**CS8221   NEW Enhanced AT (NEAT)   (82C211/82C212/82C215/82C206)  c86...
***Info:
The  CS8221  PC/AT  compatible  NEAT  CHIPSet  is  an  enhanced,  high
performance 4  chip VLSI implementation (including the  82C206 IPC) of
the control logic  used on the IBM Personal  Computer AT. The flexible
architecture of  the NEAT CHIPSet  allows it to  be used in  any 80286
based system.

The  CS8221 NEAT  CHIPSet  provides a  complete  286 PC/AT  compatible
system, requiring only 24 logic components plus memory devices.

The CS8221 NEAT CHIPSet consists of the 82C211 CPU/Bus controller, the
82C212  Page/interleave   and  EMS  Memory   controller.   the  82C215
Data/Address buffer  and the 82C206  Integrated Peripherals Controller
(IPC).

The NEAT  CHIPSet supports the local  CPU bus, a 16  bit system memory
bus, and the  AT buses as shown in the NEAT  System Block Diagram [see
datasheet].  The  82C211 provides synchronization  and control signals
for all  buses. The 82C211 also  provides an independent  AT bus clock
and allows for  dynamic selection between the processor  clock and the
user  selectable AT  bus clock.   Command delays  and wait  states are
software configurable,  providing flexibility  for slow or  fast peri-
pheral boards.

The  82C212  Page/interleave and  EMS  Memory  controller provides  an
interleaved  memory sub-system  design with  page mode  operation.  It
supports  up to 8  MB of  on-board DRAM  with combinations  of 64Kbit,
256Kbit  and 1Mbit  DRAMs. The  processor  can operate  at 16MHz  with
0.5-0.7 wait  state memory  accesses, using 100  nsec DRAMs.   This is
possible through  the Page Interleaved memory scheme.   The Shadow RAM
feature  allows taster  execution of  code  stored in  EPROM, by  down
loading code  from EPROM to  RAM. The RAM  then shadows the  EPROM for
further code execution. In a  DOS environment, memory above 1Mb can be
treated as LIM EMS memory.

The  82C215 Data/Address  buffer provides  the buffering  and latching
between the local CPU address  bus and the Peripheral address bus.  It
also provides buffering between the  local CPU data bus and the memory
data bus. The parity bit  generation and error detection logic resides
in the 82C215.

The 82C206  Integrated Peripherals Controller  is an integral  part of
the  NEAT CHIPSet.   It is  described in  the 82C206  Integrated Peri-
pherals Controller data book.

System Overview
The CS8221  NEAT CHIPSet  is designed for  use in  12 to 16  MHz 80286
based  systems  and  provides  complete  support  for  the  IBM  PC/AT
bus.  There are four  buses supported  by the  CS8221 NEAT  CHIPSet as
shown in  Figure 1 [see  datasheet]: CPU local  bus (A and  D), system
memory bus (MA and MD), I/O channel bus (SA and SD), and X bus (XA and
XD). The system  memory bus is used to interface the  CPU to the DRAMs
and EPROMs  controlled by the 82C212.   The I/O channel  bus refers to
the bus supporting the AT bus  adapters which could be either 8 bit or
16 bit  devices. The X bus refers  to the peripheral bus  to which the
82C206 IPC and other peripherals are attached in an IBM PC/AT.
