Microchip Technology's MCP2155 IrDA Protocol Stack Handler has been released, targeting Data Communications Equipment (DCE) applications.

The MCP2155 uses 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 that Microchip announced in June, 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 system designers 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.

The MCP2155, which connects to standard microcontroller UART peripherals and infrared transceivers, finds applications in a variety of markets, such as telecommunication, consumer, industrial, medical, and automotive.

Microchip also offers the Infrared Products Developer's Kit to assist designers with demonstration and development of IrDA-enabled applications, including everything they need to create systems employing infrared communication.

Microchip designs, develops, and manufactures a broad range of microcontrollers and other related products targeted for embedded control systems. This infrared product family offers Microchip microcontroller customers an easy way to add infrared connectivity to their existing designs enabling wireless data transfer capability.

The MCP2155 is available in 20-pin SSOP, 18-pin PDIP, and SOIC packages with pricing starting at $5.47 each in 1,000 piece quantities. Samples and development tool support are available immediately for these devices.
