Connectivity includes CANbus, I²C, SPI, UART/USART, USB OTG, QSPI, and SAI — enough for sensor hubs, motor-control interfaces, or human-machine-interface panels. The 57 I/O lines and the integrated LCD driver expand the application space to segmented displays and keypads. ## 72-WLCSP — footprint and layout considerations The 72-WLCSP package (4.41 x 3.76 mm) requires a via-in-pad or microvia process to route the 57 I/O and supply balls.","metaTitle":"STM32L476JEY6TR ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32L476JEY6TR 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 512 KB Flash, 128 KB SRAM, 57 I/O, 72-WLCSP.","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, 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":"57","Core Processor":"ARM® Cortex®-M4","Package / Case":"72-UFBGA, WLCSP","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":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"72-WLCSP (4.41x3.76)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.3700","priceTiers":[{"qty":1,"price":"$9.37000","currency":"USD"},{"qty":10,"price":"$8.46900","currency":"USD"},{"qty":25,"price":"$8.07480","currency":"USD"},{"qty":100,"price":"$7.01120","currency":"USD"},{"qty":250,"price":"$6.69612","currency":"USD"},{"qty":500,"price":"$6.10528","currency":"USD"},{"qty":1000,"price":"$5.31750","currency":"USD"},{"qty":5000,"price":"$4.92361","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e4f865ae4830d5c8c1c745b3072c2e8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L476JEY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the core processor of STM32L476JEY6TR?","answer":"It uses an ARM Cortex-M4 core, 32-bit single-core, running at 80 MHz."},{"question":"Does STM32L476JEY6TR have an equivalent or replacement?","answer":"The STM32L151CBU6A is a functional alternative from the STM32L1 series, but it uses a Cortex-M3 at 32 MHz with fewer I/O and less Flash.
