The 128 KB SRAM handles moderate data buffering — enough for a CANopen stack with several PDOs or a small GUI frame buffer over QSPI. The 82 GPIOs in the 100-LQFP package provide ample headroom for mixed-signal and display applications. ## Supply voltage and temperature — where this part fits the BOM The 1.71 V minimum supply lets this MCU run directly from two alkaline cells or a single Li-ion through most of its discharge curve, eliminating a boost regulator in low-power designs. The 3.6 V maximum covers 3.3 V rails with margin for ripple. For extended automotive or downhole use, check the STM32L4+ or automotive-grade siblings. ## Package and mounting — 100-LQFP with 82 I/O The 82 I/O count provides enough pins for a parallel LCD, external SRAM/Flash via EBI, and a sensor array without multiplexing. Surface-mount assembly with MSL 3 handling — store the reels dry and bake before reflow if the moisture barrier bag has been open past the floor-life window. This is a safe line-item for a multi-year production BOM. The base product number STM32L471 spans several density and package variants; the VGT6 suffix specifically denotes the 100-pin LQFP with 1 MB Flash. If your board layout allows a 144-pin package, the STM32L476 family shares the same core and peripheral set with additional I/O.","metaTitle":"STM32L471VGT6 STM32L4 ARM Cortex-M4 MCU, 80MHz, 1MB Flash","metaDescription":"STMicroelectronics STM32L471VGT6 32-bit ARM Cortex-M4 MCU, 80MHz, 1MB Flash, 128KB RAM, 1.71V-3.6V, -40°C to 85°C, 100-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, 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~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.6800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e53eb17b021d83c23080d8b88fab45a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can STM32L471VGT6 be replaced by STM32L476VGT6?","answer":"The STM32L476VGT6 is a close sibling in the same STM32L4 family with the same core, Flash density, and package.
