For a motor-control loop running at 20 kHz, the core has about 2400 cycles per iteration to read the ADC, run the PI controller, and update the PWM duty cycle before the next interrupt fires. ## Package and board-fit — hand-solderable UFQFN The supplier device package is 48-UFQFPN (7x7), the same footprint. Surface-mount only — no through-hole variant exists in this series. ## Supply and temperature — runs on a single Li-ion cell Industrial temperature grade (-40°C to 105°C) qualifies the part for motor-drive enclosures, outdoor IoT gateways, and under-hood automotive auxiliary modules — the 105°C ceiling gives margin above the 85°C commercial limit. ## Peripheral set — analog and connectivity The I²S interface supports audio output, and the DMA engine moves data between peripherals and memory without CPU intervention, freeing the core for control tasks. ## Lifecycle and sourcing — active, no end-of-life risk The base product number is STM32F071 — the suffix 'CBU7' indicates 128 KB Flash, 48-pin UFQFN, and -40 to 105°C temperature range. The STM32F0 series is a long-lived family with broad toolchain support (STM32CubeIDE, HAL libraries, Arduino core).","metaTitle":"STM32F071CBU7 STM32F0 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STM32F071CBU7 MCU: ARM Cortex-M0, 48 MHz, 128 KB Flash, 16 KB RAM, 37 I/O, 48-UFQFN, -40 to 105°C.
