DLP-uCF4420
LEAD-FREE
PIC18F4420 TARGET BOARD
1.0 INTRODUCTION
The DLP-uCF4420 Target Board is designed to easily connect to the DLP-FLASH2 Device
Programmer/Debugger and provide the design engineer with a low-cost hardware platform for
developing and testing applications for the PIC18F4420 microcontroller.
(Refer to the schematic at the end of this datasheet for additional details.)

3.0 OSCILLATOR OPTIONS
The PIC18F4420 has an internal oscillator with eight user-selectable frequencies from 31 kHz to
8 MHz. The internal oscillator also provides a range of clock speeds from 31 kHz to 32 MHz when
used with the PLL. Refer to the datasheet for the PIC18F4420 for additional details.
A user-supplied crystal and associated capacitors can also be added if a specific operating frequency
is required.
