SMSC SIO1049
LPC Media Center Consumer IR Controller with Windows

Remote Control Support
General Description
SMSC’s SIO1049 is the industry's first Consumer Infrared (CIR) transceiver solution and Super I/O
Controller designed specifically to support the latest Microsoft
®
Vista
TM
operating system features
available in Premier and Ultimate Home versions, with native Microsoft drivers. Integrating the CIR
functions in the SIO1049 on the motherboard eliminates the need for an external USB dongle, offering
a greater than 50% cost savings, while adding features: especially ACPI 2.0 compliant CIR integration.
The CIR port is fully backward compatible and supports NEC, Philips RC5 and Microsoft CIR protocols
in hardware for waking from any low power state (S3, S4 and S5) or seamlessly placing the system
into a low power state. The SIO1049 also supports all other CIR protocols in software for normal data
transfer via a wide-band receiver block, known as "Learn Mode". A third block is provided in order to
be able to transmit learned IR control codes on up to four IR emitter ports, for control of set-top boxes
and/or other media equipment.
There is an additional dedicated Infrared networking interface, which complies with IrDA v1.2 (FIR, MIR
and SIR), HPSIR, and ASKIR formats (used by Sharp and other PDAs).
The SIO1049 also:
Incorporates a 16C550A compatible UART and one Multi-Mode parallel port with SMSC’s
ChiProtect(tm) circuitry. The parallel port is compatible with IBM PC/AT architectures, as well as
IEEE 1284 EPP and ECP. The parallel port ChiProtect circuitry prevents damage caused by an
attached powered printer when the SIO1049 is not powered. The SIO1049 also includes Software
Configurable Logic (SCL) for ease of use. SCL allows programmable system configuration of key
functions such as the parallel port and UART.
Does not require any external filter components, is easy to use and offers low system cost and
reduced board area benefits with its small 7x7 mm STQFP package. It is optimized for complete
system integration on a desktop or notebook motherboard.
Offers a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI CLKRUN#
support, relocatable configuration ports, and three DMA channel options.
Supports the ISA Plug-and-Play Standard register set (Version 1.0a). The I/O Base Address, DMA
Channel, and Hardware IRQ of each device in the SIO1049 may be reprogrammed through the
internal configuration registers. There are multiple I/O address location options, a Serialized IRQ
interface and three DMA channels.
Communicates with x86-based chipsets through the LPC interface and includes 14 dedicated GPIO
pins.
