General Description
The HT24LC16 is a 16K-bit serial read/write non-
volatile memory device using the CMOS floating
gate process. Its 16384 bits of memory are organized
into 2048 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. Only one HT24LC16
device may be connected to the same 2-wire bus. The
HT24LC16 is guaranteed for 1M erase/write cycles
and 40-year data retention.
