That means the board needs a controlled-impedance stackup, microvias or blind vias for fanout, and a solder-mask-defined pad. From a rework standpoint: it will survive hot air if you pre-bake at 125°C for 8 hours (MSL 3 out of the bag) and use a bottom-side preheater to keep the board from warping. The thermal pad is on the underside; stitch vias to a ground plane to keep the junction temperature under 85°C ambient. For volume commitments or long-term supply agreements, the base product number STM32H743 covers the full family, so alternate density and package variants can be qualified on the same firmware.","metaTitle":"STM32H743IIK6 MCU, 480MHz Cortex-M7, 2MB Flash, 176UFBGA","metaDescription":"STMicroelectronics STM32H743IIK6 32-bit ARM Cortex-M7 MCU at 480MHz, 2MB Flash, 1MB RAM, 140 I/O, -40 to 85°C, 176+25 UFBGA.
