3.17 Interface of 24LC02
3.17.1 Block Diagram
The 24LC02 is an EEPROM chip providing 2K bits storage space with 2 -wire I
After power on reset, the T71L6816A will use a sequential read command to load the
configuration settings defined by user in the 24LC02 and configure the features fr om
those settings for later normal operation. Once loading completed, the T71L6816A will
tri-state the two pins SDA and SCLK to be ready for on-line updating 24LC02 through the
parallel port.
As shown above, the user can run a simple program on WinNT/Win98 to configure the external
24LC02 through the parallel port which is popular in most personal/notebook computer.
The whole system can then be reset after the external 24LC02 been reconfigured to adapt
