F71612A
1. General Description
The F71612A is a USB IR chip and compatible for Microsoft Windows Vista and Windows 7 IR Receiver
or Transceiver Emulation Device. It Supports 2 IR transceiver functions for blaster application and two IR
receivers with long range frequency and wideband application.
In USB interface function, The F71612A 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/7 IR Receiver or Transceiver Emulation Device command and one input
endpoint is transmit IR information to host.
In I2C interface function, The F71612A builds 256 bytes SRAM to save flash/ROM information from I2C
for USB bus enumerations. The I2C flash/ROM contains IdVendor/ IdProduct/ BcdDevice/ Manufacturer
string / IProduct string / iSerialNumber string information.
In power function, the F71612A supports remote-wakeup function during USB interface, when PC
system into S3 state. The F71612A decodes IR protocol is the same power key of remote control. The
F71612A is asserted USB interface to wakeup PC system. Others also provide hardware pin PSOUT# for
system wakeup, when PC system in to S5 state, the F71612A is asserted PSOUT# pin to wakeup PC
system.
