BU9882-W/F-W/FV-W is EEPROM for storing EDID TM
based on DDC2 TM of PC monitor. Due to the independent
operating ports, and memory, this EEPROM can
simultaneously communicate with two personal computers.
There is also a switch that connects the PC to CPU in the
monitor side, so that the PC can control the monitor.
CRT monitor, LCD monitor, LCD projector
1)128word x 8bit x 2port configuration of 2kbit serial EEPROM
2) 2PC connection possible
3) 2port simultaneous read function when dual port used.
