The 38 I/O in a 48-UFQFPN 7x7 mm package gives you enough pins for a parallel LCD data bus plus several UART and SPI peripherals while keeping board area tight. ## Peripheral set and analog integration On-chip analog includes a 13-channel 12-bit ADC and two 12-bit DAC channels, which can replace an external ADC for current-sense or temperature monitoring in a motor-drive or PSU board. Peripherals include DMA, I²S, POR, PWM, and WDT, so the part can handle a sensor-fusion loop with deterministic timing and a watchdog reset for unattended operation. The 48-UFQFPN (7x7 mm) exposed-pad package demands a QFN reflow profile and a via-stitched thermal pad under the centre paddle to pull heat into the ground plane. Without that via array, junction temperature rises quickly above 400 mA continuous I/O load. For BOM planning, this part carries no imminent last-time-buy risk, and the STM32F091 base number is shared across multiple density and package variants, which gives some supply flexibility if the 48-UFQFPN package ever tightens.","metaTitle":"STM32F091CCU7 ARM Cortex-M0 MCU, 48 MHz, 256 KB Flash","metaDescription":"STM32F091CCU7 32-bit MCU from STM32F0 series: ARM Cortex-M0 at 48 MHz, 256 KB Flash, 32K x 8 RAM, 38 I/O, -40°C to 105°C, 48-UFQFPN.
