DLP-uCF4420 LEAD-FREE PPIICC1188FF44442200 TTAARRGGEETT BBOOAARRDD 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.) 2.0 SPECIFICATIONS Program Memory: 8K x 14 2.0-5.5V Operation** RAM Size: 768 x 8 31 I/O (13x10b Analog) EEPROM Size: 256 x 8 LED Indicator Size: 1.92 x 0.89 Inches **Note: If this target board is operated at a voltage other than 5.0 volts via a user-supplied power source, then the TPWR jumper must be removed on the DLP-FLASH2 Programmer. 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. Rev. 1.1 (September 2007) 1 DLP Design, Inc. 4.0 PROGRAMMER/DEBUGGER INTERFACE The DLP-FLASH2 Programmer/Debugger utilizes a 6-pin, 2mm female header for connection to the target device.
