Note:  Dates vary  for when  these  chips were  first available.   Two
databooks have been used one from  '86 the other from '91. Not all the
chips  are  listed  in  the  '86  databook, the  date  of  '87  is  an
assumption.

**VT82C598MVP  Apollo MVP3,Single-Chip 66/75/83/100MHz & AGP <09/22/97
***Notes:...
***Info:
The  Apollo MVP3  is  a high  performance,  cost-effective and  energy
efficient chip set  for the implementation of AGP /  PCI / ISA desktop
and notebook personal computer systems from 66 MHz to 100 MHz based on
64-bit Socket-7 (Intel Pentium and Pentium  MMX; AMD K6; Cyrix / IBM 6
x86 / 6x86MX, and IDT / Centaur C6/WinChip) super-scalar processors.

The Apollo-MVP3 chip set consists of the VT82C598MVP system controller
(476 pin BGA) and the VT82C586B PCI to ISA bridge (208 pin PQFP).  The
system  controller  provides  superior  performance between  the  CPU,
optional synchronous cache, DRAM, AGP bus, and PCI bus with pipelined,
burst,  and  concurrent operation.   For  pipelined burst  synchronous
SRAMs, 3-1-1-1-1-1-1-1 timing can be  achieved for both read and write
transactions at 100 MHz.  Tag timing is specially optimized internally
( less  than 4 nsec  setup time) to  allow implementation of  L2 cache
using an external  tag for the most flexible  cache organization (0K /
256K / 512K / 1M /  2M).  Four cache lines (16 quadwords) of CPU/cache
to  DRAM  write  buffers  with concurrent  write-back  capability  are
included on chip to speed up cache read and write miss cycles.

The VT82C598MVP  supports six  banks of DRAMs  up to 768MB.   The DRAM
controller supports standard Fast  Page Mode (FPM) DRAM, EDO-DRAM, and
Synchronous  DRAM (SDRAM)  in  a  flexible mix  /  match manner.   The
Synchronous DRAM interface allows zero wait state bursting between the
DRAM and the  data buffers at 100  MHz.  The six banks of  DRAM can be
composed of an arbitrary  mixture of 1M / 2M / 4M  / 8M / 16MxN 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 / 75 / 83 / 100 MHz)
or at the  AGP bus frequency (66 MHz) with  built-in deskew DLL timing
control.  The VT82C598MVP allows  implementation of the most flexible,
reliable, and high-performance DRAM interface.

The VT82C598MVP  also supports AGP v2.0 compatibility  for maximum bus
utilization  including 2x 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 VT82C598MVP 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 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 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 VT82C586B PCI to ISA  bridge 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 VT82C586B
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 and  gather capability  and extension  to  UltraDMA-33 /
ATA-33 for 33MB/sec transfer  rate, integrated USB interface with root
hub and two function  ports with built-in physical layer transceivers,
Distributed  DMA   support,  and  OnNow  /   ACPI  compliant  advanced
configuration  and  power management  interface.   Using the  low-cost
208-pin  PQFP-packaged VT82C586B  south bridge  chip, a  complete main
board can be implemented with only four TTLs.

For sophisticated  notebook implementations, the  VT82C598MVP 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 324-pin  Ball Grid Array
VT82C596 "Mobile South" chip, a complete notebook PC main board can be
implemented with no external TTLs.

The Apollo MVP3  chipset is ideal for high  performance, high quality,
high energy efficient and high  integration desktop and notebook AGP /
PCI / ISA computer systems.
