Desktop System Controller Hub with Advanced, 8051µC-Based Auto Fan Control PRODUCT PREVIEW General Description The SCH5617 is a 3.3V PC 2001 compliant Super I/O controller with an LPC interf ace. All legacy drivers used for Super I/O components are support ed making this interface transparent to the supporting software. The LPC bus also supports power management, such as wake-up and sleep modes. The SCH5617 provides temperature monitoring with auto fan control. The temperature monitor is capable of monitoring two external diodes, one inte rnal ambient temperatur e sensor or retrieving temperatures from external processors that implement the PECI Interface. This device offers programmable automatic fan control support based on one or more of thes e measured temperatures. There are three pulse width modulation (PWM) outputs with high frequency support as well as three fan tachometer inputs. In addition, there is support for a PROCHOT_IN# pin that may be used to generate an interrupt, adjust the programmed temperature limits in the auto fan control logic, or force the PWM outputs on full. There is also a sepa rate PROCHOT_OUT output pin. The RRCC feature provides a linear relationship of temperature to fan speed. The GLUE Logic includes various power manageme nt logic; including generation of RSMRST# and Power 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 down modes. The part also provides a low battery warning circuit. SCH5617 provides 46 Gene ral Purpose I/O control pins, which offe r flexibility to the system designer. There are 21 Scratchpad read/write runtime registers for custom use. The SCH5617 incorporates the following Super I/O com ponents: a parallel port that is compatible with IBM PC/AT architecture, as well as the IEEE 1284 EPP and ECP; two serial ports that are 16C550A UART compatible; one infrared port that is IrDA 1.0 compliant; a keyboard/m ouse controller that uses an 8042 micro controller; floppy disk controller, wh ich uses SMSC's true CMOS 765B core. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures and is software and register compatible with SMSC's proprietary 82077AA core. The SCH5617 is ACPI 1.0b/2.0 compatible support s multiple low power-down modes. It incorporates sophisticated power control circuitry (PCC), wh ich includes keyboard and mouse wake-up events. The SCH5617 supports the ISA Plug- and-Play Standard register set (V ersion 1.0a). The I/O Address, DMA Channel and hardware IRQ of each logica l device in the SCH5617 may be reprogrammed through the internal configuration registers. There are up to 48 0 (960 for Standard Mode Parallel Port) I/O address location options, a Serialized IRQ interface, and four DMA channels.
