The MCP2155 is a cost effective, low pin count (18-pin), easy to use device for implementing IrDA standard wireless connectivity. The MCP2155 handles for the IrDA standard protocol “stack” plus bit encoding/decoding. The MCP2155 operates in Data Communication Equipment (DCE) applications and sits between a UART and an infrared optical transceiver.The Serial interface baud rates are user selectable to one of four IrDA standard baud rates between 9600 baud and 115.2 kbaud (9600, 19200, 57600, 115200). The IR
