2-Kb Microwire Serial  
CMOS EEPROM  
Description  
The CAT93C56/57 is a 2kb CMOS Serial EEPROM device which  
is organized as either 128 registers of 16 bits (ORG pin at V ) or 256

CC  
registers of 8 bits (ORG pin at GND). Each register can be written (or  
read) serially by using the DI (or DO) pin. The CAT93C56/57 features  
sequential read and selftimed internal write with autoclear. Onchip  
PowerOn Reset circuitry protects the internal logic against powering  
up in the wrong state.

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.
