The connectivity block includes CANbus for industrial networking, QSPI for a serial NOR Flash or PSRAM, SAI for audio codec or digital microphone input, and SWPMI for smart-card or NFC reader links. ## Active lifecycle — no last-time-buy risk","metaTitle":"STMicroelectronics STM32L471RGT6TR MCU, ARM Cortex-M4","metaDescription":"STMicroelectronics STM32L471RGT6TR 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 1 MB Flash, 128 KB SRAM, 51 I/O, -40°C 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","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":"1MB (1M 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":"$11.0300","priceTiers":[{"qty":1,"price":"$11.03000","currency":"USD"},{"qty":10,"price":"$9.96300","currency":"USD"},{"qty":25,"price":"$9.49960","currency":"USD"},{"qty":100,"price":"$8.24830","currency":"USD"},{"qty":250,"price":"$7.87760","currency":"USD"},{"qty":500,"price":"$7.18252","currency":"USD"},{"qty":1000,"price":"$6.25574","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/083d03b90217eaa9b0b2586144a204f5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L471RGT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the core processor of the STM32L471RGT6TR?","answer":"The core is an ARM Cortex-M4, 32-bit single-core, with a floating-point unit and single-cycle multiply, clocked at 80 MHz."},{"question":"What is the closest functional equivalent or replacement for the STM32L471RGT6TR?","answer":"Within the STM32 family, the STM32L151CBU6A is a lower-performance sibling — it uses a Cortex-M3 core at 32 MHz with less Flash and fewer I/O.
