***Notes:...
***Info:
The VT82C680 Apollo-P6 is a high performance, cost-effective and
energy efficient chip set for the implementation of PCI/ISA desktop
and notebook personal computer systems based on the 64 bit Intel
Pentium-Pro super-scalar processors. The chipset supports multi-
Pentium-Pro configuration with Intel GTL+ driver and receiver inter-
face up to 66 MHz external CPU bus speed. The chipset supports the
Pentium-Pro CPU multi-phase bus protocols for split transactions, four
level deep in-order queue and deferred transactions for optimal CPU
throughput.
The VT82C680 chip set consists of the VT82C685 system controller, the
VT82C687 data buffer and the VT82C586 PCI to ISA bridge. The VT82C680
supports six banks of DRAMs up to 1 GB. The DRAM controller supports
Standard Page Mode DRAM, EDO-DRAM, Burst EDO-DRAM and Synchronous DRAM
in a flexible mixed/match manner. The Burst-EDO and Synchronous DRAM
allows zero wait state bursting between the DRAM and the VT82C687 data
buffers at 66 MHz. The six banks of DRAM allow arbitrary mixture of
1M/2M/4M/8M/16MxN DRAMs with optional bank-by-bank ECC and parity
support. The chipset supports sixteen level (quadwords) of CPU to DRAM
write buffers and sixteen level (quadwords) of DRAM to CPU read
buffers to maximize the CPU bus and DRAM utilization. The peak data
transfer rate for the EDO and Synchronous DRAM (or Burst EDO) DRAMs is
266 MB/s and 532 MB/s, respectively.
The VT82C680 supports 3.3/5v 32 bit PCI bus with 64 bit to 32 bit data
conversion. Sixteen levels (doublewords) of post write buffers are
included to allow for concurrent CPU and PCI operation. Consecutive
CPU addresses are converted into burst PCI cycles with Byte merging
capability for optimal CPU to PCI throughput. For PCI master
operation, sixteen levels (doublewords) of post write buffers and
thirty-two levels (doublewords) of prefetch buffers are included for
concurrent PCI bus and DRAM/cache accesses. The chipset 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, the chipset supports advanced features
such as snoop ahead, snoop filtering, CPU write-back forward to PCI
master and CPU write-back merged with PCI post write buffers to
minimize PCI master read latency and DRAM utilization. The VT82C586
PCI to ISA bridge supports four levels (doublewords) of line buffers,
type F DMA transfers and delay transaction to allow efficient PCI bus
utilization (PCI-2.1 compliant). The VT82C586 also includes integrated
keyboard controller with PS2 mouse support, integrated DS12885 style
real time clock with extended 128 Byte CMOS RAM, integrated master
mode enhanced IDE controller with full scatter and gather capability
and extension to 33 MB/sec UltraDMA-33 transfer rate, integrated USB
interface with root hub and two function ports with built-in physical
layer transceiver, and OnNow/ACPI compliant advanced configuration and
power management interface. A complete main board can be implemented
with only six TTLs.
The VT82C680 is ideal for high performance, high quality, high energy
efficient and high integration desktop and notebook PCI/ISA computer
systems.
