IrDA Control Host Controller with USB Interface User’s Guide

General Description
The Sharp IrDA Control Host Controller with USB I/F
1
(HC, SHARP P/N: LZ85202) is a
communication controller with USB interface that fully supports IrDA Control communica-
tion services
2
. Using the HC in conjunction with the Sharp IrDA Control Infrared Transceiver
(P/N: GP2W2001YK), USB transceiver LSI, and serial EEPROM will implement an IrDA
Control Host device, to which up to eight wireless peripherals, such as mice and keyboards
in PC environment, can be connected for comfortable wireless operation environment.
NOTES:
1. IrDA Control Host Controller with USB I/F represents ‘USB dongle controller for IrDA control host imple-
mentation’. USB dongle is an external adapter (hardware) and can be connected to the external USB port
of specific products, with which a new interface (IrDA interface) can be provided.
2. IrDA Control Specification (formerly IrBus) IrDA CIR (Control IR) Standard Final Specification, Final Revi-
sion 1.0, June 30,1998 (http://www.irda.org).
HC Features
Equipped with USB I/F to interface with PC.
All required functions for IrDA Control communication, Media Access Control (MAC)
layer, Human Input Device (HID LLC) layer, IrDA Control to USB Bridge layer, and USB
Controller are embedded in the HC.
Optimized interface to Sharp IrDA Control Infrared Transceiver
(SHARP P/N: GP2W2001YK).
Optimized interface to USB transceiver LSI (P/N: PDIUSBP11A by PHILIPS, tolerant
shifter required).
Conforms to EP0, EP1, EP2 (for future extension), and EP3 as an IrDA Control Endpoint.
A single HC supports maximum of eight wireless links with IrDA Control Peripherals.
Figure 1 shows the HC interface signals. The HC signal lines are generally categorized to
two types; interface signals with IrDA Control infrared transceiver, and USB interface sig-
nals for USB transceiver.
