USB Type-C power delivery firmware for the Realtek RTS5453H controller, stored in a 58.4 KB RAR archive. The name carries the token BM5336, likely a board or model identifier the name does not explain, and a CRC32 checksum of 0x13BB74C3 for validating the image. Repairers use such a dump when a laptop stops charging over USB-C or the PD chip has corrupted code. Compare the checksum after extraction, read and save the original flash with a programmer, and only write it if the board identifier truly matches.
