DESCRIPTION
The X25080 is a CMOS 8192-bit serial E
2
PROM,
internally organized as 1K x 8. The X25080 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 con-
trolled through a chip select (
CS
) input, allowing any
number of devices to share the same bus.
The X25080 also features two additional inputs that
provide the end user with added flexibility. By asserting
the
HOLD
input, the X25080 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 X25080 disabling all write attempts to the status
register, thus providing a mechanism for limiting end
user capability of altering 0, 1/4, 1/2 or all of the memory.
The X25080 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles
and a minimum data retention of 100 years.
