It packs 115 I/O lines, a 16-channel 12-bit ADC, a dual 12-bit DAC, and a full suite of connectivity: CAN, USB OTG, SPI, I²C, UART, and an external memory interface (EBI/EMI). ## Active and available — no LTB clock ticking The 144-LQFP package is a standard, widely second-sourced footprint, so board layout risk is low. ## Industrial temperature grade — where it goes The 1.71 V minimum supply also makes it a candidate for battery-powered field instruments where the rail sags during discharge. ## Analog on-chip — fewer external parts For a sensor hub or a closed-loop motor controller, that saves board space and BOM line items. The internal oscillator further reduces external component count — just add decoupling and the supply.","metaTitle":"ST STM32L4Q5ZGT6 ARM Cortex-M4 MCU, 120MHz, 1MB Flash","metaDescription":"STM32L4Q5ZGT6 from STMicroelectronics: 32-bit ARM Cortex-M4 MCU at 120MHz, 1MB Flash, 320KB SRAM, 115 I/O, -40°C to 85°C, 144-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"120MHz","Series":"STM32L4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"115","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L4Q5","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.8878","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91f0a99a5f640d070677a4605b457dc4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L4Q5ZGT6?","answer":"Within the STM32L4 series, the STM32L4Q5ZGT6P is a pin-compatible variant (the 'P' suffix typically indicates a different package or tape-and-reel option).
