**82495XP/490XP Cache Controller / Cache RAM (for i860)       06/05/91
***Notes:...
***Info:
The Intel 82495XP cache controller and 82490XP cache RAM, when coupled
with a user-implemented memory  bus controller, provide a second-level
cache  subsystem  that eliminates  the  memory  latency and  bandwidth
bottleneck for  a wide  range of multiprocessor  systems based  on the
i860 XP  microprocessor. The CPU  interface is optimized to  serve the
i860  XP microprocessor  with zero  wait  states at  up to  50 MHz.  A
secondary cache  built from the  82495XP and 82490XP isolates  the CPU
from  the memory subsystem;  the memory  can run  slower and  follow a
different protocol than the i860 XP microprocessor.

**VL82C110 Combination I/O chip                                      ?
***Info:
The VL82C110  Combination I/O  chip replaces  several of  the commonly
used peripherals  found in  PC/AT-compatible computers.   The VL82C110
contains a 765A compatible floppy  disk controller with a digital data
clock separator, writ precompensation  logic and the necessary control
registers.  It also contains two 16C450 compatible UARTs, a Centronics
compatible printer port,  and an internal PMU  (power management unit)
which  is  useful  in  applications where  low  power  consumption  is
essential. Additionally,  a PLL clock  circuit is included  to provide
one of seven of the commonly used CPU clock frequencies.  This 100-pin
chip allows designers to implement a very cost-effective, minimum chip
count motherboard  containing functions  that are common  to virtually
all PCs.

The  internal  PMU provides  a  Sleep  output  which OS  asserted  via
automatically after a programmable time  delay period of inactivity in
any of the major on-chip  functions. Conversely, the sleep output will
be  de-asserted when  any activity  is detected  to any  of the  major
on-chip functions.

The on-chip UARTs are 100% software compatible with the VL16C450 ACE.

The bidirectional  parallel port  provides a PS/2  software compatible
interface between a Centronics-style  printer and the VL82C110. Direct
drive is  provided so that all  that is necessary to  interface to the
line  printer  is  a resistor-capacitor  network.   The  bidirectional
feature  (option)  is  software   programmable  for  backwards  PC/AT-
compatibility.

The  on-chip  disk  controller  OS  100% compatible  to  the  industry
standard  765A.  The  internal digital  data separator  is  capable of
operating up to  a 500 kb/s data rate.  The Controller also implements
all of the DP8473 disk controller functions.

The necessary signals  are provided to implement  the Integrated Drive
Electronics (IDE) interface.

A 24 MHz oscillator is included  for UART baud rate generation and the
floppy  disk  controller clock,  It  is  also  used to  generate,  via
software control, a 20, 25, 32, 40,  50, 66 or 80 MHz output which can
be used as a CPU input clock. This feature may be disabled at power-up
reset time.

Software  configurable registers  are provided  to enable  and disable
major blocks, assign addresses, and control other functions within the
VL82C110.
