DESCRIPTION

The Microchip Technology Inc. 25C080/160 are 8K and

16K bit Serial Electrically Erasable PROMs. The mem-

ory 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).
