The thermal pad is the primary heat path — if you plan to draw continuous current through the I/O pins or run the core at full speed near the 85°C upper limit, stitch that pad to a ground plane with a grid of vias. The exposed pad also doubles as a low-inductance ground return for the ADC and DAC, which helps keep conversion noise down. ## Peripheral set for motor control and sensor fusion The STM32F071CBU6 includes DMA, PWM, and a WDT — the basic building blocks for a sensorless BLDC motor controller or a multi-axis stepper driver. The 13-channel ADC lets you sample current on all three phases plus a DC-link voltage in one conversion sequence. HDMI-CEC is also present, which is unusual at this price point and useful for consumer AV applications. That means no last-time-buy scramble and no forced redesign for the next few years.","metaTitle":"STM32F071CBU6 ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F071CBU6 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 128 KB Flash, 16 KB RAM, 13x12-bit ADC, 2x12-bit DAC, 37 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"HDMI-CEC, I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F071","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2823e521995e2779522eff0c11762a82.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F071CBU6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F071CBU6?","answer":"Within the STM32F0 series, the STM32F072CBU6 is a direct pin-compatible upgrade that adds a USB 2.0 full-speed device controller and a few extra peripherals while keeping the same 48-UFQFN footprint and supply range. If you need more Flash or RAM, stepping up to the STM32F091 family requires a package change."},{"question":"Can STM32F071CBU6 be used for motor control?","answer":"Yes, the part includes PWM timers, a 13-channel 12-bit ADC, and DMA — enough to run a sensorless BLDC or stepper motor control loop.
