FEATURES  
DESCRIPTION  
5MHz Clock Rate  
Low Power CMOS  
The X25138 is a CMOS 128K-bit serial E2PROM,  
internally organized as 16K x 8. The X25138 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.

Block Lock™ Protection  
Protect 1/4, 1/2 or all of E2PROM Array  
Programmable Hardware Write Protection  
In-Circuit Programmable ROM Mode  
Built-in Inadvertent Write Protection  
Power-Up/Down protection circuitry  
Write Enable Latch  
The X25138 also features two additional inputs that  
provide the end user with added flexibility. By  
asserting the HOLD input, the X25138 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 X25138 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: 100 Years  
ESD protection: 2000V on all pins  
Packages  
The X25138 utilizes Xicor’s proprietary Direct WriteTM  
cell, providing a minimum endurance of 100,000  
cycles and a minimum data retention of 100 years.
