IrDA-Control / Product Information

"PRELIMINARY RELEASE"

, version 0.8, November, 1998

LZ8520X

IrDA-Control Single-Chip Host Controller (HC)

IrDA-Control - A New IrDA

Standard for Wireless Command & Control Devices

ENERAL

ESCRIPTION

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.
