MTCH6301
MTCH6301 Projected Capacitive Touch Controller
Summary
Power Management
The MTCH6301 is a turnkey projected capacitive touch
controller that allows easy integration of multitouch and
gestures to create a rich user interface in your design.
Through a sophisticated combination of Self and
Mutual Capacitive scanning for both XY screens or
touch pads, the MTCH6301 allows designers to quickly
and easily integrate projected capacitive touch into
their application.
• Configurable Sleep mode
• Integrated Power-on Reset and Brown-out Reset
• 20 µA sleep current (typical)
A new Projected Capacitive Configuration Utility with
an autotune feature allows fast customization for
different sizes and top layer thicknesses.
For further customization, designers can also get
access to the firmware library to optimize and improve
designs as needed.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
