Microchip | MCP2155-I/SS

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 protocal stack plus bit encoding/decoding. The MCP2155 operates in Data Communication Equipment(DCE) applications and sits betweeen a UART and abn infrared optical transceiver.

The serial interface baud rates are user electable to one of four IrDA standard baud rates between 9600 baud and 115.2 kbaud (9600, 19200, 57600, 115200). The IR baud rates are user selectable to one of five IrDA standard baud rates between 9600 baud and 115.2 kbaud (9600, 19200, 37400, 57600, 115200). The serial interface baud rate will be specified by the BAUD1:BAUD0 pins, while the IR baud rate is specified by the Primary Device (during Discover phase). This means that the baud rates do not need to be the same. The MCP2155 operates in Data Terminal Equipment (DTE) applications and sits between a UART and an infrared optical transceiver.

Features:

• Supports the IrComm (9-wire cooked service class), TinyTP, IrLMP, IrLAP layers of the IrDA
• Standard protocol stack and portions of the IrPHY layer including bit encoding/decoding.
