BOARD COMPONENTS
4.2.1
The components listed here (in order of their reference tags in Figure 4-3) are the key
components of the application side of the CAP TOUCH – CTMU Evaluation Board:
1. PIC24FJ128GB106 Microcontroller (U1): This provides the processing power
2. USB mini-B Receptacle (J3): This provides a convenient interface to the PC
3. ICSP™ Programming Header (J1): This provides a standard Microchip ICD
4. Power Supply (Q1): This converts the +5 V
5. Plug-in Sensor LEDs (D1-D16): Sixteen LEDs (D1 through D16) are connected
6. Plug-in Interface Connector (J4): This is a 48-pin connector, which is used to
7. External Plug-in Components:
- Matrix Key Plug-in Board: The Matrix Key Plug-in board is an array of
for the touch sense demo applications. The microcontroller features 64 Kbytes
of Flash program memory and 16 Kbytes RAM, allowing sufficient space for the
development of more complex touch sense applications.
The demo application uses an 8 MHz signal to create the 48 MHz USB clock, as
well as the application’s 32 MHz clock. Crystal, Y1, and associated components
are used by the microcontroller’s internal oscillator to maintain the frequency
tolerances required by the USB specifications.
side of the demo application. As the CAP TOUCH – CTMU Evaluation Board
functions as a bus-powered device, this connection also provides power to the
board.
interface for programming and debugging applications on the CAP TOUCH –
CTMU Evaluation Board. It is designed to connect directly with Microchip’s
PICkit™ Starter Kit. Pin 1 (N/C) is located on the right side of the interface, as
viewed from the front of the board, and is marked with an arrow.

interface the different plug-in boards to the microcontroller. This connector is
interfaced to 16 analog channels of the microcontroller and the remaining pins
are connected to ground of the CAP TOUCH – CTMU Evaluation Board.
- Direct Key Plug-in Board: The Direct Key Plug-in board comprises
12 touch-sensitive keys arranged in a 4x3 matrix. The plug-in also com-
prises a 24-pin connector (12-pin x 2) to connect to the evaluation boards.
8 touch-sensitive keys and a 24-pin connector (12-pin x 2), which can be
interfaced to any of the 8 channels of the connector (J4) provided in the
evaluation boards.
