CAT93C76B/D
CAT93C76B
8-Kb Microwire Serial
EEPROM
Description
The CAT93C76B 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
CAT93C76B 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, TSSOP, MSOP
and 8−pad UDFN packages.
Features
• High Speed Operation: 4 MHz (5 V), 2 MHz (1.8 V)
• 1.8 V (1.65 V*) to 5.5 V Supply Voltage Range
• Selectable x8 or x16 Memory Organization
• Self−timed Write Cycle with Auto−clear
• Software Write Protection
• Power−up Inadvertant Write Protection
• Low Power CMOS Technology
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• Industrial and Extended Temperature Ranges
• Sequential Read
• 8−pin PDIP, SOIC, TSSOP, MSOP and 8−Pad UDFN Packages
• This Device is Pb−Free, Halogen Free/BFR Free and RoHS
Compliant

, 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.
