Connectivity includes CANbus, EBI/EMI for external memory expansion, I²C, IrDA, LINbus, MMC/SD card, QSPI, SAI, SPI, SWPMI, and multiple UART/USART interfaces. The data converters — a 24-channel 12-bit ADC and two 12-bit DACs — handle analog sensor inputs and control outputs without external components. An internal oscillator reduces BOM count for clock generation.","metaTitle":"STM32L471ZET6 STM32L4 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STMicroelectronics STM32L471ZET6 32-bit ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash, 128 KB SRAM, 144-LQFP, -40°C to 85°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":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L471","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.7400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e53eb17b021d83c23080d8b88fab45a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the differences between STM32L471ZET6 and STM32L476ZGT6?","answer":"Both are STM32L4 series Cortex-M4 MCUs, but STM32L476ZGT6 offers 1 MB Flash and 128 KB SRAM versus 512 KB Flash on STM32L471ZET6.
