Iprog Eeprom Adapter Pinout Portable Link

If you can read data but writes fail repeatedly, verify if Pin 3 (WP) must be manually tied to Ground or VCC via your specific adapter configuration script to un-protect the memory array.

While powerful, the iProg—particularly the more affordable clones—has several known issues that a professional user must be aware of.

: Serial Data Output (Connects to iProg RX/SDA line) Pin 3 (WP) : Write Protect Pin 4 (GND) : Ground Connection Pin 5 (SI) : Serial Data Input (Connects to iProg TX line) Pin 6 (SCK) : Serial Clock (Connects to iProg SCL line) Pin 7 (HOLD) : Hold Pin (Usually tied to VCC) Pin 8 (VCC) : 3.3V or 5V Power Supply 3. 93Cxxx Series (MicroWire Bus)

If the iProg software throws initialization faults during field use, isolate the issue systematically: iprog eeprom adapter pinout portable

It is designed to work with common 8-pin EEPROM chips and specialized, modern chips like 350806, 35080V6, 35080VP, 080D0WQ, and 160D0WQ. 2. iProg EEPROM Adapter Pinout Diagram & Connections

The standard 10-pin interface on the iProg unit side maps to the universal 8-pin EEPROM format. :

, including specialized variants like 35080V6, 35080VP, 080D0WQ, and 160D0WQ. Data Access If you can read data but writes fail

By understanding these pinout configurations and keeping your portable wiring short and properly shielded, you can reliably read, edit, and write EEPROM data directly in the field with your iProg+ programmer.

: While iProg supplies bus power over USB, in-circuit reading can back-feed power to the vehicle module, dropping the USB voltage and causing read errors. A stable, isolated power injector keeps data clean. Technical Precautions for Portable Operation 93Cxxx Series (MicroWire Bus) If the iProg software

: Power supply (3.3V or 5V depending on chip specification) 2. 25Cxxx / 95xxx Series (SPI Bus)

Disclaimer: Automotive programming involves risk. Always back up the original data before writing new data.

Note: Always verify voltage requirements in the iProg Pro Software before connecting, as some chips require 3.3V to prevent burnout. Specialized Support for 35080 and 160D chips
