The is a critical interface used by automotive technicians to read, write, and erase non-volatile memory (EEPROM) in vehicle modules like ECUs, dashboards, and immobilizers. Its portable design and standardized pinout allow for high-speed data manipulation across various chip families, including the 24C, 25C, 93C, and 95C series . 1. Hardware Architecture & Portability
