DESCRIPTION

The CAT93C86 is a 16K-bit Serial EEPROM memory

device which is configured as either registers of 16

Each register can be written (or read) serially by using

the DI (or DO) pin. The CAT93C86 is manufactured

using Catalyst’s advanced CMOS EEPROM floating

gate technology. The device is designed to endure

1,000,000 program/erase cycles and has a data

retention of 100 years. The device is available in 8-pin

DIP, 8-pin SOIC and 8-pad TDFN packages.
