**ACC2051/NT PCI Single Chip Solution for Notebook Applications    c96
***Info:
The ACC Micro 2051nt, PCI Single Chip Solution , is a true 64-bit high
performance notebook solution to  support Intel Pentium, Cyrix M1, and
AMD K5 microprocessors.  The rich feature set of  the ACC Micro 2051nt
includes: level  2 write-back  cache controller, DRAM  controller, PCI
interface, ISA interface, and  ACC Micro Power Management control. The
integrated level  2 cache controller supports different  types of SRAM
such as burst, pipeline burst, or standard asynchronous SRAM. Extended
Data  Output  (EDO, and  Fast  Page Mode  DRAM  are  supported by  the
integrated DRAM controller. The built-in  PCI bus interface can run in
synchronous or  asynchronous mode with mobile/PCI  support for docking
designs.

ACC Micro Power  Management allows the system power  consumption to be
controlled  in  various  operation  modes such  as  Power-on  suspend,
Power-down suspend, Standby, and Doze. The whole system is partitioned
into  four different  power planes:  CPU interface  and level  2 cache
interface,   DRAM  interface,   PCI   bus  interface,   and  ISA   bus
interface. Every power plane, except ISA (which is always at 5.0V) can
be independently configured to either  3.3V or 5.0V. No external level
shifter is required.
