The integrated CANbus and USB OTG support industrial and automotive communication stacks directly, while the QSPI interface can map external Flash or RAM into the memory space for firmware updates or data logging.","metaTitle":"STM32L475RET6 ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32L475RET6 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 512 KB Flash, 128 KB SRAM, rich connectivity.","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, USB OTG","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":"STM32L475","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee27105f7fa6b36caa3d17b3ebc6e43e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L475RET6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L475RET6 and STM32L476RET6?","answer":"Both are pin-compatible STM32L4 series MCUs in the same 64-LQFP package with identical 80 MHz Cortex-M4 core and 512 KB Flash. The STM32L476RET6 typically adds a few more peripheral features (e.g., additional serial interfaces or graphics support) and may have a slightly different temperature grade. For exact differences, compare the respective datasheet feature tables — the L476 is a superset variant within the family."},{"question":"Is STM32L475RET6 pin compatible with other STM32L4 devices?","answer":"Yes, the STM32L475RET6 in the 64-LQFP package is pin-compatible with other STM32L4 MCUs in the same 64-pin footprint, such as the STM32L476RET6 and STM32L4R5ZIT6 (in 144-pin). This allows board-level upgrades within the family without a PCB spin, as long as the supply voltage and peripheral routing match."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L475RET6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L475RET6 when reusing this data.
