MCP212XDM

The MCP212XDM is a MCP2120/22 developer's board allows for the easy demonstration and development of IrDA applications. The board can be powered via USB or the power test points (VDD and GND). When using the power test points if JP2 is shorted the voltage must not exceed the PIC18F65J50 voltage specification. The preprogrammed PIC18F65J50 firmware generates the MCP2122's clock. The host interface can be connected to the UART driver device (for IrDA to UART operation) for communication over the DB 9 connector or connected to the PIC18F65J50 for stand alone operation. The USB interface signals are fully connected to the PIC18F65J50. So programs can be created where the PIC18F65J50 can communicate to the USB Host and to the MCP2122. This would allow the board to be used as an IrDA to USB converter.
