The 480 MHz core clock is the headline number, but the RAM split (ITCM, DTCM, AXI SRAM) is what determines whether your real-time buffers fit without spillover into slower AXI space. Keep the errata sheet handy for the flash prefetch and cache behaviour at this speed. ## Peripheral set and connectivity — what the BOM gets The part carries 82 I/Os, a 36-channel 16-bit ADC, and a dual 12-bit DAC. The internal oscillator is rated as the clock source, but for Ethernet or USB you will typically route an external crystal or oscillator to the HSE pins. ## Package and temperature grade — board-level fit Housed in a 100-ball TFBGA (8x8 mm body), the STM32H742VIH6 is a surface-mount BGA. BGA rework needs a pre-bake if the moisture barrier is compromised; the 8x8 mm pitch is fine for a standard reflow profile. No underfill is required for normal shock and vibration, but a conformal coat over the assembly is advisable in condensing environments. ## Lifecycle and sourcing posture It is a current-production part from STMicroelectronics, suitable for new designs. No official second source exists, but the STM32H7 family shares a common pinout across the 100-ball TFBGA density options, so a BOM-qualified alternate within the series is a pin-compatible swap if the firmware footprint fits.","metaTitle":"STM32H742VIH6 STM32H7 MCU, ARM Cortex-M7, 480MHz, 2MB Flash","metaDescription":"STM32H742VIH6 32-bit ARM Cortex-M7 MCU at 480MHz with 2MB Flash and 692KB RAM. 36-channel 16-bit ADC, dual 12-bit DAC, extensive connectivity.","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":"Tray","RAM Size":"692K 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":"82","Core Processor":"ARM® Cortex®-M7","Package / Case":"100-TFBGA","Product Status":"Active","Data Converters":"A/D 36x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H742","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":"$12.1815","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4cee7f85c6406fc81a0ae7387ded4cdb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32H742VIH6 and STM32H743VIH6?","answer":"The STM32H743VIH6 is a pin-compatible upgrade within the same 100-TFBGA footprint, adding a second Cortex-M7 core (dual-core) and a larger RAM footprint. The STM32H742VIH6 is a single-core variant at the same 480 MHz clock.
