Code image for a Realtek RTS5452H USB-C power delivery controller, with CRC32 0xA8E44285 and the model token M6500Q in the name. The name gives no brand or board number, so confirm that the hardware matches before use. A compressed archive of about 53 KB holds the firmware, which is written to the PD controller's SPI flash with a programmer when the USB-C port will not negotiate charging. Check the extracted image against the stated CRC, and back up the original chip so you can roll back if needed.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
