The PIC18 Wireless Development Board supports the XLP microcontroller options
such as PIC18F46J11, PIC18F46J50, PIC18F46K20 and PIC18LF45K22.
The default microcontroller option is PIC18F46J50. Different microcontroller options
require different components to populate on the PIC18 Wireless Development Board.
The following main blocks are defined on the Board:
• Serial Accessory Port
• USB Interface Port
• PICtail Port
• Push Buttons
• Onboard Temperature Sensor
• Onboard Serial EEPROM
• Debug LEDs
• Power Supply
2.1.1 Serial Accessory Port
Serial Accessory Port provides a simple serial interface for the external modules.
These modules may be either external sensor or accessory board. For more
information about existing accessory boards refer to the
http://www.microchip.com or
“LCD Serial Accessory Board User’s Guide” (DS70650) or “RS232 Serial Accessory
Board User’s Guide” (DS70649).
The following interfaces are supported by the Serial Accessory Port:
• 3 or 4 wire SPI
•I
2
C™
• USART
These interfaces are selected by the software without modifying the hardware. User
should be attentive when different interfaces use the same hardware or share the same
port pins of the microcontroller. For more information on the port pin assignment, see
Figure A-1.
2.1.2 USB Interface Port
The PIC18F46J50 microcontroller provides USB v2.0 compliant full-speed Universal
Serial Bus (USB) interface, which helps suppling power to the PIC18 Wireless
Development Board. The relevant USB components are included with the
PIC18F46J50 microcontroller option.
Note 1: Missing components on the PIC18 Wireless Development Board does
not indicate a defect. Population of these missing components depend on
the Microcontroller being used. For more information about using
different Microcontrollers, see the Section A.2 “PIC18 Wireless
Development Board Schematic”.
2: Take precautionary measure while changing the microcontroller option as
improper tools or poor handling could harm the copper tracks on the
surface of the Board, it might destroy it.
