DESCRIPTION  
The Microchip Technology Inc. 25AA160/25LC160/  
25C160 (25XX160*) are 16K bit serial Electrically Eras-  
able 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.  
Communication to the device can be paused via the  
hold pin (HOLD). While the device is paused, transi-  
tions on its inputs will be ignored, with the exception of  
chip select, allowing the host to service higher priority  
interrupts.  
*25XX160 is used in this document as a generic part number for the 25AA160/25LC160/25C160 devices.  
SPI is a trademark of Motorola.
