***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.
