Two 12-bit DACs and a 16-channel 12-bit ADC handle mixed-signal tasks. ## 72-WLCSP footprint — board area and rework considerations Housed in a 72-ball WLCSP measuring 4.41 x 3.76 mm, this package saves significant PCB real estate compared to a QFP or BGA of the same pin count. The wafer-level chip-scale package requires a solder-paste stencil designed for the 0.4 mm pitch and a reflow profile that follows the JEDEC MSL level specified on the reel label. For rework, a hot-air nozzle matched to the package outline and a preheat soak at 125°C reduce the risk of adjacent component disturbance. The ROHS3 compliance is current.","metaTitle":"STM32L476JGY6TR STM32L4 MCU, 80MHz, 1MB Flash, 72-WLCSP","metaDescription":"STMicroelectronics STM32L476JGY6TR 32-bit ARM Cortex-M4 MCU, 80MHz, 1MB Flash, 128KB SRAM, 57 I/O, -40 to 85°C, 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":"1MB (1M 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":"$12.0600","priceTiers":[{"qty":1,"price":"$12.06000","currency":"USD"},{"qty":10,"price":"$11.08000","currency":"USD"},{"qty":25,"price":"$10.62080","currency":"USD"},{"qty":100,"price":"$9.35770","currency":"USD"},{"qty":250,"price":"$8.89840","currency":"USD"},{"qty":500,"price":"$8.32430","currency":"USD"},{"qty":1000,"price":"$7.82850","currency":"USD"},{"qty":5000,"price":"$7.82850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e4f865ae4830d5c8c1c745b3072c2e8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L476JGY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to STM32L476JGY6TR?","answer":"The STM32L151CBU6A is a lower-cost, lower-performance sibling from the STM32L1 series: it runs a Cortex-M3 core at 32 MHz with 128 KB Flash, fewer I/O (37), and a narrower connectivity set (no CAN, no QSPI, no SAI). It is not a pin-compatible drop-in — the package and peripheral map differ — but it serves as a functional alternative for cost-sensitive designs that can trade down on speed and memory."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L476JGY6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L476JGY6TR when reusing this data.
