The Cortex-M0 core keeps power draw low while the 48 MHz clock provides enough headroom for real-time control loops and moderate protocol stacks (e.g., Modbus RTU, CANopen via external transceiver). The 37 available I/O in a 48-LQFP package gives enough pins for a small keypad, a character LCD, and a few external peripherals without needing a port expander. ## Industrial temperature and supply — where it fits The 1.65 V minimum lets it run from a pair of alkaline cells near end-of-life, while the 3.6 V maximum covers a 3.3 V rail with margin. If you need the full industrial temperature range and the I/O count, this is the baseline STM32F0 option — no AEC-Q100 qualification here, so for automotive cabin use you would step to the STM32F0A or STM32F1 automotive-grade siblings. ## Peripheral set: analog and serial interfaces On the digital side it packs I²C, SPI, USART, and LINbus — plus HDMI-CEC for consumer-remote control and IrDA for short-range optical links. The DMA controller offloads peripheral-to-memory transfers without stalling the core, which matters when you are streaming ADC samples or driving a PWM waveform at the same time. Internal oscillator means no external crystal for many applications, saving two pins and some BOM cost. The 48-LQFP (7×7 mm) is a common, hand-solderable package with a 0.5 mm pitch. If you are dual-sourcing, the STM32F071 series shares the same base die as the STM32F051 — the main difference is the expanded analog (DAC) and connectivity (HDMI-CEC) on the 071 — but the pinout and SWD debug interface are consistent across the 48-pin LQFP variants in this family.","metaTitle":"STM32F071CBT6, STM32F0 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STMicroelectronics STM32F071CBT6 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 128 KB Flash, 16 KB RAM, 37 I/O, industrial temp -40°C to 85°C.
