MTCH6301
Summary
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.
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.

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
