**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.

Note: Dates vary for when these chips were first available. Two
databooks have been used one from '86 the other from '91. Not all the
chips are listed in the '86 databook, the date of '87 is an
assumption.

***Info:
The UM82C206 Integrated Peripheral controller includes two 8237 DMA
controllers, two 8259 Interrupt controllers, one 8254 Timer/Counter,
one MC146818 compatible Real Time Clock, an additional 64 bytes CMOS
RAM, one 74LS612 memory mapper, and some top level decoder/
configuration logic circuits. It is a single chip integration of all
main peripheral parts attached to the X bus of PC/AT architecture.
While providing full compatibility with PC/AT architecture, the
UM82C206 also offers some enhanced features and improved speed
performance. These include an additional 64 bytes of user definable
CMOS RAM in real time clock and drastically reduced recovery time for
the 8237, 8259 and 8254. Programmable wait state option is provided
for the DME cycles and CPU I/O cycles accessing this chip. This chip
also provides programmable 8 or 4 MHz DMA clock selection. The
UM82C206 is implemented using advanced 1.5u CMOS design technology and
is packaged in an 84-pin PLCC.
