There are 3 BANKs, 1 BANK compose of 256 word address x 8 bit
EEPROM
There are 3 DDC interface channels, and each channel can access
each BANK independently from other ports.
2K bit X 3 BANK memory bits can be accessed from write port (Port0).
Operate voltage (3.0V to 5.5V)
Built in diode for power supply from HDMI ports and system.
Automatic erase
8 byte page write mode
Low power consumption
At write action ( 5.0V ) : 1.2mA (Typ.)
