IrDA-Control Single-Chip Host Controller (HC)
IrDA-Control - A New IrDA® Standard for Wireless Command & Control Devices
GENERAL DESCRIPTION:
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

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.
FEATURES:
All-in-One Single-Chip Communication LSI (Encoder/Decoder, IrDA-Control MAC layer, HID LLC Layer, USB
protocol) that implements functions required for compliant IrDA-Control Host devices.
Optimized interface to Sharp IrDA-Control Infrared Transceiver (Sharp P/N: GP2W2001YK).
Optimized Direct Interface to External Serial EEPROM for address maintenance
12 MHz Single Phase Clock (Built-in Oscillation Circuit)
Manual Host Address configuration by DIP switch (recommended)
Pinouts provided for various LED indicators - NumLock / Caps Lock / Scroll Lock
Single Power Supply (5.0V)
APPLICATIONS
* Set-top Box for Cable / Satellite / Digital Terrestrial
* Entertainment / Multimedia Desktop PC
* Notebook PC
Broadcasting
* Internet TV / Interactive TV
