It also integrates a 16-channel 12-bit ADC and two 12-bit DACs, plus an LCD segment driver — a combination that suits mixed-signal control panels, smart sensors, and portable instruments. The 140 I/O lines in the 169-UFBGA package give plenty of headroom for parallel displays, keypads, and sensor arrays. ## Package and temperature grade — layout and environment Housed in a 169-ball UFBGA measuring 7x7 mm, the STM32L4Q5AGI6 is a compact BGA that requires careful PCB layout — fine-pitch routing, via-in-pad if the board density demands it, and attention to the ball-out for signal breakout. Surface-mount assembly with standard reflow profiles applies; MSL level should be verified from the latest STM32L4 product documentation. The base product number STM32L4Q5 covers a family of density and package variants; if a pin-compatible alternative is needed for dual-sourcing, the STM32L4 series includes several siblings with the same 169-UFBGA footprint and peripheral set, differing mainly in Flash/SRAM size.","metaTitle":"STM32L4Q5AGI6 ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4Q5AGI6 32-bit ARM Cortex-M4 MCU at 120 MHz with 1 MB Flash, 320 KB SRAM, USB OTG, LCD support.","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":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"169-UFBGA","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":"169-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.1500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91f0a99a5f640d070677a4605b457dc4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L4Q5AGI6 support USB OTG and LCD?","answer":"Yes, the STM32L4Q5AGI6 includes USB OTG connectivity and a segment LCD controller, along with CANbus, multiple serial interfaces, and an EBI/EMI bus."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4Q5AGI6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4Q5AGI6 when reusing this data.
