DME1737数据手册集成电路（IC）的专用规格书PDF

描述 Description

TheDME1737 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliantSuper I/O controller with an LPC interface. Hardware Monitoringcapabilities, enhanced Security features, Power Control logic andMotherboard Glue logic are included.There arefour analog inputs for monitoring external voltages of +5V, +5VTR, +12Vand Vccp (core processor voltage), as well as internal monitoring of theSIO's VCC, VTR, and Vbat power supplies. The trueCMOS 765B core provides 100% compatibility with IBM PC/XTTM andPC/ATTM architectures and is software and registercompatible with SMSC's proprietary 82077AA core. DME1737 is ACPI 1.0/2.0compatible and therefore supports multiple low power-down modes.It incorporates sophisticated power control circuitry (PCC), whichincludes support for keyboard and mouse wake-up events.
