2.7V to 5.5V Power Supply  
Low Power CMOS  
The X24022 is a CMOS 2048 bit serial E PROM, inter-  
nally organized 256 x 8. The X24022 features a serial  
interface and software protocol allowing operation on a  
simple two wire bus. Three address inputs allow up to  
eight devices to share a common two wire bus.  
—Active Current Less Than 1 mA  
—Standby Current Less Than 50 µA  
Internally Organized 256 x 8  
Self Timed Write Cycle

tions requiring extended endurance. Inherent data re-  
tention is greater than 100 years. The X24022 is avail-  
able in eight pin DIP and SOIC packages.  
—Bidirectional Data Transfer Protocol  
Four Byte Page Write Operation  
—Minimizes Total Write Time Per Byte  
High Reliability  
—Endurance: 100,000 Cycles Per Byte  
—Data Retention: 100 Years
