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.
4) For DDC2
TM
5) Wide range of power supply voltage (2.5~5.5V)
6) Page write function (Max. 8Byte)
7) Low current consumption
Operating (5V) : 1.5mA (Typ.)
Stand by (5V) : 0.1µA (Typ.)
8) Inadvertent write protection function
Built-in noise filter to SCL, SDA pin
Write protection at low power supply voltage
9) High reliable Double-Cell system
