DME1737 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant
Super I/O controller with an LPC interface. Hardware Monitoring
capabilities, enhanced Security features, Power Control logic and
Motherboard Glue logic are included.
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.
CMOS 765B core provides 100% compatibility with IBM PC/XTTM and
PC/ATTM architectures and is software and register
compatible with SMSC's proprietary 82077AA core. 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.
