It carries 38 I/O lines, a CANbus interface, I²C, SPI, UART/USART, plus a 13-channel 12-bit ADC and a 2-channel 12-bit DAC. The 48 MHz clock is enough for sensor fusion loops, motor commutation timing, or Modbus polling at typical baud rates. The 128 KB Flash holds a modest firmware stack with room for a bootloader and field-update image — no external memory needed for most control applications.","metaTitle":"STMicroelectronics STM32F091CBU6TR ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F091CBU6TR 32-bit ARM Cortex-M0 MCU, 48 MHz speed, 128 KB Flash, 32 KB SRAM, 48-UFQFN package, -40 to 85°C.
