AT24C02A
Description
The AT24C02A/04A provides 2048/4096 bits of serial electrically erasable and program-
mable read-only memory (EEPROM) organized as 256/512 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 is available in
space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP and 8-lead TSSOP pack-
ages and is accessed via a two-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.
