The STMicroelectronics multiprotocol wireless and ultra-low power devices embed a powerful and ultra-low power radio compliant with the Bluetooth® SIG Low Energy specification 5.4. They operate at a frequency of up to 100 MHz. The devices integrate a 2.4 GHz RADIO supporting Bluetooth Low Energy, and make possible to use proprietary protocols. The STM32WBA50KG are based on a high-performance Arm Cortex-M33 32-bit RISC core, featuring a single-precision floating-point unit (FPU), supporting all the Arm single-precision data-processing instructions and all the data types. This core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.
