ROHM BU9883FV-W Technical data
Memory for Plug & Play
I2C BUS3Ports for HDMI Port
Serial EEPROM
BU9883FV-W
● Description
BU9883FV-W is for DDC 3 ports, 2K x 8 bit array 3 BANK EEPROM.
●Features
1) There are 3 BANKs, 1 BANK compose of 256 word address x 8 bit EEPROM
2) There are 3 DDC interface channels, and each channel can access each BANK independently from other ports.
3) 2K bit X 3 BANK memory bits can be accessed from write port (Port0).
4) Operate voltage (3.0V～5.5V)
5) Built in diode for power supply from HDMI ports and system.
6) Automatic erase
7) 8 byte page write mode
8) Low power consumption
Active ( 5.0V ) : 1.2mA (Typ.)
Standby ( 5.0V ) : 100μA(Max.)
9) DATA security
10) Write Protect pin can switch write port
11) Inhibit to WRITE at low VCC
12) Pin package : SSOP16pin
13) Endurance : 1,000,000 erase/write cycles
14) Data retention 40 years
15) Filtered inputs in all SCL・SDA for noise suppression
16) Shipment data all address FFh
