The capacitive sensing modules (CSM) allow for an
interaction with an end user without a mechanical
interface. In a typical application, the capacitive
sensing 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 capacitive sensing module. The
capacitive sensing 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
• Multiple timer resources
