DESCRIPTION
The Microchip Technology Inc. 25LC080/160 are 8K
and 16K bit Serial Electrically Erasable PROMs. The
memory 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 鏗俥xibility. 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).
