8K-Bit Microwire Serial EEPROM

FEATURES

PIN CONFIGURATION

DIP Package (P, L)

SOIC Package (S, V)

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.

DESCRIPTION

The CAT93C76 is an 8K-bit Serial EEPROM memory

device which is configured as either registers of 16 bits

at GND). Each register can be written (or read) serially

by using the DI (or DO) pin. The CAT93C76 is

TSSOP Package (U,Y)

TDFN Package (RD4, ZD4)

FUNCTIONAL SYMBOL

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.
