PIC18F STARTER KIT COMPONENT DESCRIPTIONS
Debug/Programmer Component
4.3.1
The components listed here (in order of their reference tags in Figure 4-3) are the key
components of the programmer/debugger side of the starter kit:
D1. PIC18F67J50 Microcontroller (U1): Controls the programming/debugging
D2. mini-B USB Receptacle (J2): Provides system power and bidirectional
D3. Debugger/Programmer Clock Crystal (Y1): Provides an accurate 12 MHz
D4. 25LC010A Serial EEPROM (U2): Store the starter kit’s serial number and
D5. Target Power LED (D2): When lit, indicates that power is being supplied to the
D6. Debug LED (D3): When lit, indicates that the starter kit is operating in
4.3.2
The components listed here (in order of their reference tags in Figure 4-3) are the key
components of the application side of the starter kit:
A1. PIC18F46J50 Microcontroller (U3): This provides the processing power for
A2. OLED Display (LED1): A 128 x 64 pixel, monochrome organic LED array
A3. MicroSD Card Socket (J5): A standard socket that is read and write compatible
operations of the target PIC18F46J50 microcontroller. It also provides the
12 MHz clock for the application side of the microcontroller.

operations in Programming and Debugging modes. The PIC18F67J50 also
uses this to generate a second 12 MHz clock for use by the PIC18F46J50
microcontroller.

the demo applications and application development on the starter kit. The micro-
controller features 64 Kbytes of Flash program memory and 3.7 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.)
