Infrared communication is a low-cost method of providing wireless, point-to-point communication between two devices. The Infrared Data Association(IrDA) was formed in 1994 to develop standard methods for communicating over short-range infrared transmissions. These standards have continued to evolve and gain in popularity. Now, a wide variety of devices implement the IrDA standard specification, including computers, printers, PDAs, cell phones, watches and other instruments.

Microchip’s 16-bit microcontrollers are a perfect fit for applications wanting to support IrDA standard communication. These low-cost microcontrollers, with their built-in IrDA standard support, provide an inexpensive solution with plenty of computing power.
