The IRC1802 is a low-cost, highly integrated SIR, MIR, FIR and Very Fast Infrared (VFIR) communications controller capable of supporting IrDA 1.x infrared modulation schemes including HPSIR and Sharp ASK. The IrDA 1.x low and high-speed communication modes support all speeds up to 16 Mb/s (VFIR). All speeds can use Direct Memory Access.

The same drivers of the IRC1802 are used for all speeds for receiving and transmitting, simplifying driver programming and speed upgrades. Typical applications include data transfer in notebook computers, desktops computers, printers, access-points, digital cameras and peer-peer or client-server network environments.
