Ø VT8363

The KT133 chip set consists of the VT8363 system controller (552 pin
BGA) and the VT82C686A 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 VT8363 support six banks of DRAMs up to 1.5GB. The DRAM
controller supports standard 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 six banks of
DRAM can be composed of an arbitrary mixture of 1M / 2M / 4M / 8M /
16M / 32MxN DRAMs.
The VT8363 system controller also supports full AGP v2.0 capability for
maximum bus utilization including 1x, 2x and 4x mode transfers, SBA
(SideBand 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 quadwords 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 operating environments. Both Windows-95 VXD and
Windows-98 / Windows 2000 miniport drivers are supported for
interoperability with major AGP-based 3D and DVD-capable multimedia
accelerators.
The VT8363 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 (doublewords) of post
write buffers are included to allow for concurrent CPU and PCI operation.
For PCI master operation, forty-eight levels (doublewords) of post write

12

Motherboard Description SY-K7VTA

buffers and sixteen levels (doublewords) 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-Read-Multiple and Memory-Write-Invalid commands to
minimize snoop overhead. In addition, advanced features are supported
such as snoop ahead, snoop filtering, L1/L2 write-back forward to PCI
master, and L1/L2 write-back 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 overall system performance.

Ø VT82C686A

The VT82C686A PSIPC (PCI Super-I/O integrated Peripheral Controller)
is a high integration, high performance, power-efficient, and high

Motherboard Description SY-K7VTA

1-9.4 PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel of the
motherboard. The +5 V lines to keyboard and mouse connectors are
protected with a fuse that prevents motherboard components from being
damaged when an over-current condition occurs.

Note

The mouse and keyboard can be plugged into either PS/2 connector.
Power to the computer should be turned off before a keyboard or mouse is
connected or disconnected.

The keyboard controller contains code, which provides the traditional
keyboard and mouse control functions, and also supports Power On/Reset
password protection. Power On/Reset password can be specified in the
BIOS Setup program.

The keyboard controller also supports the hot-key sequence
<Ctrl><Alt><Del>, software reset. This key sequence resets the
computer’s software by jumping to the beginning of the BIOS code and
running the Power On Self Test (POST).

1-9.5 Infrared Support

On the front panel I/O connector, there are six pins that support Hewlett
Packard HSDL-1000 compatible infrared (IR) transmitters and receivers.
In the Setup program, Serial Port B can be direct4d to a connected IR
device. (In this case, the Serial Port B connector on the back panel cannot
be used.) The IR connection can be used to transfer files to or from
portable devices like laptops, PDAs, and printers. The Infrared Data
Association (IrDA) specification supports data transfers of 115Kbits/sec at
a distance of 1 meter.

1-10 HARDWARE MONITOR

The optional hardware monitor subsystem provides low-cost
instrumentation capabilities. The features of the hardware monitor

17

Motherboard Description SY-K7VTA

subsystem include:

Ø An integrated ambient temperature sensor
Ø Fan speed sensors, which monitor the fan 1 and fan 2 connector.
Ø Power supply voltage monitoring to detect levels above or below

acceptable values
When suggested ratings for temperature, fan speed, or voltage are
exceeded, an interrupt is activated. The hardware monitor component
connects to the SMBus.

1-11 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.

3. Seat the processor in the socket completely and without forcing.

4. Then close the socket handle to secure the CPU in place.

Remember to connect the CPU Cooling Fan to the
appropriate power connector on the Motherboard. The fan is

a key component that will ensure system stability. The fan
prevents overheating, therefore prolonging the life of your
CPU.

FOC ( Fan-Off Control )

The newly designed SOYO “FOC” is based on the concept of total
protection for CPU, which is very different from currently seen on the
market. The H/W control function is used to see a passive security system
of monitoring and warning. “FOC”, designed by SOYO, gives emphasis
on the concept of total protection. S/W Simultaneous Signal Follow-ups
techniques and Auto Power Off System are included to prevent all
possible damage caused by the MAL-functioning of the CPU fan. With the
help of “O/S On Time Monitoring And Warning” function, provided by
the H/W monitoring system, the double-protection purpose is achieved.

“FOC” includes the following functions:
(1) Simultaneous Signal Follow Ups: Before the system enters the O/S,

H/W will detect the signals of the CPU fan pins, get their
revolution information and send it to the BIOS.

(2) Auto Power Off System: If the BIOS gets the information of CPU

fan revolution, it goes on working normally. If not, it will
inform the system and have the power supply disconnected
immediately. Thus, the CPU is protected from over heating.

Note: The following must be observed to secure the normal functioning of
“Fan-Off Control”:

1. CPU fan with sensor pins must be used.

2. CPU fans approved by AMD are strongly recommended.

3. The “HOT KEY” function is provided for the CPU fans without

sensor pins, to avoid the power off. Users may press the “Insert”
key to jump over the “Power Off” mode; go to the BIOS and
disable “FOC”. Now system can be booted normally.

4. The power connector of the CPU fan must be connected to the

specified “CPU Fan Connector” on the motherboard to secure the
normal functioning of the system.

We provide the following User-Friendly protection features:

1.Fan-Off Control : The motherboard detects the status of the CPU

fan and protects the CPU by automatically disconnecting the
power supply. The default value of this function is Enable. After
booting up, the user may disable it.

2.CPU Socket Sticker : Users will find a sticker on the CPU socket,

which reminds them of the correct usage of the K7 CPU.

3. Heat Dissipation Paste: Heat Dissipation Paste is included for all

Socket-A motherboards, to enhance the heat dissipation

capability.
Furthermore, we strongly recommend our users to enable the function of
H/W monitoring in the BIOS. This function, together with the FOC,
provide the total protection to the CPU and allow it to maximize its
performance.
