The STMicroelectronics STM32G070KB mainstream microcontrollers are based on high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at up to 64 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions. The devices incorporate a memory protection unit (MPU), high-speed embedded memories (128 Kbytes of Flash program memory with read protection, write protection, and 36 Kbytes of SRAM), DMA and an extensive range of system functions, enhanced I/Os and peripherals.
