**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.

**TACT82411   Snake  Single-Chip AT Controller                     c90
***Notes:...
***Info:
The new  Texas Instruments single  chip TACT82411 contains  the system
logic and most of the peripheral functions needed to build a 12-20 MHz
80286-based computer that is 100%  compatible with the IBM PC-AT. Only
seven logic components plus  memory, CPU, and coprocessor are required
to  complete an  80286 system  board.  The chip  also supports  system
boards which use the 80386SX.   The TACT82411 is packaged in a 208-pin
quad flat pack (QFP).

Because  the TACT82411 is  manufactured with  TI's 1-micron  EPIC CMOS
technology,  it provides a  high level  of integration  and high-speed
state-of-the-art performance at relatively low power consumption. This
combination  permits  systems  that  are smaller,  lighter,  and  more
sophisticated,  but with  lower power  consumption -  an  ideal comab-
ination  for portable,  battery-powered  systems such  as laptop  com-
puters.  Another benefit  of high-integration is increased reliability
due to fewer board connections.   In addition, product cost is reduced
because new system design and testing are simplified.

Redesign  of existing multi-chip  or discrete  80286 system  boards is
easy and  cost-effective because  of the straightforward  and flexible
structure of  the TACT82411 chip. System boards  which were originally
designed to operate at 12/16 MHz  can be easily upgraded to operate at
20 MHz. Non-PC  applications using the 80286, such  as instrument con-
trol, automobiles,  and medical equipment,  can also benefit  by using
the TACT82411 chip. Architectural variations can be easily implemented
for  special-purpose systems such  as LAN-based  diskless workstations
and PC-based portable test equipment.
