CAV93C66
4 Kb Microwire Serial CMOS
EEPROM
Description
The CAV93C66 is a 4 Kb CMOS Serial EEPROM device which is
organized as either 256 registers of 16 bits (ORG pin at V
CC
) or 512
registers of 8 bits (ORG pin at GND). Each register can be written (or
read) serially by using the DI (or DO) pin. The device features
sequential read and self−timed internal write with auto−clear. On−chip
Power−On Reset circuitry protects the internal logic against powering
up in the wrong state.

• Selectable x8 or x16 Memory Organization
• Self−timed Write Cycle with Auto−clear
• Sequential Read
• Software Write Protection
• Power−up Inadvertent Write Protection
• Low Power CMOS Technology
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• 8−lead SOIC and TSSOP Packages
• These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant

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.
