SCH3114-NU General Description

TheSCH3114 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliantSuper I/O controller with an LPC interface that also includes HardwareMonitoring capabilities, enhanced Security features, Power Control logicand Motherboard Glue logic.

Thesystem’s hardware monitoring capability includes temperature, voltage andfan speed monitoring. The Motherboard Glue logic includes various powermanagement and system logic including generation of nRSMRST, aprogrammable Clock output, and reset generation, which include a watchdogtimer. SCH3114 incorporates complete legacy Super I/O, including a floppydisk controller with Microchip's true CMOS 765B core and enhanced digitaldata separator. True CMOS 765B core provides 100% compatibility with IBMPC/XTTM and PC/ATTM architectures and is software and register compatiblewith Microchip's proprietary 82077AA core. The family supports multiplelow power-down modes, and the ISA Plug-and-Play Standard registerset (Version 1.0a).
