MCP2140DM-TMPSNS

The MCP2140DM-TMPSNS is a MCP2140 IrDA wireless temperature demo board, demonstrates the MCP2140 device in a real world application. The MCP2140 is a cost effective, low pin count (18 pin), easy to use device for implementing IrDA standard wireless connectivity. The MCP2140 provides support for the IrDA standard protocol stack, bit encoding/decoding and low cost, discrete IR receiver circuitry. The serial and IR interface baud rates are fixed at 9600 baud. The serial interface and IR interface baud rates are dependent on the device frequency, but IrDA standard operation requires a device frequency of 7.3728MHz. The MCP2140 IrDA standard wireless temperature sensor demo board is used to evaluate and demonstrate the MCP2140 device in a data logging application by transmitting ambient temperature to a PDA (e.g Palm PDA) or laptop computer. It is intended to serve as an example to assist system designers in developing an IrDA standard node using the MCP2140 device.
