The STM32F091VCH6 from STMicroelectronics is a 32-bit MCU based on the ARM Cortex-M0 core. It operates at 48MHz with 256KB flash and 32KB RAM. The device supports 2V to 3.6V supply and includes DMA, I2S, POR, PWM, and WDT. Housed in a 100-UFBGA, it works from -40°C to 85°C.

  • Large memory: 256KB flash in a small BGA package for code-heavy applications.
  • Low power: 2V operation and Cortex-M0 efficiency reduce energy consumption.
  • High pin count: 100 pins provide ample GPIO for complex peripherals.
  • ST ecosystem: Compatible with STM32CubeMX and HAL libraries for rapid development.

Smart Home Hubs

48MHz Cortex-M0 with 256KB flash runs Zigbee/Thread stacks for home automation gateways.

Industrial HMI

100-pin BGA and 32KB RAM support simple graphical interfaces on TFT displays.
