General Description

The HT24LC02 is a 2K-bit serial read/write non-volatile

memory device using the CMOS floating gate process.

Its 2048 bits of memory are organized into 256 words

and each word is 8 bits. The device is optimized for use

in many industrial and commercial applications where

low power and low voltage operation are essential. Up

to eight HT24LC02 devices may be connected to the

same 2-wire bus. The HT24LC02 is guaranteed for 1M

erase/write cycles and 40-year data retention.
