Description

The AT24C02A/04A/08A/16A provides 2048/4096/8192/16384 bits of serial electri-

cally erasable and programmable read only memory (EEPROM) organized as

256/512/1024/2048 words of 8 bits each. The device is optimized for use in many

industrial and commercial applications where low power and low voltage operation are

essential. The AT24C02A/04A/08A/16A is available in space saving 8-lead PDIP,

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

2-wire serial interface. In addition, the entire family is available in 2.7V (2.7V to 5.5V)

and 1.8V (1.8V to 5.5V) versions.
