**82C895 System/Power Management Controller (cached) c:Sep94
***Notes:...
***Info:
Overview
The 82C895 provides a highly integrated solution for fully compatible,
high performance PC/AT platforms. This chipset will support 486SX/
DX/DX2/DX4 and P24T microprocessors in the most cost effective and
power efficient designs available today. For power users, this
chipset offers optimum performance for systems running up to 50MHz.
Based fundamentally on OPTi's proven 82C801 and 82C802 design
architectures, the 82C895 adds additional memory configurations and
extensive power management control for the processor and other
motherboard components.
The 820895 supports the latest write-back processor designs from
Intel, AMD, and Cyrix, as well as supporting the AT bus and VESA local
bus for compatibility and performance. It also includes an
82C206-compatible Integrated Peripherals Controller (IPC). all in a
single 208-pin PQFP (Plastic Quad Flat Pack) package for low cost.
2.1 Power Management
This block diagram [see datasheet] exemplifies the flexibility of the
82C895/82C602 GREEN strategy. System designs can easily accommodate
both SLe and non-SLe CPUs. If an Intel non-SLe CPU is used, SMI#,
SMIACT#, and FLUSH# are no connects. One design can easily accomm-
odate both types of processors with minimal changes for upgrades.
