1-9 CHIPSET
Ø VT82C694X
The VIA 694X is a high performance, cost-effective and energy efficient
chip set for the implementation of AGP/PCI/ISA desktop personal
computer systems from 66MHz, 100MHz and 133MHz based on 64-bit
Socket 370 super-scalar processors.
The Via 694X chip set consists of the VT82C694A system controller (510
pin BGA) and the VT82C686B PCI to ISA bridge (352 pin BGA). The
system controller provides superior performance between the CPU,
DRAM, AGP bus, and PCI bus with pipelined, burst, and concurrent
operation.
The VT82C694X supports eight banks of DRAMs up to 1.5GB. The
DRAM controller supports standard Fast Page Mode (FPM) DRAM,
EDO-DRAM, Synchronous DRAM (SDRAM) and Virtual Channel
SDRAM (VC SDRAM), in a flexible mix / match manner. The
Synchronous DRAM interface allows zero wait state bursting between the
DRAM and the data buffers at 66/100/133 MHz. The eight banks of
DRAM can be composed of an arbitrary mixture of
1M/2M/4M/8M/16M/32MxN DRAMs. The DRAM controller also
supports optional ECC (single-bit error correction and multi-bit detection)
or EC (error checking) capability separately selectable on a bank-by-bank
basis. The DRAM controller can run at either the host CPU bus frequency
(66/100/133 MHz) or at the AGP bus frequency (66 MHz) with built-in
PLL timing control.
The VT82C694X system controller also supports full AGP v2.0 capability
for maximum bus utilization including 4x mode transfers, SBA (Side Band
Addressing), Flush/Fence commands, and pipelined grants. An eight level
request queue plus a four level post-write request queue with thirty-two
and sixteen quad words of read and write data FIFO’s respectively are
included for deep pipelined and split AGP transactions. A single-level
GART TLB with 16 full associative entries and flexible CPU/AGP/PCI
remapping control is also provided for operation under protected mode
12
Motherboard Description SY-7VCA2
operating environments. Both Window 95 VxD and Windows 98 /NT5.0
mini port drivers are supported for interoperability with major AGP-based
3D and DVD- capable multimedia accelerators.
The VT82C694X supports two 32-bit 3.3/5V system buses (one AGP and
one PCI) that are synchronous/ pseudo-synchronous to the CPU bus. The
chip also contains a built-in bus-to-bus bridge to allow simultaneous
concurrent operations on each bus. Five levels (double words) of post
write buffers are included to allow for concurrent CPU and PCI operation.
For PCI master operation, forty-eight levels (double words) of post write
buffers and sixteen levels (double words) of prefetch buffers are included
for concurrent PCI bus and DRAM/cache accesses. The chip also supports
enhanced PCI bus commands such as Memory-Read-Line, Memory-ReadMultiple and Memory-Write-Invalid commands to minimize snoop
overhead. In addition, advanced features are supported such as snoop
ahead, snoop filtering, L1 write-back forward to PCI master, and L1 writeback merged with PCI post write buffers to minimize PCI master read
latency and DRAM utilization. Delay transaction and read caching
mechanisms are also implemented for further improvement of over all
system performance.
The 352-pin Ball Grid Array VT82C686B PCI to ISA bridge supports four
levels (double words) of line buffers, type F DMA transfers and delay
transaction to allow efficient PCI bus utilization The VT82C686B also
includes an integrated keyboard controller with PS/2 mouse support,
integrated DS12885 style real time clock with extended 256 byte CMOS
RAM, integrated master mode enhanced IDE controller with full scatter/
gather capability and extension to UltraDMA-33/66 for 33/66 MB/sec
transfer rate, integrated USB interface with root Hub and two function
ports with built-in physical layer transceivers, Distributed DMA supports,
and On Now/ ACPI compliant advanced configuration and power
management interface.
For sophisticated power management, the Via 694X provides independent
clock stop control for the CPU/SDRAM, PCI, and AGP buses and
13
Motherboard Description SY-7VCA2
Dynamic CKE control for powering down of the SDRAM. A separate
suspend-well plane is implemented for the SDRAM control signals for
Suspend-to-DRAM operation. Coupled with the VT82C686B south bridge
chip, a complete power conscious PC motherboard can be implemented
with no external TTLs.
The Via 694X chipset is ideal for high performance, high quality, high
energy efficient and high integration desktop and notebook AGP / PCI /
ISA computer systems.
Ø VT82C686B

1-12 WAKE ON LAN TECHNOLOGY
Wake on LAN technology enables remote wakeup of the computer
through a network. Wake on LAN technology requires a PCI add-in
network interface card (NIC) with remote wakeup capabilities. The remote
wakeup connector on the NIC must be connected to the onboard Wake on
LAN connector. The NIC monitors network traffic at the Ethernet
interface; upon detecting a Magic Packet, the NIC asserts a wakeup signal
that powers up the computer. This feature uses the Wake on LAN
connector.
*
CAUTION
For Wake on LAN, the 5-V standby line for the power supply must be
capable of delivering +5V ±5 % at 720 mA. Failure to provide adequate
standby current when implementing Wake on LAN can damage the power
supply.
