SCH3112数据手册集成电路（IC）的专用规格书PDF

描述 Description

TheSCH3112/SCH3114/SCH3116 Product Family is a 3.3V (Super I/O Block is 5Vtolerant) PC99/PC2001 compliant Super I/O controller with an LPC interfacethat also includes Hardware Monitoring capabilities, enhanced Securityfeatures, Power Control logic and Motherboard Glue logic. Thesethree Product Families incorporate complete legacy Super I/O, including afloppy disk controller with Microchip's true CMOS 765B core and enhanceddigital data separator. The true CMOS 765B core provides 100%compatibility with IBM PC/XTTM and PC/ATTM architectures and is softwareand register compatible with Microchip's proprietary 82077AA core. The SCH3112 family supports multiple low power-down modes, and theISA Plug-and-Play Standard register set (Version 1.0a).Family partsSCH3112I-NUSCH3112I-NU-R00SCH3112-NU
