**F87000   Multi-Mode Peripheral Chip                         11/23/93
***Info:...
***Versions:...
***Features:
o   Fully static design substantially reduces power consumption when 
    compared to discrete TTL designs, allowing direct battery drive.
o   3.3V or 5V operation provides flexibility for system design and 
    allows dynamic 3.3/5V switching of system voltage to further 
    reduce power consumption.
o   Each F8700 device can be strapped to configure one of three 
    buffer modes or a multi-function mode, reducing parts inventory 
    requirements.
o   High integration means each F8700 mode replaces at least seven 
    discrete TTL devices.
o   Full isolation of PCMCIA memory and I/O cards is supported to 
    allow safe insertion and removal of cards, both "hot" and "cold."
o   PCMCIA buffer modes are completely PCMCIA 2.0-compatible.
o   For single PCMCIA card support, Mode 1 buffers 20 address lines 
    and 5 control lines.  Because of the quiet bus design of PC/CHIPm 
    the upper address lines can be connected directly to the PCMCIA 
    card slot in a single card system for full 64MB support.
o   For dual PCMCIA card support, Modes 2 and 3 together buffer all 
    necessary address and control lines for independent 64MB support 
    of each card.
o   Between PCMCIA cycles, the F87000 sets PCMCIA buses and control 
    lines to a low-power state to consume only a fraction of the power 
    used in a standard TTL buffer design.
o   Multi-function mode (Mode 4) provides keyboard scanning, a 
    parallel interface, and IDE interface, a configuration latch, and 
    a 1.8MHz UART clock generation circuit.
o   Keyboard scan interface in the multi-function mode requires only a 
    single external resister pack and provides an interrupt to the 
    system on key depression. The interface can be used instead as 
    general-purpose 16-bit output and 8-bit input ports.
o   Parallel interface in the multi-functional mode allows high-speed,
    PS/2-compatible bidirectional communication with other systems.
o   Configuration latch can be used to control seven external devices 
    plus the UART clock divider. An additional decode line accommo-
    dates an external latch for eight more device control lines.

**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.
