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.
