Runs at 24 MHz with a 2V to 3.6V supply range. Suitable for PID loops at a few kilohertz or Modbus RTU polling. ## Industrial temperature range — the deployment context ## Lifecycle reality — end-of-life planning needed End-of-life status. Last-time-buy notice issued. For legacy support, we source through independent distribution. ## Peripherals and I/O — what's on the package 37 GPIOs, I²C, SPI, USART, IrDA, and LIN interfaces cover the typical sensor-and-communication mix for a small controller. The 10-channel 12-bit ADC and dual 12-bit DAC handle analog I/O without an external converter IC.","metaTitle":"ST STM32F100CBT7BTR ARM Cortex-M3 MCU, 24 MHz, 128 KB Flash","metaDescription":"STM32F100CBT7BTR 32-bit MCU, ARM Cortex-M3 core at 24 MHz, 128 KB Flash, 8 KB RAM, industrial temp -40°C to 105°C.
