Commonly found in modern engine control units (ECUs) and airbag modules. Chip Select (Connects to DB44 Pin 6) Pin 2 (SO / DO): Serial Data Out (Connects to DB44 Pin 5) Pin 3 (WP): Write Protect (Connects to DB44 Pin 7 or VCC) Pin 4 (GND): Ground Connection Pin 5 (SI / DI): Serial Data In (Connects to DB44 Pin 4) Pin 6 (SCK): Serial Clock (Connects to DB44 Pin 3) Pin 7 (HOLD): Hold Input (Typically tied to VCC) Pin 8 (VCC): Power Supply (Connects to DB44 Pin 1) 3. Microwire Bus Series (93Cxx Families)
The iProg+ main unit utilizes a DB44 (44-pin) female connector. The standard EEPROM adapter plugs into this port and downsizes the connections to standard 8-pin layouts (DIP8/SOP8) or open wire leads. iprog eeprom adapter pinout portable
The iProg+ EEPROM adapter simplifies standard serial protocols (I2C, SPI, and MicroWire) into a unified interface. Below are the definitive portable pinout mappings for the three most common EEPROM families. 1. 24Cxxx Series (I2C Bus) Commonly found in modern engine control units (ECUs)
