Description

The AT24C02B provides 2048 bits of serial electrically erasable and programmable

read-only memory (EEPROM) organized as 256 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 AT24C02B 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) versions.
