550 MHz Cortex-M7 — what the speed rating means for your loop
The STM32H725IGK6: The ARM Cortex-M7 core runs at 550 MHz. The 1 MB Flash and 564 KB RAM support real-time OS and DMA pipelines.
Connectivity stack — Ethernet, CAN, and USB OTG on one die
This part carries an Ethernet MAC, two CAN FD controllers, and dual USB OTG — a combination that typically requires an external PHY plus a separate CAN transceiver, but the MCU itself handles the protocol layers. The MDIO interface for PHY management is also on-chip. For a panel controller or industrial gateway, this eliminates a companion network processor and simplifies the BOM. The 128 GPIOs leave enough pins for a parallel LCD and external memory bus alongside the network interfaces.
Package and layout — 176+25 UFBGA
The 176+25 UFBGA package measures 10x10 mm. It is surface-mount and requires reflow soldering.
