**HT18          80386SX Single Chip                            c:Sep91
***Info:
The HT18  is an advanced PC/AT compatible,  single-chip 80386SX design
solution. This  highly integrated single chip allows  simple, low cost
system  design options  while  featuring high  performance, low  power
consumption,  and minimum board  space requirements.   Advanced memory
management features  include support  for page mode,  with 2  or 4-way
interleaving  in both pipelined  and non-pipelined  modes(18A/B only).
Extended Hardware EMS  options include dual sets of  32 registers with
multiple context operation. Revisions A/B support 256K and 1M DRAMs in
1 by 1,  1 by 4, and 1  by 9 device configurations. Rev  C supports 4M
devices, as well.  A Shadow RAM  option for System Video BIOS and dual
or single system ROM BIOS support adds to overall design versatility.

A  complete PC/AT  compatible  system with  advanced  features may  be
implemented with minimal external support logic. The HT18 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. An asynchronous AT Bus clock
allows  for a  constant 8MHz  Bus clock  rate for  highest  bus device
compatibility as defined in IEEE Spec P996. This device is packaged in
a 208-pin  Plastic Quad Flat  Pack combining several  external buffers
into this space saving solution.
