STMicroelectronics STM32G070CBx Microcontrollers
STMicroelectronics STM32G070CBx Microcontrollers are based on the high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at a 64MHz frequency. These MCUs incorporate a memory protection unit (MPU), high-speed embedded memories, direct memory access (DMA), an extensive range of system functions, enhanced I/Os, and peripherals. Additional features include CRC calculation units, communication interfaces, and calendar RTC with alarm and periodic wakeup from stop/standby. STMicroelectronics STM32G070CBx Microcontrollers operate in a -40°C to +85°C temperature range and a 2V to 3.6V supply voltage range.
