FEATURES  
DESCRIPTION  
The X25C02 is a CMOS 2048-bit serial E2PROM, inter-  
nallyorganizedas256x8. TheX25C02featuresaserial  
interface and software protocol allowing operation on a  
simple three-wire bus. The bus signals are a clock input  
(SCK) plus separate data in (SI) and data out (SO) lines.  
Access to the device is controlled through a chip select  
(CS) input, allowing any number of devices to share the  
same bus.

Low Power CMOS  
—150µA Standby Current  
—2mA Active Current  
5V Power Supply  
Built-in Inadvertent Write Protection  
—Power-Up/Power-Down protection circuitry  
—Write Latch  
The X25C02 also features two additional inputs that  
provide the end user with added flexibility. By asserting  
the HOLD input, theX25C02willignoretransitionsonits  
inputs, thus allowing the host to service higher priority  
interrupts.TheWPinputcanbeusedasahardwireinput  
to the X25C02 disabling all write attempts, thus provid-  
ing a mechanism for limiting end user capability of  
altering the memory.  
—Write Protect Pin  
Self-Timed Write Cycle  
—5ms Write Cycle Time (Typical)  
High Reliability  
—Endurance: 100,000 cycles per byte  
—Data Retention: 100 Years  
—ESD protection: 2000V on all pins  
Available Packages  
The X25C02 utilizes Xicor’s proprietary Direct Write™  
cell, providing a minimum endurance of 100,000 cycles  
per byte and a minimum data retention of 100 years.
