DESCRIPTION
The X25170 is a CMOS 16384-bit serial E2PROM, inter-
nally organized as 2K x 8. The X25170 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 X25170 also features two additional inputs that pro-
vide the end user with added flexibility. By asserting the
HOLD input, the X25170 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 X25170 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 X25170 utilizes Xicor’s proprietary Direct Write cell,
providing a minimum endurance of 100,000 cycles and a
minimum data retention of 100 years.
