Switch Monitor Interface
The 33884 Switch Monitor Interface is a monolithic silicon integrated
circuit (IC) to perform switch monitoring functions. The device provides
efficient interface between electrical switches and low voltage
microprocessors. The 33884 supplies switch contact pull-up and pull
down current while monitoring the input voltage level. All inputs are
protected for transients when implemented with an appropriate static
discharge capacitor used on the inputs.
There are four modes of operation: Sleep, Normal, Polling, and
Polling + INT Timer.
The Polling and Timer modes are similar, except the Timer mode
has the addition of an interrupt that is sent to the microprocessor if a
switch is sensed
closed,
or upon the internal interrupt timer
times out
.
An interrupt is ultimately sent to the microprocessor. All modes of
operation are easily programmed via the Serial Peripheral Interface
(SPI) control.
