DESCRIPTION
The X25138 is a CMOS 128K-bit serial E
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.

PROM,
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.
The X25138 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000
cycles and a minimum data retention of 100 years.
