**82C802G/GP System/Power Management Controller (cached) c:93
***Notes:...
***Info:
The 82C802G/GP 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 82C802G/GP adds additional memory configurations
and extensive power management control for the processor and other
motherboard components.
The 82C802G/GP 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 Plat Pack) package for low cost.
Power Management Block
Figure 2-1 [see datasheet] exemplifies the flexibility of the
82C802G/GP/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
accommodate both types of processors with minimal changes for
upgrades.
