PRODUCT PREVIEW
General Description
The DME1737 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller
with an LPC interface. DME1737 also includes Hardware Monitoring capabilities, enhanced Security
features, Power Control logic and Motherboard Glue logic.
The DME1737's hardware monitoring capability includes temperature, voltage and fan speed
monitoring. It has the ability to alert the system to out-of-limit conditions and automatically control the
speeds of multiple fans. There are four analog inputs for monitoring external voltages of +5V, +5VTR,
+12V and Vccp (core processor voltage), as well as internal monitoring of the SIO's VCC, VTR, and
Vbat power supplies. The DME1737 includes support for monitoring two external temperatures via
thermal diode inputs and an internal sensor for measuring ambient temperature. The nHWM_INT pin
is implemented to indicate out-of-limit temperature, voltage, and FANTACH conditions. The hardware
monitoring block of the DME1737 is accessible via the System Management Bus (SMBus). The same
interrupt event reported on the nHWM_INT pin also creates PME wakeup events and speaker alarm
annunciation.
The Motherboard Glue logic includes various power management and system logic including
generation of nRSMRST, SMBus buffers, and buffered PCI reset outputs.
The DME1737 incorporates complete legacy Super I/O functionality including an 8042 based keyboard
and mouse controller, an IEEE 1284, EPP, and ECP compatible parallel port, one serial port that is
16C550A UART compatible, one IrDA 1.0 infrared ports, and a floppy disk controller with SMSC's true
CMOS 765B core and enhanced digital data separator, The true CMOS 765B core provides 100%
compatibility with IBM PC/XT and PC/AT architectfures and is software and register compatible with
SMSC's proprietary 82077AA core. System related functionality, which offers flexibility to the system
designer, General Purpose I/O control functions, control of two LED's, and fan control using fan
tachometer inputs and pulse width modulator (PWM) outputs
The DME1737 is ACPI 1.0/2.0 compatible and therefore supports multiple low power-down modes. It
incorporates sophisticated power control circuitry (PCC), which includes support for keyboard and
mouse wake-up events.
The DME1737 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 DME1737 may be reprogrammed
through the internal configuration registers. There are up to 480 (960 - Parallel Port) I/O address
location options, a Serialized IRQ interface, and Three DMA channels.
