CAT93C76/D
CAT93C76
8-Kb Microwire Serial
EEPROM
Description
The CAT93C76 is an 8−Kb Serial EEPROM memory device which
is configured as either registers of 16 bits (ORG pin at V
CC
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 ON Semiconductor’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 PDIP, SOIC and TSSOP packages.

NOTE: When the ORG pin is connected to V
CC
, the x16 organization is selected.
When it is connected to ground, the x8 organization is selected. If the ORG pin
is left unconnected, then an internal pull−up device will select the x16 organization.
