IrDA Protocol Stack Handler

Wed, 02/27/2002 - 9:34am
Enhancing its Infrared product family, Microchip Technology introduced the MCP2155 IrDA® Protocol Stack Handler ideally suited for Data Communications Equipment (DCE) applications. The MCP2155 employs patented technology that embeds the complex IrDA protocol stack, including the Ir link access protocol (IrLAP), Ir link management-mux (IrLMP), tiny transport protocol (Tiny TP), IrComm layers (9-wire cooked service class) and portions of the IrPHY with bit encoding/decoding, into one peripheral device. Additionally, the MCP2155 provides ring indicate (RI), carrier detect (CD) and data terminal ready (DTR) signal information back to the primary as required in DCE applications.

The MCP2155, along with the MCP2150 embed the IrDA protocol stack handling plus bit encoding/decoding functionality into a small, low-cost form factor. This feature greatly simplifies the ability of a system designer to add IrDA standard wireless communication capability to their embedded systems, expanding the breadth of applications that can now easily add IrDA standard infrared communication.
