Introduction
1.2 Kit Overview
The Microchip maXTouch Curiosity Pro is an extension board for the Xplained Pro platform with a 320 x 480 RGB
LCD and a capacitive touch sensor with a maXTouch controller. The LCD can be controlled using different interfaces,
such as 3-wire and 4-wire SPI, Parallel, and RGB Parallel interface mode using the DIP switch to select the interface.
The maXTouch Curiosity Pro kit can be connected to any Curiosity boards or Xplained Pro standard extension
header, any curiosity Pro or Ultra kit, and many other Microchip MCUs using the 20-pin header, but is limited to 3-wire
and 4-wire SPI mode.
The maXTouch Curiosity Pro also features a standard LCD connector (FFC), which enables using the parallel
interfaces. Both connectors, FFC and 20-pin header, feature a SPI interface for the LCD and I2C for the maXTouch
device.

2. Overview
2.1 maXTouch® Capacitive Touchscreen Controller
The module touch screen interface is based on the Atmel maXTouch mXT336U Touch Controller and operates on the
touch sensor at connector J4. The touch controller scans the touch sensor and signals the host with an active-low
interrupt signal (~MXT_CHG on J2 & J3) when a new touch data is available. Data communication with the
maXTouch controller is performed over the I2C interface (on J2 & J3). The I2C address of the touch controller is fixed
at 0 x 4A, and is not configurable.
Note: The maXTouch has pull-up resistors on the I2C SCL (R17) and SDA (R16) lines. A pull-up resistor for the
maXTouch ~CHG interrupt signal is located at R18 (10k).
2.2 maXTouch® Controller Interface
Details of the maXTouch communication protocol are beyond the scope of this document. This module is pre-loaded
with a configuration already optimized for the maXTouch touch sensor and panel, hence the developer will only focus
on interfacing with the device. When developing the maXTouch controller interface during evaluation and host
development, care should be taken to avoid changing the maXTouch configuration or committing changes to NV
storage on the maXTouch controller. To start with host interface development, users need to leverage the existing
code available from MPLAB® Harmony, which is available at https://www.microchip.com/mplab/mplab-harmony.
For additional information regarding the maXTouch devices, refer to http://www.microchip.com.

3. Getting Started
This section covers getting started with Curiosity MCUs or Xplained Pro Quick Start.
Follow these steps to exploring the Microchip Curiosity Pro platform:
1. Download and launch MPLAB® X IDE.
2. Launch the plug-in manager and install MPLAB Harmony Code Configurator.
3. Connect the maXTouch Curiosity Pro to any Microchip Curiosity platform or Xplained Pro MCU board, and
connect a USB cable to the DEBUG USB port on the MCU board.
When the Curiosity MCU board or Xplained Pro MCU kit is connected to your computer for the first time, the
operating system will perform a driver software installation. The driver file supports 32-bit and 64-bit versions of
Microsoft® Windows® XP, Windows Vista®, Windows 7, Windows 8, and Windows 10.
After the Curiosity MCU board or Xplained Pro MCU board is powered, the green power LED will be lit and MPLAB X
IDE will auto detect which Curiosity MCU board or Xplained Pro MCU and extension boards are connected. MPLAB
X IDE will present relevant information, such as data sheets and kit documentation.
The target device is programmed and debugged by the on-board debugger, therefore no external programmer or
debugger tool is needed.
Getting Started
3.1 Connecting maXTouch Curiosity Pro to the Curiosity Board or Xplained Pro Board
Microchip maXTouch Curiosity Pro is designed to connect to the Curiosity board or Xplained Pro header marked
EXTx (x = 1 - 3). Refer to the pin out of the Curiosity MCU board or Xplained Pro evaluation kit to find out which
Xplained Pro EXT headers can be used. The FFC connector can be used if the parallel interface from the MCU to the
display is used on the kits featuring the graphical user interface. Any time only one cable must be connected.

Curiosity and Xplained Pro Boards
4. Curiosity and Xplained Pro Boards
The Curiosity boards and Xplained Pro boards are evaluation platforms that provide a full Microchip microcontroller
experience to users. This platform consists of a series of microcontrollers and extension boards, which are integrated
with MPLAB X IDE, MPLAB Harmony drivers, demo code, support data streaming, and so on.
The Curiosity boards or Xplained Pro boards support a wide range of Xplained Pro extension boards, which are
connected through a set of standardized headers and connectors. Each extension board has an identification (ID)
chip to uniquely identify which boards are connected to a Curiosity board or Xplained Pro board. This information is
used to present relevant user guides, application notes, data sheets, and example code through MPLAB X IDE.

4.2 maXTouch Parallel LCD Extension Connector
The LCD connector can be connected to display extensions that have a parallel interface. The connector implements
signals for an MCU parallel bus interface and a LCD controller interface, as well as signals for a touch controller. For
connector pin-out definition, refer to maXTouch parallel LCD Connector.

DS70005414B-page 6
Note: Usually only one display interface is implemented, either the LCD controller or the MCU bus interface. A FPC
or FFC connector with 50 pins and 0.5 mm pitch is used for the LCD connector.
4.3 Hardware Connection at J2
The FFC must be inserted with flex contacts facing down toward the PCB.

Microchip Devices Code Protection Feature
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.
