The 480 MHz core can saturate the internal memory bandwidth, so cache and prefetch configuration matters for sustained throughput. ## Connectivity — Ethernet confirmed, plus the full STM32H7 peripheral set Ethernet MAC is present on this variant, along with CANbus, USB OTG, dual SPI/QSPI, I²C, SAI, SPDIF, and SDIO. For a buyer cross-checking the BOM against a design that requires Ethernet, this part carries it — no external MAC needed. ## Package and temperature — 169-UFBGA, industrial range Housed in a 169-UFBGA (7x7 mm) package, this is a fine-pitch BGA that requires a multi-layer PCB with microvia capability and controlled impedance for the high-speed interfaces. Supply range of 1.62V to 3.6V allows operation from a single Li-ion cell or a regulated 3.3V rail with brownout margin.","metaTitle":"ST STM32H743AII6TR MCU, ARM Cortex-M7, 480 MHz, 2 MB Flash","metaDescription":"STM32H743AII6TR 32-bit MCU with 480 MHz Cortex-M7 core, 2 MB Flash, 1 MB RAM, Ethernet, 131 I/O, -40 to 85°C, 169-UFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"480MHz","Series":"STM32H7","Package":"Tape & Reel (TR)","RAM Size":"1M 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, Ethernet, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, QSPI, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"131","Core Processor":"ARM® Cortex®-M7","Package / Case":"169-UFBGA","Product Status":"Active","Data Converters":"A/D 36x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H743","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"169-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.5085","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5d062739b9e505bff4fe39251c67b057.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32H743AII6TR have Ethernet support?","answer":"Yes, the connectivity list includes Ethernet MAC, along with CANbus, USB OTG, SPI, I²C, and SDIO interfaces."},{"question":"What is the difference between STM32H743AII6TR and STM32H743AII6?","answer":"The TR suffix indicates Tape & Reel packaging for automated pick-and-place assembly.
