The components listed here (in order of their reference tags in Figure 5-3) are the key
components of the application side of the starter kit:
A1. PIC24F256GB106 Microcontroller (U6): This provides the processing power
A2. Tri-Color LED Pads (D6, D10 or D11): One of these locations is populated with
A3. OLED Display (LED1): A 128 x 64 pixel, monochrome organic LED array
A4. Capacitive Touch Pad (S1): This 5-element keypad is an integral part of the
A5. RTCC Crystal (Y2): Provides an accurate 32.768 kHz reference for the micro-
A6. USB A Receptacle (J4): The application uses this receptacle to connect with
A7. Mini-B USB Receptacle (J5): Physically identical to J1, this provides USB con-
A8. Potentiometer (R44): Provides an analog input to the microcontroller for certain

frequency reference for the PIC18F67J50 microcontroller for stable USB
operations in Programming and Debugging modes. The PIC18F67J50 also uses
this to generate a second 12 MHz clock for use by the PIC24FJ256GB106
microcontroller.

for the demo applications and application development on the starter kit.
The microcontroller features 256 Kbytes of Flash program memory and
16 Kbytes RAM.
The demo application uses an external 12 MHz signal from the programmer side
as clock source. Custom applications that do not use the USB module may also
use the microcontroller’s on-chip FRC oscillator as a clock source. (USB appli-
cations must use the 12 MHz programmer clock source, as the tolerance of the
FRC oscillator exceeds USB specifications.)

availability of components at the time of the board’s assembly. Functionally, the
LEDs at any of these sites are interchangeable.

direct contact with the user by monitoring each of the touch pad’s elements with
the microcontroller’s integrated CTMU module.
