In focusing on connectivity solutions for our customers, Microchip now offers products to support infrared wireless communication. With the explosive growth of mobile phones, Personal Digital Assistants (PDAs) and other handheld electronic devices, the need for a simple, low cost wireless communication method has grown as well. The MCP2120 Infrared Encoder/Decoder is the first low-cost, easy-to-use infrared peripheral from a company that also has a broad range of microcontrollers and other related products specifically targeted for embedded systems. Utilizing this device and an off-the-shelf infrared transceiver, Microchip customers will now be able to add wireless communication capability to their designs. If interoperability with other infrared enabled devices is required in your design, Microchip again has your solution. The revolutionary MCP2150 and MCP2155 IrDA(R)protocol stack handler PLUS bit encoding/decoding devices are simply the smallest, and simplest way of adding IrDA functionality to embedded applications. In the past, supporting the complex IrDA protocol stack on the host microcontroller required a large amount of system resources and protocol stack knowledge. The MCP2150 and MCP2155 offload these requirements to a peripheral device, freeing up the system designer to focus on the design, not communication with the outside world. In addition to the MCP2150 and MCP2155, Microchip offers the MCP2140 Fixed Speed 9600 Baud IrDA Protocol Stack Controller for those high volume applications where costs are paramount. Additional benefits of the MCP2140 include an Automatic Low Power Mode, which keeps the device in a power-down state anytime there is no infrared activity. This function is ideal for minimizing current consumption and maximizing battery life. Applications include wireless handheld data acquisition systems, modems, printers, digital cameras, mobile telephones or peripherals, hotel locks, Point-of-Sale (POS) terminals, wireless user interfaces, or any other application where a cost-effective method of transferring data without a cable is desired.

The kit contains two MCP2120 developer's boards enabling a complete system (transmitter and receiver) to be implemented. Also included is an MCP2150 developer's board that can be used to set up a system to communicate with other IrDA(R)enabled devices. In addition, this MCP2150 developer's board can be easily modified to assist in developing DCE applications with the MCP2155. On these developer's boards, customers can configure input and output options. Input options include direct connection to a host UART or through on-board headers. Output options include an off-the-shelf transceiver and a minimal cost component solution that is jumper-selectable. All of this functionality is designed to get the user communicating via infrared in the shortest amount of time. Development Tools for Interface Products from Microchip
