Supply range from 1.71V to 3.6V covers single-cell Li-ion or a regulated 3.3V rail with headroom for brownout. ## Connectivity and analog — what the peripheral set covers The STM32L4A6ZGT6 integrates CANbus and USB OTG, which are the two interfaces that often decide whether a design needs a second MCU or a separate transceiver. The analog front end includes a 24-channel 12-bit ADC and a 2-channel 12-bit DAC — enough resolution for current-sense feedback loops or sensor voltage acquisition without an external converter. Brown-out detect and DMA are built in, so the core can service peripherals without stalling on polling. That means no last-time-buy deadline on the horizon, no forced redesign to a different pinout. The base product number is STM32L4A6, which shares the same package and peripheral map across the density options in the STM32L4A6 family. ## 144-LQFP — rework-friendly footprint The 144-LQFP (20x20 mm) is a standard quad flat pack with 0.5 mm pitch. No BGA rework station needed, no X-ray inspection for hidden joints. The exposed pad is on the bottom of the package — a via-stitched thermal land on the PCB is recommended if the design draws sustained current through multiple peripherals. The tray shipping medium is typical for this package size; reeling is available for volume assembly.","metaTitle":"STM32L4A6ZGT6 ARM Cortex-M4 MCU, 80 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4A6ZGT6: 32-bit Cortex-M4 at 80 MHz, 1 MB Flash, 320 KB SRAM, USB OTG, CAN, 12-bit ADC/DAC, 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":"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":"115","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b; 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":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.8900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/45a657a8843525c9cb73383b660a07f2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L4A6ZGT6 have USB OTG and CAN bus?","answer":"Yes.
