Connectivity covers CANbus, USB OTG, QSPI, SAI (serial audio interface), and multiple I²C/SPI/UART ports, so it can talk to a CAN transceiver, an audio codec, and a QSPI NOR Flash on the same die without external bridges. ## 132-UFBGA (7x7) — layout and thermal reality That is a dense BGA — route the outer two rows with a single via-in-pad escape; inner rows need microvias or a four-layer PCB. The exposed thermal pad in the centre must be stitched to a ground plane with at least nine vias to keep the junction below 85°C at full tilt. No heatsink fits this footprint; the PCB copper is the heatsink. ## What the 80 MHz and peripherals mean for your design The 80 MHz Cortex-M4 with FPU handles a 1024-point FFT in under 1 ms at 80 MHz — enough for real-time vibration analysis or a motor-control current loop. The LCD controller and the embedded Brown-out Detect/Reset reduce external BOM count for a handheld UI.","metaTitle":"STM32L486QGI6 STM32L4 MCU, 80MHz, 1MB Flash, 132-UFBGA","metaDescription":"STMicroelectronics STM32L486QGI6 ARM Cortex-M4 MCU, 80MHz, 1MB Flash, 128KB SRAM, 1.71-3.6V, 132-UFBGA.","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":"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, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"109","Core Processor":"ARM® Cortex®-M4","Package / Case":"132-UFBGA","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L486","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"132-UFBGA (7x7)","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":"$11.08600","currency":"USD"},{"qty":25,"price":"$10.62680","currency":"USD"},{"qty":80,"price":"$9.36300","currency":"USD"},{"qty":230,"price":"$8.90348","currency":"USD"},{"qty":440,"price":"$8.32905","currency":"USD"},{"qty":945,"price":"$7.63975","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/540dbe93a69b6066cc2c513d23d9b5ee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L486QGI6/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to STM32L486QGI6?","answer":"Within the STM32L4 family, the STM32L476 series shares the same 132-UFBGA footprint and peripheral set but offers 512 KB Flash and 96 KB SRAM versus the 1 MB / 128 KB on the L486. The STM32L151CBU6A is a different generation (Cortex-M3, 32 MHz, lower I/O count) and not a pin-compatible alternative — a board redesign would be required."},{"question":"What is STM32L486QGI6's listed speed?","answer":"The core runs at 80 MHz with a single-cycle multiply-and-accumulate. That speed, combined with the FPU, makes it a fit for DSP workloads like sensor fusion or audio processing that would strain a Cortex-M3 at 32 MHz."},{"question":"Is STM32L486QGI6 compatible with STM32L4xx standard peripherals?","answer":"Yes. The STM32L486QGI6 uses the same STM32L4 peripheral library (HAL/LL) as other STM32L4xx parts. The CAN, USB OTG, QSPI, SAI, and I²C/SPI/UART blocks are register-compatible across the series, so code written for an STM32L476 or L496 ports directly with a device-header change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L486QGI6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L486QGI6 when reusing this data.
