Description
The CA T93C86 is a 16 Kb Serial EEPROM memory device which
is configured as either registers of 16 bits (ORG pin at VCC) or 8 bits
(ORG pin at GND). Each register can be written (or read) serially by
using the DI (or DO) pin. The CAT93C86 is manufactured using Semiconductors 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
8ïpin DIP, 8ïpin SOIC and 8ïpad TDFN packages.
