27.0 CAPACITIVE SENSING (CPS)
MODULE
The Capacitive Sensing (CPS) module allows for an
interaction with an end user without a mechanical
interface. In a typical application, the CPS module is
attached to a pad on a Printed Circuit Board (PCB),
which is electrically isolated from the end user. When the
end user places their finger over the PCB pad, a
capacitive load is added, causing a frequency shift in the
CPS module. The CPS module requires software and at
least one timer resource to determine the change in
frequency. Key features of this module include:
Analog MUX for monitoring multiple inputs
Capacitive sensing oscillator
Multiple Power modes
High-power range with variable voltage references
Multiple timer resources
Software control
Operation during Sleep
