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.
