Bringing performance and security to BLE applications

22 November 2023 Telecoms, Datacoms, Wireless, IoT

Based on the Arm Cortex-M33 core running at 100 MHz with TrustZone technology, the STM32WBA series from STMicroelectronics provides a high level of security, protecting data and IPs, and preventing hacks or device cloning. Focusing on the Bluetooth Low Energy 5.3 protocol, the STM32WBA series allows non-expert developers to easily add wireless communication to a design at an affordable cost.

Leveraging the STM32U5 architecture, the STM32WBA series is an ultra-low power platform and offers inherited digital and analogue peripherals, suitable for many applications, from industrial, to smart home and consumer markets. The wireless MCU embeds a large memory to sustain both applications and connectivity activities, available with up to 1 MB of flash memory and 128 kB of RAM. A smart set of peripherals like ADC and touch sensing make this product a self-sufficient application wireless MCU.

Featuring PSA certified Level 3 and SESIP 3 IoT security standards, security is at the forefront of the STM32WBA. Data is protected for safe resource monitoring and anti-hacking, like in medical and industrial fields, including predictive maintenance applications or device fleet management. Thanks to the Arm Cortex-M33 core with Arm TrustZone technology, the STM32WBA5 isolates and protects code.

The 2.4 GHz wireless STM32WBA series provides an integrated solution to help developers streamline their design journey, while addressing market requirements.
