General Description

The HT24LC32 is a 32K-bit 2-wire serial read/write

non-volatile memory device using the CMOS floating

gate process. Its 32768 bits of memory are organized

into 4096 words and 8 bits per word. The device is opti-

mized for use in many industrial and commercial appli-

cations where low power and low voltage operation are

essential. The HT24LC32 has high reliability endurance

of 1M erase/write cycles and 40-year data retention.
