Programming file for the Cypress CYPD6227-96BZX USB Type-C power delivery controller, listed under Apple, in a 1.15 MB RAR. This port controller handles USB-C negotiation, and a corrupted or replaced chip often leaves a MacBook without charging or port function. The firmware is written to the controller or its associated flash with a suitable programmer. Confirm the exact chip marking and board number on the logic board first, and back up any existing contents before writing.
