**VT82C596/A Mobile PCI Integrated Peripheral Controller <11/05/97
***Info:
The VT82C596 MPIPC (Mobile PCI Integrated Peripheral Controller) is a
high integration, high performance, power-efficient, and high
compatibility device that supports Intel and non-Intel based processor
to PCI bus bridge functionality to make a complete Microsoft
PC97-compliant PCI/ISA system. In addition to complete ISA extension
bus functionality, the VT82C596 includes standard intelligent
peripheral controllers:
a) Master mode enhanced IDE controller with dual channel DMA engine
and interlaced dual channel commands. Dedicated FIFO coupled with
scatter and gather master mode operation allows high performance
transfers between PCI and IDE devices. In addition to standard PIO and
DMA mode operation, the VT82C596 also supports the UltraDMA-33
standard to allow reliable data transfer rates up to 33MB/sec
throughput. The IDE controller is SFF-8038i v1.0 and Microsoft
Windows- 95 compliant.
b) Universal Serial Bus controller that is USB v1.0 and Universal HCI
v1.1 compliant. The VT82C596 includes the root hub with two function
ports with integrated physical layer transceivers. The USB controller
allows hot plug and play and isochronous peripherals to be inserted
into the system with universal driver support. The controller also
implements legacy keyboard and mouse support so that legacy software
can run transparently in a non-USB-aware operating system environment.
c) Keyboard controller with PS2 mouse support.
d) Real Time Clock with 256 byte extended CMOS. In addition to the
standard ISA RTC functionality, the integrated RTC also includes the
date alarm, century field, and other enhancements for compatibility
with the ACPI standard.
e) Notebook-class power management functionality compliant with ACPI
and legacy APM requirements. Multiple sleep states (power-on suspend,
suspend-to-DRAM, and suspend-to-Disk) are supported with hardware
automatic wake-up. Additional functionality includes event
monitoring, CPU clock throttling and stop (Intel processor protocol),
PCI bus clock stop control, modular power, clock and leakage control,
hardware-based and software-based event handling, general purpose I/O,
chip select and external SMI.
f) Full System Management Bus (SMBus) interface.
g) Distributed DMA capability for support of ISA legacy DMA over the
PCI bus. PC/PCI and Serial IRQ mechanisms are also supported for
docking and non-docking applications.
h) Plug and Play controller that allows complete steerability of all
PCI interrupts to any interrupt channel. Three additional steerable
interrupt channels are provided to allow plug and play and
reconfigurability of on-board peripherals for Windows 95 compliance.
i) External IOAPIC interface for Intel-compliant symmetrical multi-
processor systems.
The VT82C596 also enhances the functionality of the standard ISA
peripherals. The integrated interrupt controller supports both edge
and level triggered interrupts channel by channel. The integrated DMA
controller supports type F DMA in addition to standard ISA DMA
modes. Compliant with the PCI-2.1 specification, the VT82C596 supports
delayed transactions so that slower ISA peripherals do not block the
traffic of the PCI bus. Special circuitry is built in to allow
concurrent operation without causing dead lock even in a PCI-to-PCI
bridge environment. The chip also includes eight levels (doublewords)
of line buffers from the PCI bus to the ISA bus to further enhance
overall system performance.
