DESCRIPTION
The Microchip Technology Inc. 25AA160/25LC160/
25C160 (25XX160
*
) are 16 Kbit Serial Electrically
Erasable PROMs. The memory is accessed via a sim-
ple 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.
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.
