Decoupling strategy: place a 100 nF ceramic cap within 2 mm of each VDD/VDDIO ball pair, plus a 4.7 µF to 10 µF bulk cap per supply domain. ## Connectivity and peripheral set — what the 110 I/O buy you The STM32L496QGI3 carries a full industrial connectivity suite: CANbus for fieldbus, USB OTG for dual-role device/host, QSPI for high-speed serial NOR Flash or PSRAM, and SAI for I²S audio codec interfaces. The EBI/EMI bus can gluelessly connect to external parallel SRAM, NOR Flash, or LCD controllers. With 110 I/O, you can bring out multiple UARTs, SPI, and I²C channels simultaneously without pin-mux conflicts — useful for a sensor hub or a gateway aggregating several serial protocols. The 12-bit resolution is adequate for most sensor readouts and control loops; if higher precision is needed, an external ADC would be required. Brown-out detect and reset are built in, so external supervisor ICs can be omitted in cost-sensitive designs.","metaTitle":"STM32L496QGI3 STM32L4 MCU, 80MHz, 1MB Flash, 132-UFBGA","metaDescription":"STMicroelectronics STM32L496QGI3 ARM Cortex-M4 MCU: 80MHz, 1MB Flash, 320KB SRAM, -40 to 125°C, 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":"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":"STM32L496","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"132-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.8400","priceTiers":[{"qty":1,"price":"$17.84000","currency":"USD"},{"qty":10,"price":"$16.39600","currency":"USD"},{"qty":25,"price":"$15.71600","currency":"USD"},{"qty":80,"price":"$13.84700","currency":"USD"},{"qty":416,"price":"$13.16738","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dbf144c6d56bea099c588269b06b4db3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L496QGI3/alternatives.json"},"ai":{"faq":[{"question":"How does STM32L496QGI3 compare to the STM32L151CBU6A?","answer":"The STM32L496QGI3 offers roughly 2.5x the core speed, 1 MB Flash versus the 's smaller Flash, 320 KB SRAM, 110 I/O, and extended 125°C rating.
