BU9882F-E2 数据手册

BU9882/F/FV-W

●Description

The BU9882 ICs are dual port EEPROMs compatible with the DDC2^TM. 2 independent ports allow 2 EDID channels to be

read simultaneously.

●Features

1) Designed for use with DDC2^TM

2) 2-port simultaneous read function

3) Operating voltage range: 2.5V-5.5V

4) Page write function: 8bytes

5) Low power consumption:

Active (at 5V) : 1.5mA(typ)

Stand-by (at 5V) : 0.1μA(typ)

6) Data security

Write protection with WP

Write protection at low power supply voltage

7) Various package types available: DIP14 / SOP14 / SSOP14

8) Initial data: FFh

9) Data retention: 10years

10) Rewriting possible up to 100,000 times
