FFF CompatibilityStandard power/ground configurations align, but differences in power supply schemes (SMPS/internal LDO) and alternate function pin mappings require layout and software verification.Uses the identical standard LQFP-100 (14x14 mm) package style.Significantly exceeds the original part's processing speed, Flash memory, RAM capacity, and overall peripheral capabilities.
AI Summary

STM32F746VGT6 by STMicroelectronics: ARM® Cortex®-M7 STM32F7 Microcontroller IC 32-Bit 216MHz 1MB (1M x 8) FLASH 100-LQFP (14x14).

The STM32H743VIT6 is a next-generation upgrade option based on the high-performance STM32H7 series. While it resides in the same LQFP-100 package, differences in internal power supply requirements (VCORE regulation) and peripheral register mappings necessitate board design and firmware modifications.

  • Significantly higher performance with 480 MHz core clock speed vs 216 MHz
  • Double the program memory with 2MB Flash and over triple the RAM with 1MB SRAM
  • Enhanced dual-precision FPU and improved peripheral sets
  • Requires firmware migration to the STM32H7 register architecture
  • Requires circuit review of external VCAP decoupling/SMPS configurations

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
