IrDA-Control / Product Information

LZ8520X

IrDA-Control Single-Chip Host Controller (HC)

IrDA-Control - A New IrDA

The Sharp IrDA-Control Host

Controller (HC) is a single-chip

communication LSI with built-in

USB protocol and IrDA-Control

protocol (MAC Layer and HID LLC

Layer) services. When combined

with a Sharp IrDA-Control

transceiver (Sharp P/N:

GP2W2001YK), an IrDA-Control

Host device can be easily

implemented. The PC will

immediately perform as an IrDA-

Control Host device by connecting

the implemented Host to the PC by a

USB interface. The IrDA-Control

Host device is able to maintain

simultaneous multiple wireless links with up to 8 IrDA-Control Peripheral devices. In combination with BIOS that supports

USB keyboards in the market place, the Sharp HC will enable wireless links between IrDA-Control mouse and keyboard

under DOS mode. For the IrDA-Control Peripheral implementation, Sharp also offers the IrDA-Control Peripheral Engine

(PE, Sharp P/N: LZ8519X) as well as transceivers (Sharp P/N: GP2W2001YK/2002YK) as a complete solution for this

technology.

protocol) that implements functions required for compliant IrDA-Control Host devices.
