**82C898 System/Power Management Controller (non-cache)c:Nov94
***Notes:...
***Info:
Overview
The 82C898 provides a highly integrated solution for fully compatible,
high performance PC/AT platforms. The 82C898 supports 486SX/DX/DX2/DX4
and P24T microprocessors in the most cost effective and power
efficient designs available today. For high-end system applications,
this device offers optimum performance for systems running up to
50MHz.
Based fundamentally on OPTi’s proven 82C801 and 82C802 design
architectures, the 82C898 adds additional memory configurations and
extensive power management control for the processor and other
motherboard components.
The 82C898 supports the latest in 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
Integrated Peripherals Controller (IPC), all in a single 208-pin PQFP
(Plastic Quad Flat Pack) for low cost.
Power Management
Figure 2-1 [see datasheet] exemplifies the flexibility of an
82C898/82C602-based designs GREEN strategy. System designs can easily
accommodate both SLe and non-SLe CPUs. If an Intel non-SLe CPU is
used, SMI#, SMIAOT#, and FLUSH# are no connects. One design can easily
accommodate both types of processors with minimal changes for
upgrades.
