**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.
