Protocol Stack Controller
The MCP2140 is a fixed speed 9600-Baud IrDA-Standard protocol stack controller. When used with the recommended discrete transceiver implementation, this device enables a complete IrDA-Standard wireless link (protocol handling plus transceiver) to be added to an embedded system while typically consuming less than 100 μA of additional current. The MCP2140 has an automatic low-power function that reduces the power consumption when there is no activity on the link.
