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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Chapter 1. MTCH101 Evaluation Kit Overview
1.1
INTRODUCTION
The MTCH101 Evaluation Kit is one of the quickest ways to implement and start
evaluating Microchip’s mTouch™ technology with minimum effort. The MTCH101
controller and the evaluation board feature a single-channel input which handles one
Capacitive Touch Input sensor. The controller and the board can be used as a
companion chip reporting back to a host system, although the evaluation board
functions in complete autonomy and provides Touch feedback using an LED.
1.1.1
Kit Contents
• MTCH101 Controller Board
• MTCH101 Proximity Sensor Board
• Mini to USB-B Cable
1.2
HARDWARE SETUP
The MTCH101 Evaluation Kit includes the controller board onto which the MTCH101
chip is implemented, as well as a Proximity Sensor daughter board. The kit can also
handle sensors to be used as buttons.

MTCH101 EVALUATION KIT BOARDS
DS40001774A-page 9
MTCH101 Evaluation Kit User’s Guide
1.2.1
MTCH101 Proximity Sensor Board
The Proximity Sensor board needs to be connected to the main controller board in
order to get a fully functional Touch Input system.
FIGURE 1-2:
MTCH101 PROXIMITY SENSOR BOARD
Users can connect their own sensor to the main board by using pin 2 of the header
connector located to the right of the MTCH101 chip, labeled U1 on the board. The
header connector also provides an optional Ground output on pin 4.
1.2.2
MTCH101 Controller Board
FIGURE 1-3:
MTCH101 CONTROLLER BOARD
Figure 1-3 shows the Controller board with the MTCH101 chip (U1 Chip on board). It
is responsible for the touch event detection, its processing, and its output by lighting
the red LED (D1). It expects a capacitive touch sensor on the female 12-pin header
connector to the right of the chip. The Proximity sensor board included in the package
can be connected or the user can connect one sensor to pin 2 of the 12-pin header
connector.
1.2.2.1
POWER-UP
To the left of the U1 chip is the mini-USB connector (J1) used to power the controller
board. This connector only provides voltage (5V) to the board. It is not used for any
communications.

MTCH101 Evaluation Kit Overview
1.2.2.2
TOUCH SENSITIVITY ADJUSTMENT
At the top of the controller board, a potentiometer (MTSA Label) allows alteration to the
sensitivity of the Touch or Proximity sensor. This directly affects the voltage of MTSA
input of the MTCH101 controller. For further information on Sensitivity Adjustment,
please refer to the MTCH101 data sheet (DS40001664).
1.2.2.3
POWER CONSUMPTION MANAGEMENT
The MTCH101 controller provides a way to manage two working modes with different
power consumption options for the system. These modes are called Normal and
Low-Power. They are selected by input pin MTPM of the MTCH101 controller.
When powered, by default the board sets the controller to work in Normal mode by
applying a high level to the MTPM pin. The user can select the Low-Power mode by
shorting the two headers labeled ‘MTPM Low’ at the bottom-right part of the controller
board. Disconnecting the headers returns the board to a ‘Normal’ working mode and
consumption.
1.2.2.4
INPUT INTERFACE
The MTCH101 controller board uses pin 2 of the 12-pin header connector to detect
Touch or Proximity events from a sensor. This input is connected to the MTI pin of the
MTCH101 controller through a 4.7K resistor. This allows a sensor to be directly
connected to the board.
1.2.2.5
EVENT OUTPUT INTERFACE
The MTCH101 controller uses its MTO pin to transmit a Touch or Proximity event to a
host. The MTCH101 Controller board uses this output to light up the red LED,
whenever a Touch or Proximity event is detected.
