Description

The AT24C02A/04A provides 2048/4096 bits of serial electrically erasable and pro-

grammable read-only memory (EEPROM) organized as 256/512 words of 8 bits each.

The device is optimized for use in many automotive applications where low-power and

low-voltage operation are essential. The AT24C02A/04A is available in space-saving

8-lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages and is accessed via a

two-wire serial interface. In addition, the entire family is available in 2.7V (2.7V to

5.5V) version.
