1-9 CHIPSET
 VIA Apollo KT266
The KT266 / VT8366 and VT8233 chipset is a high performance,
cost-effective and energy efficient system controller for the implementation
of AGP / PCI desktop personal computer systems based on 64-bit Socket-A
(AMD Athlon) processors.
The KT266 chip set consists of the VT8366 system controller (552 pin BGA)
and the VT8233 V-Link south bridge (376 pin BGA). The VT8366 Host
system controller provides superior performance between the CPU, DRAM,
AGP bus, and V-Link bus with pipelined, burst, and concurrent operation.
The VT8233 V-Link Client controller is a highly integrated PCI / LPC
controller.
Its internal bus structure is based on 33 MHz PCI bus that provides 2x
bandwidth compare to previous generation PCI / ISA bridge chips. The
VT8233 also provides a 266MB/sec bandwidth Host/Client V-Link interface
with V-Link-PCI and V-Link-LPC controllers. It supports five PCI slots of
arbitration and decoding for all integrated functions and LPC bus.
The VT8366 supports eight banks of DDR SDRAM up to 4 GB. The
DRAM controller supports standard Synchronous DRAM (SDRAM), and
Virtual Channel SDRAM (VC SDRAM) SDRAM in a flexible mix / match
manner, or it can be configured to support Double-Data-Rated (DDR)
SDRAM mode. The DDR 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 / 32M / 64M xN 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 either
synchronous or pseudo-synchronous mode with the host CPU bus frequency
(100 / 133 MHz).
The VT8366 Host system controller also supports full AGP v2.0 capability
for maximum bus utilization including 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 / NT5
miniport drivers are supported for interoperability with major AGP-based
3D and DVD-capable multimedia accelerators.
The VT8366 Host system controller supports two 32-bit 3.3 system buses
(one AGP and one V-Link) 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 V-Link
operation. For V-Link Host operation, forty-eight levels (doublewords) of
post write buffers and sixteen levels (doublewords) of prefetch buffers are
included for concurrent V-Link bus and DRAM/cache accesses. When
combined the V-Link Host / Client controllers, it realizes a complete PCI
sub-system and 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 write-back forward to
PCI master, and L1 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.
The 376-pin Ball Grid Array VT8233 Client V-Link PCI / LPC controller
supports four levels (doublewords) of line buffers, type F DMA transfers
and delay transaction to allow efficient PCI bus utilization and (PCI-2.1
compliant). The VT8233 integrated PCI controller and PCI arbitration for
up to five PCI slots. One of the PCI REQ / GNT pair can be configured as
high-priority to better support a low latency PCI bus master device. The

networking.
The VT8233 also includes an integrated keyboard controller with PS2
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-33/66/100 for
33/66/100 MB/sec transfer rate, integrated USB interface with root hubs and
six function ports with built-in physical layer transceivers, Distributed DMA
support, and OnNow / ACPI compliant advanced configuration and power
management interface.
For sophisticated power management, the Apollo KT266 chipset provides
independent clock stop control for the CPU / SDRAM, PCI, and AGP buses
and 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 VT8233 south bridge chip,
a complete power conscious PC main board can be implemented with no
external TTLs.
The Apollo KT266 chipset is ideal for high performance, high quality, high
energy efficient and high integration desktop and notebook AGP / PCI /
LPC computer systems.
The VT8233 South Bridge is a high integration, high performance,
power-efficient, and high compatibility device that supports Intel and
non-Intel based processor to V-Link bus bridge functionality to make a
complete Microsoft PC99-compliant PCI/ISA system. In addition to
complete ISA extension bus functionality, the VT8233 includes standard
intelligent peripheral controllers:
a) IEEE 802.3 compliant 10 / 100 Mbps PCI bus master Ethernet MAC with
standard MII interface to external PHYceiver.
b) Master mode enhanced IDE controller with dual channel DMA engine
and interlaced dual channel commands. Dedicated FIFO coupled with

Motherboard Description SY-K7V DRAGON
14
scatter and gather master mode operation allows high performance
transfers between PCI and IDE devices. In addition to standard PIO and
DMA mode operation, the VT8233 also supports the UltraDMA-33
standard to allow reliable data transfer rates up to 33 MB/sec throughput.
The VT8233 also supports the UltraDMA-66 / 100 standard. The IDE
controller is SFF-8038i v1.0 and Microsoft Windows-family compliant.
c) Universal Serial Bus controller that is USB v1.1 and Universal HCI v1.1
compliant. The VT8233 includes the root hub with six function ports with
integrated physical layer transceivers. The USB controller allows hot plug
and play and isochronous peripherals to be inserted into the system with
universal driver support. The controller also implements legacy keyboard
and mouse support so that legacy software can run transparently in a
non-USB-aware operating system environment.
d) Keyboard controller with PS2 mouse support.
e) Real Time Clock with 256 byte extended CMOS. In addition to the
standard ISA RTC functionality, the integrated RTC also includes the date
alarm, century field, and other enhancements for compatibility with the
ACPI standard.
