General Description

The HT24LC08 is an 8K-bit serial read/write non-volatile

memory device using the CMOS floating gate process.

Its 8192 bits of memory are organized into 1024 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 two HT24LC08 devices may be connected to the

same 2-wire bus. The HT24LC08 is guaranteed for 1M

erase/write cycles and 40-year data retention.
