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.
