DESCRIPTION
The X25C02 is a CMOS 2048-bit serial E
2
PROM, inter-
nally organized as 256 x 8. The X25C02 features a serial
interface 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 X25C02 also features two additional inputs that
provide the end user with added flexibility. By asserting
the
HOLD
input, the X25C02 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 X25C02 disabling all write attempts, thus provid-
ing a mechanism for limiting end user capability of
altering the memory.
The X25C02 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.
