The 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. 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 true 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.
