STM32WBA5 Multiprotocol Wireless Radio MCUs

STMicroelectronics STM32WBA5 Multiprotocol Wireless Radio MCUs are certified for BLUETOOTH® Low Energy 5.4 protocol and allow non-expert developers to add wireless communication to devices at an affordable cost easily. Based on the Arm® Cortex®-M33 core featuring TrustZone® technology, the STM32WBA series provides a high level of security, protecting data and IPs and preventing hacks or device cloning. The STM32WBA wireless MCU embeds 1Mbyte of flash memory and 128Kbytes of RAM, hosted in QFN48 and QFN32 packages. Leveraging the STM32U5 architecture, the STM32WBA components offer an ultra-low-power platform and inherited digital/analog peripherals, suitable for many applications, from industrial to smart home and consumer markets.
