DESCRIPTION

The X25650 is a CMOS 65,536-bit serial EEPROM,

internally organized as 8K x 8. The X25650 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.

The X25650 also features two additional inputs that pro-

vide the end user with added ﬂexibility. By asserting the

HOLD input, the X25650 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 X25650 disabling all write attempts to the status

capability of altering 0, 1/4, 1/2 or all of the memory.

The X25650 utilizes Xicor’s proprietary Direct Write

cell, providing a minimum endurance of 1,000,000

cycles and a minimum data retention of 100 years.
