DESCRIPTION

The X25041 is a CMOS 4096-bit serial E

nally organized as 512 x 8. The X25041 features a Serial

Peripheral Interface (SPI) and software protocol allow-

ing 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 con-

trolled through a chip select (CS) input, allowing any

number of devices to share the same bus.

The X25041 also features two additional inputs that

provide the end user with added flexibility. By asserting

the HOLD input, the X25041 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 X25041 disabling all write attempts, thus providing

a mechanism for limiting end user capability of altering

the memory.

The X25041 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.
