6. Function Description
6.1 USB function
The F71610 communications with host by full-speed USB interface (12Mb/s). It supports 3 suits
endpoint, one control endpoint( endpoint zero) is for bus enumeration, one output endpoint is for
Microsoft Windows Vista IR Receiver Emulation Device command and one input endpoint is transmit
IR information to host.
Endpoint zero is special significance in USB system. It is a control endpoint, and is required by
every device. Only control endpoint accept special setup token that the host transfer command to
device.
During enumeration, host requests GET_DESCRIPTOR to device and device return information
(over in endpoint zero) as what device driver top load. The below table is about F71610 descriptor.

Table 6-5 Out Endpoint Descriptor
The string table 1 is about manufacturer information, its’ contents is “FINTEK”, the string table 2
is about Product information, its contents is “eHome Infrared Transceiver. The string table 3 is about
serial number information, its contents is “88636562727801”.
In power function, The F71610 supports remote-wakeup function for USB interface, when PC
system into S3 state. The F71610 decodes IR protocol is the same power key of remote control. The
F71610 is asserted USB interface to wakeup PC system.
The F71610 is compatible for Microsoft Windows Vista IR Receiver Emulation Device. The
F71610 support Microsoft Compatible Device Descriptor and Extended Compact ID Descriptor are
used to tell the host what type of device the emulation is. Vista Emulation Device driver transmits
command over out endpoint1 and device return information over in endpoint1. About descriptor and
command information, reference Microsoft Windows Vista IR Receiver Emulation Device spec.

F71610
The F71610 supports One IR receiver with long range frequency application. The long-range
receiver is a receiver which has the following characteristics:
1. Works at a distance of 10 meters.
2. Demodulates the signal inside the receiver part
3. Has a BPF which works with carriers from 32-60 kHz.
About IR information, reference Microsoft Windows Vista IR Receiver Emulation Device spec.
6.3 Wakeup function
The F71610 Supports 2 kinds of wakeup system function, PSOUT and remote wakeup for USB
interface. The F71610 detect idle state on USB bus for more than 3.0ms, it is into suspend state.
In Suspend state, the F71610 decodes IR protocol information is the same power key of
remote controller. It asserted PSOUT and USB interface. Reference the below figure

6.4 I2C interface function
The F71610 Supports 1 suit I2C interface to get USB description information and builds 256
bytes RAM to save vendor USB description information. When power is ready, I2C function start to
load USB description into 256 bytes RAM, and expect host requests GET_DESCRIPTOR to F71610
which returns vendor USB description, if i2c flash/ROM connect with F71610. The contents of I2C
flash /ROM format is below table.
When F71610 does not finish loading 256 bytes information from I2C flash/ROM, F71610
disable PAD 1 internal pull high 1.5k, still finish loading, F71610 enable PAD 1 internal pull high 1.5k.
