DESCRIPTION

The Microchip Technology Inc. 25AA040/25LC040/  
25C040 (25xx040 ) is a 4K bit serial Electrically Eras-

able PROM. 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. Also, write operations to the device can be  
disabled via the write protect pin (WP).  
*25xx040 is used in this document as a generic part number for the 25AA040/25LC040/25C040 devices.
