That means no last-time-buy clock is running, and the part is still being manufactured in volume by ST. The base product number is STM32L475, so any errata or application notes under that family apply directly. The brown-out detect and reset peripheral is built in, so an external supervisor is optional.","metaTitle":"STM32L475RCT7 STM32L4 ARM Cortex-M4 MCU, 80MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32L475RCT7 32-bit ARM Cortex-M4 MCU, 80MHz core, 256KB Flash, 128KB SRAM, -40°C 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":"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":"256KB (256K 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":"$4.7686","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48af0703a3f8e43920be9e3779c075aa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the flash memory size of STM32L475RCT7?","answer":"This is paired with 128 KB of SRAM."},{"question":"Does STM32L475RCT7 have USB OTG support?","answer":"Yes, USB OTG is listed in the connectivity block alongside CANbus, I²C, SPI, QSPI, SAI, and UART/USART interfaces."},{"question":"What is the difference between STM32L475RCT7 and STM32L476RCT6?","answer":"The STM32L476RCT6 is a close sibling in the same L4 family with the same 256 KB Flash and 64-LQFP package. The main difference is that the L476 includes a hardware cryptographic accelerator and a true random number generator, which the L475 lacks. If your application does not need on-chip AES or RNG, the L475 is a cost-effective drop-in alternative — pin-compatible and software-compatible for most peripheral code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L475RCT7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L475RCT7 when reusing this data.
