The 128 KB SRAM is enough for moderate-size data buffers and protocol stacks; if your application runs heavy graphics or large audio buffers, you will want to budget for external PSRAM or SDRAM via the QSPI interface. ## Connectivity that covers the fieldbus landscape The STM32L475RGT7TR includes USB OTG (host and device), CANbus for industrial or automotive networks, QSPI for high-speed external Flash/RAM, and SAI for I2S audio. This is a current-production STM32L4 device, so the primary channel is franchised distribution. Independent stock also exists, typically from excess inventory buffers. If you need a reel for a pilot run or a tray for a prototype, let us know the quantity and we will check the open market and franchise back-channels.","metaTitle":"STM32L475RGT7TR 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L475RGT7TR: 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 128 KB RAM, -40 to 105°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":"Tape & Reel (TR)","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":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9455","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48af0703a3f8e43920be9e3779c075aa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L475RGT7TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32L475RGT7TR RoHS compliant?","answer":"The STM32L475RGT7TR is listed as RoHS compliant by STMicroelectronics.
