IrDA controller LSIs | New product new technology

New Concept!Optical data exchange functionality makes it easy to use.ROHM LSI series - connect with ease(Wireless Data Transfer LSI Series)IrDA controller LSI

Although optical, wireless and wired communications methods each possess particular strengths, infrared communications is considered the most advantageous and can be easily installed.
	The communication method is optical, therefore no regulations exist, such as the Radio Law in Japan.

	Ensures worry free operation in public places, including hospitals and airports.

	The high degree of directivity makes it possible to specify the party you are communicating with.

	The use of mobile phones and other devices have become widespread, making the units easy to use.

	There is no need for connectors or external cords, so data can be transmitted easily.




ROHM’s IrDA controller LSIs feature a general-purpose CPU interface that allows virtually any CPU to be used, making it possible to add IrDA communication functionality to sets without worrying about the type of CPU.
