Applications

The MCP2150 Infrared Communications Controller

supporting the IrDA standard provides embedded sys-

tem designers the easiest way to implement IrDA stan-

dard wireless connectivity. Figure 1-1 shows a typical

application block diagram. Table 1-2 shows the pin

definitions.

TABLE 1-1:

OVERVIEW OF FEATURES

Infrared communication is a wireless two-way data

connection, using infrared light generated by low-cost

transceiver signaling technology. This provides reliable

communication between two devices.

Infrared technology offers:

• Universal standard for connecting portable

computing devices

• Easy, effortless implementation

• Economical alternative to other connectivity

solutions

• Reliable, high-speed connection

• Safe to use in any environment (can even be

used during air travel)

• Eliminates the hassle of cables

• Allows PCs and other electronic devices (such as

PDAs, cell phones, etc.) to communicate with

each other

• Enhances mobility by allowing users to easily

connect

The MCP2150 allows the easy addition of IrDA stan-

dard wireless connectivity to any embedded applica-

tion that uses serial data. Figure 1-1 shows typical

implementation of the MCP2150 in an embedded

system.

The IrDA protocols for printer support are not included

in the IrCOMM 9-wire “cooked” service class.
