**82420EX     PCIset (for 486) EX (Aries)   (82425EX/82426EX)   <Dec94
***Notes:...
***Info:
The  82420EX   PCIset  is  the  foundation  for   the  Value  Flexible
Motherboard  solution  for  entry-level Intel486  processor-based  PCI
systems. The  Value Flexible Motherboard  solution, including 82420EX,
Intel486  processor, 82091AA  Advanced  Integrated Peripherals,  82C42
Keyboard Controller, Flash BIOS, and  Plug & Play software, drives PCI
into  the  mainstream.  The  82420EX  PCIset  is  a highly  integrated
solution enabling low cost, small form factor motherboard designs. All
Intel486   processors  and  upgrades   are  supported,   including  L1
write-back  and Intel  SMM  power  management. PCI  Local  Bus IDE  is
incorporated for higher performance IDE at no additional cost.

The 82420EX  was designed from the  ground up for  PCI performance. It
consists of two  components - the 82425EX PCI  System Controller (PSC)
and  the 82426EX ISA  Bridge (IB).   The PSC  integrates the  L2 cache
controller and the DRAM controller. The cache controller supports both
write-through and  write-back cache policies  and cache sizes  from 64
KBytes   to  512   KBytes   in  an   interleaved  or   non-interleaved
configuration. The DRAM controller  interfaces main memory to the Host
Bus  and the PCI  Bus.  The  PSC supports  a two-way  interleaved DRAM
organization for optimum performance.  Up to ten single-sided SIMMs or
four double-sided and two single-sided  SIMMs provide a maximum of 128
MBytes of  main memory. The PSC  provides memory write  posting to PCI
for enhanced CPU-to-PCI memory write performance. In addition, the PSC
provides a high performance PCI Local Bus IDE interface.

The IB is the bridge between  the ISA Bus and Host Bus, and integrates
the common  I/O functions  found in today’s  ISA-based PC systems  - a
seven channel DMA controller, two 82C59 interrupt controllers, an 8254
timer/counter, Intel  SMM power management support,  and control logic
for NMI generation. The IB also provides the decode for external BIOS,
real time  clock, and  keyboard controller. Edge/Level  interrupts and
interrupt steering are supported  for PCI plug and play compatibility.
The  IB integrates the  ISA address  and data  path, reducing  TTL and
system cost.  In addition, the integration of  system clock generation
logic eliminates the need for external host and PCI clock drivers.
