GHz wireless networks.
