The 128 KB RAM handles moderate-size data buffers for sensor fusion or audio processing via the SAI interface. If your firmware image is pushing past 400 KB today, consider whether the next density step is needed for field-upgrade headroom. ## Connectivity and peripherals — what the bus map covers The STM32L475RET6TR brings CANbus for industrial automation, USB OTG for device-to-host or host-to-peripheral roles, QSPI for fast external Flash or RAM expansion, and SAI for I²S audio codecs. The 51 I/O lines in the 64-LQFP package give enough GPIO for a modest control panel or sensor array without forcing a larger package. The ROHS3 compliance is confirmed. ## Package and mounting — 64-LQFP with 10x10 mm body Housed in a 64-LQFP with a 10x10 mm body and 0.5 mm pitch, this is a standard surface-mount package that reflows well with typical lead-free profiles. The 64-LQFP is a common footprint across the STM32L4 series, so a board layout can often accommodate a pin-compatible upgrade within the family without a PCB spin. The mounting type is surface mount only.","metaTitle":"STM32L475RET6TR STM32L4 MCU, ARM Cortex-M4, 80MHz","metaDescription":"STM32L475RET6TR 32-bit ARM Cortex-M4 MCU, 80MHz, 512KB Flash, 128KB RAM, CAN/USB OTG/QSPI, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tape & Reel (TR) Cut Tape (CT)","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":"$9.2700","priceTiers":[{"qty":1,"price":"$9.27000","currency":"USD"},{"qty":10,"price":"$8.37100","currency":"USD"},{"qty":25,"price":"$7.98160","currency":"USD"},{"qty":100,"price":"$6.93030","currency":"USD"},{"qty":250,"price":"$6.61888","currency":"USD"},{"qty":500,"price":"$6.03484","currency":"USD"},{"qty":1000,"price":"$5.25616","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ee27105f7fa6b36caa3d17b3ebc6e43e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L475RET6TR/alternatives.json"},"ai":{"faq":[{"question":"Can STM32L475RET6TR be used as a replacement for STM32L475RET6?","answer":"Yes. The STM32L475RET6TR is the Tape & Reel packaged variant of the base part STM32L475RET6. The silicon and electrical specifications are identical. The only difference is the shipping medium: TR is Tape & Reel for automated pick-and-place, while the non-TR suffix typically ships in trays. A board designed for the STM32L475RET6 will accept the TR variant without any change."},{"question":"What is the speed and core architecture of STM32L475RET6TR?","answer":"It is a 32-bit single-core ARM Cortex-M4 with FPU running at 80 MHz. The Cortex-M4 includes DSP instructions and a single-precision floating-point unit, which offloads math-intensive tasks like sensor fusion, motor control algorithms, and audio processing from the main loop."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L475RET6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L475RET6TR when reusing this data.
