The 64-LQFP (10x10 mm) package with 51 I/O gives a reasonable pin count for a mixed-signal control board without needing a BGA reflow process. The exposed pad (if present on the LQFP variant) should be stitched to ground with thermal vias to keep junction temperature within limits at the 125°C end of the range. The base product number STM32L476 spans multiple density and package options, so if a board later needs a smaller Flash or a different pin count, the migration stays within the same peripheral set and register map. ## Peripherals and connectivity — what is on the bus Brown-out detect and reset, DMA, and a watchdog timer are integrated, which reduces external supervisor IC count. The internal oscillator trims to within a few percent across temperature, but for a precision timebase — say, a CAN bus with tight bit-timing — an external crystal is still the safer call.","metaTitle":"STM32L476RGT3 ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32L476RGT3 32-bit ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash, 128 KB RAM, -40°C to 125°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, LCD, 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":"STM32L476","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e4f865ae4830d5c8c1c745b3072c2e8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L476RGT3/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L476RGT3 and STM32L476RCT3?","answer":"Both share the same 64-LQFP package, 80 MHz Cortex-M4 core, and peripheral set.
