4K SPI Bus Serial EEPROM

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).

The Microchip Technology Inc. 25AA040/25LC040/

25C040 (25XX040^*) is a 4 Kbit serial Electrically

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.
