STMicroelectronics STM32WBA65CGU6, 32 bit ARM Cortex M33, STM32WBA6xxx Microcontroller, 100 MHz, 1MB FLASH, 48-Pin

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 and with IEEE 802.15.4-2015. They contain a high-performance Arm Cortex M33 32-bit RISC core, and operate at a frequency of up to 100 MHz The devices integrate a 2.4 GHz RADIO supporting Bluetooth Low Energy, Matter, Thread, and ZigBee , and make possible to use proprietary protocols and concurrent operation modes. They provide support for an array of up to eight antennas, and an external power amplifier. PTA (packet traffic arbitration) interface is supported as well. The Cortex-M33 core features a single-precision floating-point unit (FPU), supporting all the Arm single-precision data-processing instructions and all the data types. This core implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.
