General Description

The HT2201 is a 1K-bit serial read/write non-volatile

memory device using the CMOS floating gate process.

Its 1024 bits of memory are organized into 128 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. The

HT2201 is guaranteed for 1 million erase/write cycles

and 40-year data retention.
