CAV93C56
2 Kb Microwire Serial CMOS
EEPROM
Description
The CAV93C56 is a 2 Kb CMOS Serial EEPROM device which is
organized as either 128 registers of 16 bits (ORG pin at V ) or 256

registers of 8 bits (ORG pin at GND). Each register can be written (or
read) serially by using the DI (or DO) pin. The CAV93C56 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.

ORDERING INFORMATION
See detailed ordering and shipping information in the package
dimensions section on page 10 of this data sheet.
NOTE: When the ORG pin is connected to V , the x16 organization is selected.
When it is connected to ground, the x8 pin is selected. If the ORG pin is left
unconnected, then an internal pullup device will select the x16 organization.
