Iprog Eeprom Adapter Pinout Portable -

When working with EEPROMs, understanding the pinout is critical to avoid damaging the chip or the programmer. The standard 8-pin EEPROM pinout (common in 24Cxx, 25Cxxx series) follows a specific mapping when connected to the iProg adapter. Standard 8-Pin EEPROM Pinout CS/A0 (Chip Select) Pin 2: A1 (Address 1) Pin 3: A2 (Address 2) Pin 4: VSS/GND (Ground) Pin 5: SDA/SO (Serial Data Input/Output) Pin 6: SCL/SCK (Serial Clock) Pin 7: WP/HOLD (Write Protect) Pin 8: VCC (+3.3V or +5V Power) iProg Adapter Connection Guide

Forget general-purpose programmers; the EEPROM adapter is a specialized bridge built to handle common vehicle EEPROMs. Technicians often choose it for several key reasons:

Tip: Always use a multimeter to continuity test your specific adapter version before soldering custom leads, as clone manufacturers often change PCB layouts.

| 93Cxx Pin | Name | Connect to iPROG Pin | | :--- | :--- | :--- | | 1 | CS (Chip Select) | Pin 6 (CS) | | 2 | CLK (Clock) | Pin 3 (CLK) | | 3 | DI (Data In) | Pin 4 (MOSI) | | 4 | DO (Data Out) | Pin 5 (MISO) | | 5 | GND | Pin 2 (GND) | | 6 | NC / ORG | Not Connected | | 7 | NC | Not Connected | | 8 | VCC | Pin 1 (VCC) |

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

Use a small SOIC-8 clip to jumper wires directly from the iPROG to the chip. Do not use a DIP-8 socket; use flexible silicone wires for on-board reading. When working with EEPROMs, understanding the pinout is

What is the printed on the EEPROM? (e.g., 95160, 24C02, 93C46) What automotive module are you currently working on? Are you reading the chip on-board or did you desolder it ?

An IC test clip allows you to clamp directly onto a surface-mount chip while it is still on the circuit board.

Protocol: I2C (2-wire)

Solution: Disconnect other USB peripherals and restart the software script.

Commonly found in modern engine control units (ECUs) and airbag modules.
