DESCRIPTION
The CAT93C76 is an 8K-bit Serial EEPROM memory
device which is configured as either registers of 16 bits
(ORG pin at VCC or Not Connected) or 8 bits (ORG pin
at GND). Each register can be written (or read) serially
by using the DI (or DO) pin. The CAT93C76 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, SOIC, TSSOP and 8-pad TDFN
packages.

Note: When the ORG pin is connected to VCC, x16 organization is
selected. When it is connected to ground, x8 organization is selected.
If the ORG pin is left unconnected, then an internal
pull-up device will select x16 organization.
