ST’s most affordable 32-bit MCU, makes 32-bit capabilities accessible to all developers

The STM32C0 series bridges the gap between 8- or 16-bit MCUs and higher performance 32-bit MCUs. Powered by the industry-standard Arm Cortex-M0+ core running at 48 MHz, the STM32C0 lets developers do more with less. It offers up to 128 Kbytes of Flash memory and 6 to 24 Kbytes of RAM, in a variety of 8- to 64-pin packages. 

  • Affordability: helps you reduce costs thanks to an attractive price point and an optimized BOM
  • Reliability: benefits from proven STM32 quality & reliability
  • Continuity: consistent pinout with STM32G0 and shares same technological platform
