The 80 available I/O pins and the rich peripheral set (CAN, USB OTG, multiple SPI/I2C, SAI audio, SDIO, and an external memory interface) make it a natural fit for industrial HMI panels, motor-control gateways, and multi-protocol field-device controllers where the BOM wants a single-chip solution. ## 100-TFBGA — board-level footprint and assembly considerations Housed in a 100-ball TFBGA (8x8 mm body), this part demands a multi-layer PCB with via-in-pad or microvia capability for fanout. The fine pitch and BGA footprint mean X-ray inspection after reflow is standard practice, and rework requires a hot-air station with a profile matched to the MSL rating on the reel label. The supply range of 1.62 V to 3.6 V covers both 1.8 V and 3.3 V I/O domains, simplifying voltage translation in mixed-rail designs. The internal oscillator, brown-out reset, and POR circuits are characterised across this range, so the MCU boots reliably from cold startup without an external supervisor in many designs.","metaTitle":"STM32H7A3VIH6Q STM32H7 MCU, 280MHz Cortex-M7, 2MB Flash","metaDescription":"STMicroelectronics STM32H7A3VIH6Q 32-bit ARM Cortex-M7 MCU, 280MHz, 2MB Flash, 1.4MB RAM, 100-TFBGA, -40 to 85°C.","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-TFBGA","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-TFBGA (8x8)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.1663","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/afca84847cefe5613ccda5eae7344216.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32H7A3VIH6Q in this component family?","answer":"Within the STM32H7A3 line, the base product number STM32H7A3 covers several Flash and RAM density variants in the same 100-TFBGA footprint.
