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 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).
