CAT93C46B  
EEPROM Serial 1-Kb  
Microwire  
Description  
The CAT93C46B is a 1Kb Microwire Serial EEPROM memory  
device which is configured as either 64 registers of 16 bits (ORG pin at  
www.onsemi.com  
V ) or 128 registers of 8 bits (ORG pin at GND). Each register can be  
CC  
written (or read) serially by using the DI (or DO) pin. The  
CAT93C46B features a selftimed internal write with autoclear.  
Onchip PowerOn Reset circuit protects the internal logic against  
powering up in the wrong state.

*CAT93C46BxxxxL (TA = 205C to +855C)  
Note: When the ORG pin is connected to V , the  
CC  
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 pullup  
device will select the x16 organization.
