DESCRIPTION

The Microchip Technology Inc. 25AA320 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 the exception of chip select, allowing the

host to service higher priority interrupts. Also, write

operations to the Status Register can be disabled via

the write protect pin (WP).

SPI is a trademark of Motorola.
