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 intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data 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 products.
