The iPROG Pro and iPROG+ Pro offer expandability through a central DB44 connector. This 44‑pin interface allows you to connect various adapters: EEPROM, BDM, UART, RFID, K‑Line, CAN, and others. The DB44 connector is also essential for probe adapters that enable in‑circuit reading without soldering.
The standard iProg EEPROM adapter maps the main DB44 connector to standard 8-pin EEPROM layouts. Below is the typical pin configuration for standard , 25Cxxx , and 95xxx series chips on the adapter board. Standard 8-Pin EEPROM Layout (SOP8/DIP8) Pin Number Signal Name Description Pin 1 Chip Select (25/95 series) or No Connection (24 series) Pin 2 Serial Data Output Pin 3 Write Protect (Often tied to VCC or GND) Pin 4 Ground / Negative Power Supply Pin 5 SI / MOSI / SDA Serial Data Input / Serial Data Line Pin 6 Serial Clock Line Pin 7 Hold Signal (25/95 series) or No Connection Pin 8 Power Supply (Typically 3.3V or 5.0V) 3. Microchip 93C Series Pinout (Microwire)
The dedicated iProg EEPROM adapter simplifies connections to common 8-pin serial packages, such as the 24Cxxx (I2C), 93Cxxx (Microwire), and 25Cxxx/95xxx (SPI) series families.
Some in-circuit chips back-feed power into the host module, dropping the iProg's voltage. A portable rig should allow you to isolate the VCC line or inject external stable power if needed.

For chips, a separate adapter (or mode) uses pins 1(VCC), 3(SCL), 4(SDA), 8(GND).
The iProg's functionality is unlocked through its companion software. Proper installation and navigation are key to success:
The acts as a bridge. It routes the necessary lines from the DB44 connector down to simpler, localized interfaces—typically standard 8-pin dual in-line (DIP8) sockets or Zero Insertion Force (ZIF) sockets designed for 24C, 25C, and 93C series chips. 2. iProg Standard EEPROM Adapter Pinout Schema The iPROG Pro and iPROG+ Pro offer expandability
The series is a staple in automotive electronics for tasks like odometer correction, airbag resets, and immobilizer programming. Central to its versatility is the EEPROM adapter , which allows technicians to interface directly with memory chips like the 24C, 93C, and 95 series. Understanding the pinout and portable connectivity options is essential for performing reliable "in-circuit" or "on-bench" reads without damaging sensitive modules. 1. Essential EEPROM Adapter Pinouts
The iProg EEPROM adapter is a useful tool for programming and reading EEPROM chips. For users who need a portable solution, understanding the pinout is crucial for setting up the adapter with various EEPROM chips and microcontrollers. Here's a general overview:
The iProg+ main unit utilizes a standard DB44 (44-pin) high-density connector interface. All specialized adapters—including the EEPROM board, RFID adapters, and BDM/UART cables—interface directly with this connector. The standard iProg EEPROM adapter maps the main
A portable iProg EEPROM adapter setup centers on correct pin mapping, secure physical connections (clip/sockets), and attention to voltage and control pins (WP/HOLD). Following the SOIC-8 SPI pinout and the precautions above will enable reliable read/write operations on most common EEPROMs used in automotive and electronics work.
