8T49N24x EEPROM Programming Guide Application Note

EEPROM Programming Methods

Method 1: Direct Write to EEPROM Using Timing Commander and the 

Evaluation Board

This method uses Timing Commander to directly write to the attached EEPROM via the 8T49N241i or 8T49N242i Evaluation Board. 
Before beginning, make sure Timing Commander is installed, the 8T49N24x personality file is downloaded, the 8T59N24i evaluation 
board is powered, and the USB cable is plugged into the evaluation board and the computer. The following steps will perform the 
EEPROM write:
1. Inside Timing Commander, press the “Connect to the Chip” button at the top-right corner of the window.

2. If everything is connected correctly, the top box should expand and turn green.

3. Use the “WriteAll” button to reveal the Write All dialogue window.
