It packs a 12-bit ADC (13 channels), a single 12-bit DAC, and peripherals including SPI, I²C, USART, I²S, and HDMI-CEC — enough for sensor fusion, motor control feedback, or IoT node processing in a 7x7 mm UFQFPN package. The STM32F051C4U6 is marked end-of-life (EOL). The base product number STM32F051 has a range of density options that share the same pinout and peripheral set.","metaTitle":"ST STM32F051C4U6 ARM Cortex-M0 MCU, 48MHz, 16KB Flash","metaDescription":"STMicroelectronics STM32F051C4U6 32-bit MCU, 48MHz ARM Cortex-M0, 16KB Flash, 8KB RAM, 48-UFQFPN.
