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 in-
dustrial and commercial applications where
low power and low voltage operation are essen-
tial. Up to four HT24LC04 devices may be con-
nected to the same two-wire bus. The
HT24LC04 is guaranteed for 1M erase/write cy-
cles and 40-year data retention.
