General Description

The HT24LC01/02 is a 1K/2K-bit serial

read/write non-volatile memory device using

the CMOS floating gate process. Its 1024/2048

bits of memory are organized into 128/256

words and each word is 8 bits. The device is

optimized for use in many industrial and com-

mercial applications where low power and low

voltage operation are essential. Up to eight

HT24LC01/02 devices may be connected to the

same two-wire bus. The HT24LC01/02 is guar-

anteed for 1M erase/write cycles and 40-year

data retention.
