**VT82C496G Pluto, Green PC 80486 PCI/VL/ISA System <05/30/94
***Info:
The VT82C496G is a cost-effective implementation of a high
integration, high performance and high energy efficient VL/ISA system
based on the 80486SX/DX/DX2/DX4 or compatible processor. With an
optional VT82C505 VL-PCI bridge, the system can be extended to the
PCI/VL/ISA platform that offers top rated PCI performance and proven
PCI-2.0 compliance. In either case, the VT82C496G interfaces directly
with the VT82C406MV IXP (Integrated X-bus Peripherals) that replaces
the multiclock generator, the keyboard controller with PS2 mouse
support, the DS-1285 style real time clock with 128 byte of CMOS RAM
and certain amount of glue logic. Less than ten TTLs are required for
a complete main board implementation in addition to the chips
mentioned above.
In addition to the VL bus controller, cache and DRAM controller and
ISA bus controller with the 82C206 peripherals (DMA, interrupt
controller and timer), the VT82C496G also includes a flexible CPU
interface, a notebook class power management unit and a local bus IDE
controller to meet the demand of the state-of-art computing
requirement. The function block diagram of the VT82C496G is indicated
in Figure 1. The system block diagram of a PCI/VL/ISA system based on
the VT82C496G is indicated in Figure 2. [see datasheet]
