**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.

**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.
