DESCRIPTION
The Microchip Technology Inc. 25C080/160 are 8K and
16K bit Serial Electrically Erasable PROMs. The mem-
ory is accessed via a simple Serial Peripheral Interface
(SPI) compatible serial bus. The bus signals required
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.
There are two other inputs that provide the end user
with additional flexibility. Communication to the device
can be paused via the hold pin (HOLD). While the
device is paused, transitions on its inputs will be
ignored, with the exception of chip select, allowing the
host to service higher priority interrupts. Also write
operations to the Status Register can be disabled via
the write protect pin (WP).
