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
