Memory ICs

ID ROM for CRT display

BR24C21 / BR24C21F / BR24C21FJ / BR24C21FV

The BR24C21 series are 1kbits serial EEPROMs and support DDC1

and DDC2

interfaces for PLUG&PLAY

displays.

!Features

1) 128 x 8 bits serial EEPROM

2) Operating voltage range (2.5V∼5.5V)

3) Completely implements DDC1

/ DDC2

interface

for monitor identification

Transmit-Only Mode

Recovery Mode

Bi-directional Mode

4) Page write function : 8 bytes

5) Low current consumption

Active (at 5V) : 1.5mA (Typ.)

Standby (at 5V) : 10µA (Typ.)

6) DATA security

Write enable feature

Inhibit to WRITE at low Vcc

7) Compact packages

8) High reliability fine pattern CMOS technology

9) Rewriting possible up to 100,000 times

10) Data can be stored for ten years without corruption

11) Noise filters at SCL, SDA and VCLK pins
