FEATURES  
DESCRIPTION  
2
2MHz Clock Rate  
The X25128 is a CMOS 131,072-bit serial E PROM,  
internally organized as 16K x 8. The X25128 features  
a Serial Peripheral Interface (SPI) 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.  
SPI Modes (0,0 & 1,1)  
16K X 8 Bits  
—32 Byte Page Mode  
Low Power CMOS  
—<1µA Standby Current  
—<5mA Active Current  
2.7V To 5.5V Power Supply  
Block Lock Protection

—Protect 1/4, 1/2 or all of E PROM Array  
Built-in Inadvertent Write Protection  
—Power-Up/Power-Down protection circuitry  
—Write Enable Latch  
The X25128 also features two additional inputs that  
provide the end user with added flexibility. By  
asserting the HOLD input, the X25128 will ignore tran-  
sitions on its inputs, thus allowing the host to service  
higher priority interrupts. The WP input can be used as  
a hardwire input to the X25128 disabling all write  
attempts to the status register, thus providing a mech-  
anism for limiting end user capability of altering 0, 1/4,  
1/2 or all of the memory.  
—Write Protect Pin  
Self-Timed Write Cycle  
—5ms Write Cycle Time (Typical)  
High Reliability  
—Endurance: 100,000 cycles  
—Data Retention: 100Years  
—ESD protection: 2000V on all pins  
14-Lead SOIC Package  
The X25128 utilizes Xicor’s proprietary Direct Write™  
cell, providing a minimum endurance of 100,000  
cycles and a minimum data retention of 100 years.
