General Description
The HT24LC08 is a 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 two-wire bus. The
HT24LC08 is guaranteed for 1M erase/write cycles
and 40-year data retention.
