The Cortex-M4 includes a single-cycle multiply and a hardware FPU, so it handles sensor fusion, motor-control loops, and audio processing without an external DSP. The 512 KB Flash gives room for a real-time OS, a TCP/IP stack, and application code with headroom for field-upgradeable firmware. ## Wide temperature range and rich peripheral set The peripheral list covers CANbus, I²C, SPI, UART/USART, QSPI, SAI, and SDIO — enough to connect to sensors, displays, wireless modules, and external memory without glue logic. 51 GPIOs in the 64-LQFP package leave room for parallel buses and multiple serial interfaces. ## Supply range and power management The STM32L4 family is built for low-power operation; this part includes brown-out detect, multiple sleep modes, and a DMA engine that keeps the core asleep longer during peripheral transfers.","metaTitle":"STM32L471RET3 STM32L4 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STMicroelectronics STM32L471RET3 32-bit ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash, 128 KB RAM, -40°C to 125°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L471","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9015","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8bdd65b87cb8aa084c5e1f90ea16523.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L471RET3 compatible with STM32CubeIDE?","answer":"Yes, STM32CubeIDE fully supports the STM32L4 series, including the STM32L471RET3, with peripheral configuration, code generation, and debug tools."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L471RET3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L471RET3 when reusing this data.
