Product Overview

The MCP2140A is a cost-effective, low pin count (18-pin), easy-to-use device for implementing IrDA standard wireless connectivity. It provides support for the IrDA standard protocol stack, bit encoding/decoding, and low-cost, discrete IR receiver circuitry. The MCP2140A is footprint compatible with the MCP2140. The serial and IR interface baud rates are fixed at 9600 baud. The MCP2140A will specify the IR baud rate to the primary device during the Discover phase. It can operate in Data Communication Equipment (DCE) and Data Terminal Equipment (DTE) applications, and resides between a UART and an infrared optical transceiver. The MCP2140A encodes an asynchronous serial data stream, converting each data bit to the corresponding infrared (IR) formatted pulse. IR pulses received are decoded and then handled by the protocol handler state machine. The protocol handler sends the appropriate data bytes to the host controller in UART formatted serial data. The MCP2140A supports "point-to-point" applications, that is, one primary device and one secondary device. It operates as a secondary device and does not support "multi-point" applications. The encoding/decoding functionality of the MCP2140A is designed to be compatible with the physical layer component of the IrDA standard, often referred to as "IrPHY".
