The internal oscillator trims out the external crystal for cost-sensitive builds, though the HSE port is still available if you need tighter timing for CAN or USB. ## Peripheral set for industrial and mixed-signal designs Connectivity covers CANbus, I²C, SPI, UART/USART, QSPI, SAI, and SWPMI — enough for fieldbus gateways, sensor hubs, and audio codec interfaces. ## Lifecycle and supply posture For dual-sourcing resilience, the STM32L4 series includes pin-compatible density variants — the base product number STM32L471 covers a range of Flash and SRAM options in the same 100-LQFP footprint, so a BOM swap is a firmware rebuild, not a board respin.","metaTitle":"STM32L471VGT3 ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L471VGT3 32-bit ARM Cortex-M4 MCU at 80 MHz with 1 MB Flash, 128 KB SRAM, 82 I/O, 16x12b ADC, 2x12b DAC, CAN, QSPI, -40°C to 125°C.","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, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"82","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-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~125°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.5800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e53eb17b021d83c23080d8b88fab45a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L471VGT3?","answer":"The STM32L4 series includes pin-compatible density variants under the base product number STM32L471 in the same 100-LQFP footprint.
