2-Kb Microwire Serial CMOS EEPROM  
FEATURES  
DESCRIPTION  
The CAT93C56/57 is a 2-Kb CMOS Serial EEPROM  
device which is organized as either 128 registers of 16  
bits (ORG pin at VCC) 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 CAT93C56/57 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.  
„ High speed operation: 2MHz  
„ 1.8V to 5.5V supply voltage range  
„ Selectable x8 or x16 memory organization  
„ Sequential read  
„ Software write protection  
„ Power-up inadvertant write protection  
„ Low power CMOS technology  
„ 1,000,000 Program/erase cycles  
„ 100 year data retention  
„ Industrial temperature ranges  
For Ordering Information details, see page 16.  
„ RoHS-compliant 8-pin PDIP, SOIC, TSSOP and  
8-pad TDFN packages

Note: When the ORG pin is connected to VCC, the x16 organization  
is selected. When it is connected to ground, the x8 pin is selected. If  
the ORG pin is left unconnected, then am internal pullup device will  
select the x16 organization
