General Description
The HT24LC02A is a 2K-bit serial read/write
non-volatile memory device using the CMOS floating
gate process. Its 2048 bits of memory are organized into
256 words and each word is 8 bits. The device is opti-
mized for use in many industrial and commercial appli-
cations where low power and low voltage operation are
essential. Up to eight HT24LC02A devices may be con-
nected to the same 2-wire bus. The HT24LC02A is
guaranteed for 1M erase/write cycles and 40-year data
retention.
