**VL82C420/144/146     SCAMP IV [no datasheet, some info]          c93
***Notes:
from:http://www.cbronline.com/news/vlsi_technology_has_80486sl_notebook_chip_set

The SCAMP IV set comprises three devices - VL82C420 system controller,
VL82C144  peripheral  combination  chip, and  optional  VL82C146  ExCA
controller. A standard SCAMP IV system design can be completed with as
few as three  TTL components. The devices in the  set interconnect via
the  VLSI  proprietary  Multiplexed  Local  Bus  interface;  they  are
implemented in 0.8 micron CMOS  and support mixed voltage operation at
3V and  5V. The VL82C420  is designed to  be tightly coupled  with the
power-managed Intel  CPUs running at  up to 33MHz including  ones with
clock-  doublers.  The  memory  controller  supports  up  to  32Mb.The
peripherals  chip also  includes floppy  disk controller  with digital
data   separator,    a   16C550-compatible    universal   asynchronous
transmitter-receiver with infra-red support. Power management features
include  socket power  control, 3.3V/5V  suspend with  modem and  ring
resume detection and  power saving with Window inactivity.  Up to four
VL82C146s can be  used in each system. Samples  August, volume October
at $32.50 for the VL82C420, $25.00  for the VL82C144 and $8.50 for the
VL82C146 for 1,000-up.
