This part is aimed at industrial control, sensor aggregation, and mixed-signal applications where a single chip handles both logic and analog front-end tasks. ## 48 MHz Cortex-M0 — enough for the control loop The core runs at 48 MHz, sufficient for real-time control loops and communication stacks. ## Analog front-end on-chip The 19-channel 12-bit ADC and dual 12-bit DAC let this MCU sample multiple analog inputs and generate analog outputs without external converters. That is useful for a panel that reads thermocouples, potentiometers, or current shunts and drives an analog meter or a setpoint voltage. No active cooling needed in most sealed cabinets.","metaTitle":"ST STM32F091VCT6U ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F091VCT6U 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 256 KB Flash, 32 KB RAM, 88 I/O, 19x12b ADC, 2x12b DAC, CAN/I²C/SPI/UART, -40°C to 85°C.
