5.3.1 Programmer/Debugger Components

The components listed here (in order of their reference tags in Figure 5-3) are the key

components of the programmer/debugger side of the starter kit:

D1. mini-B USB Receptacle (J1): Provides system power and bidirectional

communication between the host PC and starter kit.

D2. PIC18F67J50 Microcontroller (U2): Controls the programming/debugging

operations of the target PIC24FJ256GB106 microcontroller. It also provides the

12 MHz clock for the PIC24F microcontroller.

D3. MCP1727 Voltage Regulator (U1): The 3.3V linear regulator regulates the USB

unregulated voltage to 3.3 volts (with respect to V

SS) and supplies the starter kit

with system power.

D4. Target Power LED (D4): When lit, indicates that power is being supplied to the

application side of the starter kit from V

BUS (either from a USB connection or from

the V

BUS test point).
