General Description

The SCH5617 is a 3.3V PC 2001 compliant Super I/O controller with an LPC interface. All legacydrivers used for Super I/O components are supported making this interface transparent to thesupporting software. The LPC bus also supports power management, such as wake-up and sleepmodes.

The SCH5617 provides temperature monitoring with auto fan control. The temperature monitor iscapable of monitoring two external diodes, one internal ambient temperature sensor or retrievingtemperatures from external processors that implement the PECI Interface. This device offersprogrammable automatic fan control support based on one or more of these measured temperatures.There are three pulse width modulation (PWM) outputs with high frequency support as well as threefan tachometer inputs. In addition, there is support for a PROCHOT_IN# pin that may be used togenerate an interrupt, adjust the programmed temperature limits in the auto fan control logic, or forcethe PWM outputs on full. There is also a separate PROCHOT_OUT output pin. The RRCC featureprovides a linear relationship of temperature to fan speed.

The GLUE Logic includes various power management logic; including generation of RSMRST# andPower OK signal generation. There are also four LEDs to indicate power status and hard drive activity.Also included is SMBus Isolation logic, which can be used to isolate SMBus signals during power downmodes. The part also provides a low battery warning circuit.

SCH5617 provides 46 General Purpose I/O control pins, which offer flexibility to the system designer.There are 21 Scratchpad read/write runtime registers for custom use.

The SCH5617 incorporates the following Super I/O components: a parallel port that is compatible withIBM PC/AT architecture, as well as the IEEE 1284 EPP and ECP; two serial ports that are 16C550AUART compatible; one infrared port that is IrDA 1.0 compliant; a keyboard/mouse controller that usesan 8042 micro controller; floppy disk controller, which uses SMSC's true CMOS 765B core. The trueCMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures and issoftware and register compatible with SMSC's proprietary 82077AA core.

The SCH5617 is ACPI 1.0b/2.0 compatible supports multiple low power-down modes. It incorporatessophisticated power control circuitry (PCC), which includes keyboard and mouse wake-up events.

The SCH5617 supports the ISA Plug-and-Play Standard register set (Version 1.0a). The I/O Address,DMA Channel and hardware IRQ of each logical device in the SCH5617 may be reprogrammedthrough the internal configuration registers. There are up to 480 (960 for Standard Mode Parallel Port)I/O address location options, a Serialized IRQ interface, and four DMA channels.SMSC SCH5617 3 Revision 0.5 (05-29-07)PRODUCT PREVIEW
