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).

The Microchip Technology Inc. 25AA040/25LC040/
25C040 (25XX040 * ) is a 4 Kbit serial Electrically
Latches
Erasable 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.
*25XX040 is used in this document as a generic part number
for the 25AA040/25LC040/25C040 devices.
