DESCRIPTION
The SigmaTel STIR4210 and STIR4220 are low power,
USB 2.0 Hi-Speed IrDA Bridge Controller integrated
circuits for enabling USB IrDA communication
solutions. The STIR4210/STIR4220 connect directly to
the USB Bus and provide all functionality necessary
between the USB 2.0 and an IR transceiver. A USB IR
communication subsystem can be implemented by
adding an IR transceiver, a 24 MHz crystal, and a few
passive components for bypass and power filtering.
The STIR4210/STIR4220 are compatible with the IrDA
Serial Infrared Physical Layer Specification Version 1.4.
The STIR4210 supports data rates up to 4 Mbits per
second (FIR) and the STIR4220 supports data rates up
to 16 Mbits per second (VFIR) including FIR. Both
devices support all of the lower data rates defined by
the IrDA specification (SIR and MIR).
The STIR4210/STIR4220 implement a USB 2.0
Hi-Speed device controller including integrated PHY/
transceivers, an IR Protocol Controller, a
programmable microcontroller, memory for program
and buffering, and voltage regulators required for the
typical USB based Infrared subsystem.
A high performance microcontroller provides control
functions. On-chip program ROM and program/data
RAM eliminates the need for external components.
RAM is used for data, buffering, and ROM patch.
The IR Protocol Controller supports the IrDA encode
and decode operations required by the various data
rates and allows the STIR4210/STIR4220 to interface
to a wide range of IR capable devices at the highest
performance. Unframed transfers are supported for
proprietary and remote control applications.
GPIO pins support the control of external functions.
These pins include an activity LED and pins for
transceiver ID. These pins can be used so that the
driver can detect which transceiver is used and
configure performance parameters if necessary. An
integrated PLL generates all on-chip clocks from a 24
MHz crystal. Integrated voltage regulators convert the
USB 5.0V power to 1.8V and 3.3V power required by
the device and the IrDA transceiver.
