11. 2048-Bits Serial EEPROM – 24LC02
11.1. General Description
The 24LC01/02 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
commercial 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 guaranteed for 1M erase/write cycles and 40-year data retention.
