General Description
The HT24LC16 is an 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 ap-
plications where low power and low voltage operation
are essential. Up to 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.
