The 37 I/O lines are accessible on the perimeter, which keeps routing manageable on a two-layer board. The base product number is STM32F071, and the STM32F0 family has broad distribution support, so second-sourcing through a pin-compatible STM32F0 variant with matching Flash and RAM is feasible if supply tightens.","metaTitle":"STM32F071CBU6TR ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F071CBU6TR 32-bit MCU, 48 MHz Cortex-M0, 128 KB Flash, 16 KB RAM, 48-UFQFN, -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":"Tape & Reel (TR)","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":"$2.6028","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2823e521995e2779522eff0c11762a82.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F071CBU6TR/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F071CBU6TR be used for motor control?","answer":"Yes, the 48 MHz Cortex-M0 core, PWM timers, and 13-channel 12-bit ADC are sufficient for sensorless or low-end field-oriented control of small motors. The 16 KB SRAM limits the lookup-table size, so vector control with full observer may need a larger-RAM sibling."},{"question":"What is the closest pin-compatible alternative to STM32F071CBU6TR?","answer":"Within the STM32F0 family, the STM32F070 and STM32F072 series share the same 48-pin UFQFN footprint and peripheral set, with differences in Flash and RAM density. The STM32F072 adds a USB 2.0 full-speed interface. For a direct drop-in with identical memory, the STM32F071CBT6 (LQFP-48) is pin-compatible but uses a different package body."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F071CBU6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F071CBU6TR when reusing this data.
