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.
