2. Description

The AT24HC02B 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 industrial and commercial applications where low-power

and low-voltage operation are essential. The AT24HC02B 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 1.8V (1.8V to

5.5V) version.
