DESCRIPTION
The Microchip Technology Inc. 25LC320 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 exibility. 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 exception of chip select, allowing the host
to service higher priority interrupts. Also write opera-
tions to the Status Register can be disabled via the
write protect pin (WP).
