General Description  
The HT24LC02 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 optimized for use  
in many industrial and commercial applications where  
low power and low voltage operation are essential. Up  
to eight HT24LC02 devices may be connected to the  
same 2-wire bus. The HT24LC02 is guaranteed for 1M  
erase/write cycles and 40-year data retention.
