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.
