FEATURES  
DESCRIPTION  
The X25040 is a CMOS 4096-bit serial E2PROM, internally  
organized as 512 x 8. The X25040 features a Serial  
•1MHz Clock Rate  
•SPI Modes (0,0 & 1,1)  
•512 X 8 Bits  
—4 Byte Page Mode  
Peripheral Interface (SPI) and software protocol allowing  
operation on a simple three-wire bus. The bus  
•Low Power CMOS  
—150µA Standby Current  
—3mA Active Current  
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.  
•2.7V To 5.5V Power Supply  
•Block Lock Protection  
The X25040 also features two additional inputs that  
provide the end user with added flexibility. By asserting  
—Protect 1/4, 1/2 or all of E2PROM Array  
•Built-in Inadvertent Write Protection  
—Power-Up/Power-Down protection circuitry  
—Write Latch  
the HOLD input, the X25040 will ignore transitions on its  
inputs, thus allowing the host to service higher priority  
interrupts. The WP input can be used as a hardwire input to  
the X25040 disabling all write attempts, thus providing  
—Write Protect Pin  
a mechanism for limiting end user capability of altering the  
memory.  
•Self-Timed Write Cycle  
—5ms Write Cycle Time (Typical)  
•High Reliability  
—Endurance: 100,000 cycles per byte  
—Data Retention: 100 Years  
The X25040 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.  
—ESD protection: 2000V on all pins  
•8-Lead PDlP Package  
•8-Lead SOIC Package
