FUNCTIONAL DIAGRAM
DESCRIPTION
The X25020 is a CMOS 2048-bit serial E
2
PROM, internally
organized as 256 x 8. The X25020 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 X25020 also features two additional inputs that
provide the end user with added flexibility. By asserting
the HOLD input, the X25020 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 X25020 disabling all write attempts, thus providing a
mechanism for limiting end user capability of altering the
memory.
The X25020 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.
