The 132-UFBGA (7x7) package packs 110 I/O lines, so this part suits sensor-fusion hubs, portable medical instruments, and industrial controllers where board area is tight but peripheral count is not. ## 320 KB SRAM — headroom for stacks and buffers 320 KB of SRAM is generous for a low-power MCU. It lets you run a real-time OS with several application threads, hold large audio or image buffers, and still have room for the stack without hitting the ceiling. If your firmware uses a graphics frame buffer or a TCP/IP stack with multiple sockets, this part keeps you out of external SRAM territory. ## Connectivity and peripherals — CAN, USB OTG, QSPI, SAI, and more The peripheral list covers CANbus for industrial networks, USB OTG for host/device operation, QSPI for fast external Flash or RAM, and SAI for audio codec interfaces. The EBI/EMI controller can drive external parallel memories or displays. With 110 I/O lines in a 7x7 mm BGA, you get a dense pinout that can handle a mixed-signal front end, a keypad matrix, and a parallel LCD all on one chip.","metaTitle":"STM32L4A6QGI6 STM32L4 ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4A6QGI6 32-bit ARM Cortex-M4 MCU at 80 MHz with 1 MB Flash, 320 KB RAM, 110 I/O, 132-UFBGA (7x7), -40 to 85°C.","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":"320K 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":"110","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":"STM32L4A6","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":"$13.1100","priceTiers":[{"qty":1,"price":"$13.11000","currency":"USD"},{"qty":10,"price":"$12.05200","currency":"USD"},{"qty":25,"price":"$11.55240","currency":"USD"},{"qty":80,"price":"$10.17875","currency":"USD"},{"qty":230,"price":"$9.67917","currency":"USD"},{"qty":440,"price":"$9.05470","currency":"USD"},{"qty":945,"price":"$8.30535","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/45a657a8843525c9cb73383b660a07f2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L4A6QGI6/alternatives.json"},"ai":{"faq":[{"question":"What is the RAM size of STM32L4A6QGI6?","answer":"The STM32L4A6QGI6 has 320 KB of SRAM (320K x 8).
