Description  
The AT24C02A/04A/08A provides 2048/4096/8192 bits of serial electrically erasable  
and programmable read only memory (EEPROM) organized as 256/512/1024 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 is available in space saving 8-pin PDIP, 8-lead JEDEC SOIC,  
and 8-lead TSSOP (AT24C02A/04A) packages and is accessed via a 2-wire serial  
interface. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V  
to 5.5V), 2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
