The three 12-bit DACs and sixteen 16-bit ADC channels handle analog sensing and output without external converters for most mid-range precision tasks. The operating supply range spans 1.62 V to 3.6 V, which covers both 1.8 V and 3.3 V logic rails without a separate regulator for the core. Not rated for the full automotive under-hood range (125°C), but fine for cabin or chassis-adjacent applications that stay inside the 85°C boundary.","metaTitle":"STM32H7A3VIT6Q STMicroelectronics ARM Cortex-M7 MCU, 280 MHz","metaDescription":"STMicroelectronics STM32H7A3VIT6Q 32-bit ARM Cortex-M7 MCU at 280 MHz with 2 MB Flash, 1.4 MB RAM, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"280MHz","Series":"STM32H7","Package":"Tray","RAM Size":"1.4M x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"ARM® Cortex®-M7","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H7A3","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.6577","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/afca84847cefe5613ccda5eae7344216.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32H7A3VIT6Q","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32H7A3VIT6Q when reusing this data.
