DESCRIPTION  
Dec  
The Microchip Technology Inc. 25LC320 is a 32K-bit  
serial Electrically Erasable PROM (EEPROM). 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 exception of chip select, allowing the host  
to service higher priority interrupts. Also write opera-  
tions to the Status Register can be disabled via the  
write protect pin (WP).
