**82C206   Integrated Peripheral Controller                        c86
***Info:
The 82C206 Integrated Peripheral  Controller incorporates two 8237 DMA
controllers.   two  8259   Interrupt  controllers.   one  8254  Timer/
Counter.   one MC146818  Real Time  Clock, 74LS612  memory  mapper. in
addition to  several other  TTL/SSI interface logic  chips to  offer a
single  chip  integration  of  all  the peripherals  attached  to  the
peripheral  bus (X-Bus) in  the IBM  PC AT  While offering  a complete
compatibility to the IBM PC  AT architecture. the chip offers enhanced
features and  improved speed performance. These  include an additional
64 bytes of user RAM for  the Real Time Clock, and drastically reduced
recovery  specifications for the  8237, 8259  and 8254.  Variable wait
state option is  provided for the DMA cycles.  Programmable delays are
provided for the CPU access to the internal registers of the chip. The
chip also provides an option to select 8 or 4 MHz system clock.

The 82C206 along with the  (CS8220 PC AT Compatible CHIPSet provides a
highly  integrated high performance  solution for  a PC  AT compatible
implementation.

The  82C206  is  implemented  usmg  advanced CMOS  technology  and  is
packaged in an 84-pin PLCC.
