With 51 general-purpose I/Os and dual 12-bit DACs plus a 16-channel 12-bit ADC, this part is built for sensor fusion, motor-control feedback, and human-machine interface tasks in industrial automation, building control, and medical equipment where moderate processing speed and deterministic response are required. At 24 MHz, the Cortex-M3 executes most single-cycle instructions, giving a raw throughput of about 24 MIPS. That is enough for a PID loop at a few kHz or Modbus RTU polling.","metaTitle":"ST STM32F100RET6BTR ARM Cortex-M3 MCU, 24 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F100RET6BTR 32-bit ARM Cortex-M3 MCU, 24 MHz, 512 KB Flash, 32K x 8 RAM, 51 I/O, -40 to 85 °C, 64-LQFP.
