**HT22          386SX/286 Single Chip (25 MHz)                 c:Sep91
***Info:
The HT22  is an  advanced PC/AT compatible,  single-chip 80386SX/80286
system  design solution.   This highly  integrated single  chip allows
simple, low  cost system design  options while featuring  high perfor-
mance,  low  power  consumption,  and  minimum  board  space  require-
ments. Advanced  memory management  features include support  for page
mode,  2 or  4-way interleaving  in both  pipelined  and non-pipelined
modes.  The EMS  4.0 hardware implementation features dual  sets of 32
registers   with  full   context  support   for   highest  performance
optimization  of  extended local  memory  accesses.   An advanced  EMS
hardware  write-protect option  has  been added  for  maximum EMS  4.0
compatibility. The HTZ2 supports 256K, 1M  and 4MB DRAMs in 1 by 1 and
1 by 4 device configurations for up to 20MB of on-board system memory.
16MB  is  addressed  directly   by  system  resources,  the  remainder
addressed by the EMS mode.

A flexible Shadow  RAM option for System and Video BIOS  as well as 8-
16-bit BIOS options adds to overall design versatility.

A  complete PC/AT  compatible  system with  advanced  features may  be
implemented with minimal external support logic. The HT22 performs all
CPU  and peripheral support  functions in  a single  chip.  Integrated
device  functions include  DMA Controllers,  a Memory  Mapper, Timers,
Counters, Interrupt  Controllers, a Bus Controller  and all supporting
circuitry for PC  core logic requirements. The chip  also contains all
the  necessary  address buffers,  data  transceivers, memory  drivers,
parity  checking   and  supporting  circuitry  for   a  complete  high
performance computer  solution.  An  asynchronous AT Bus  clock allows
for  a constant 8MHz  Bus clock  rate for  highest bus  device compat-
ibility as  defined in IEEE  Spec P996. This  device is packaged  in a
208-pin Plastic Quad Flat Pack.
