General Description
The HT24LC04 is a 4K-bit serial read/write non-
volatile memory device using the CMOS floating
gate process. Its 4096 bits of memory are organized
into 512 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 four HT24LC04 devices
may be connected to the same two-wire bus. The
HT24LC04 is guaranteed for 1M erase/write cycles
and 40-year data retention.
