Product Information

In focusing on connectivity solutions for our customers,
Microchip now offers products to suppor t 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 low­cost, 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. The
MCP2120 enables customers to add infrared wireless
communication capability to their embedded systems by a
simple connection to a micro-controller UART peripheral
on one end and an infrared transceiver at the other end.

If interoperability with other infrared enabled devices is
required in your design, Microchip again has your
solution. The revolutionary MCP2150 Infrared
Communications Controller supporting the IrDA®Standard
is simply the smallest, simplest, most economical way of
adding IrDA cordless connectivity to embedded
applications. In the past, supporting the complex IrDA
Standard protocol stack on the host microcontroller
required a large amount of system resources and protocol
stack knowledge. The MCP2150 off-loads these
requirements to a peripheral device, freeing up the
system designer to focus on the design, not the
communication with the outside world.

Applications for these infrared communication products
include application-specific PCs and specialty peripherals,
and wireless handheld data acquisition systems in the
industrial market, pagers and modems in the
communications market, POS terminals, printers and
digital cameras in the consumer market, and fleet
management systems in the automotive market. Any
application where a cost-effective method of transferring
data without a cable is the desired, Microchip has the
solution.

Development Tool Support

The MCP2120/MCP2150 Infrared Developer Kit includes everything needed to create a system that communicates using
infrared. The kit contains two MCP2120 developer boards enabling a complete system (transmitter and receiver) to be
implemented. Also included is an MCP2150 developer board that can be used to set up a system to communicate with
other devices that contain the IrDA feature. On these developer 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 of f-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.
