• Manufacturer Part Number: vt82c586a
• Description: Integrated Peripheral Controller
• Manufacturer: ETC-unknow

The VT82C586A PIPC (PCI Integrated Peripheral Controller) is a high integration, high performance and high compatibility
device that supports Intel and non-Intel based processor to PCI bus bridge to make a complete Microsoft PC97 compliant PCI/ISA
system. In addition to complete ISA extension bus functionality, the VT82C586A includes standard intelligent peripheral
controllers:
The VT82C586A 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 VT82C586A 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 four levels (doublewords) of line buffers from
the PCI bus to the ISA bus to further enhance overall system performance.
Preliminary Revision 0.1 October 13, 1996
a) Master mode enhanced IDE controller with dual channel DMA engine and interlaced dual channel commands. Dedicated
b) Universal Serial Bus controller that is USB v1.0 and Universal HCI v1.1 compliant. The VT82C586A includes the root hub
c) Keyboard controller with PS2 mouse support.
d) Real Time Clock with 128 byte extended CMOS. In addition to the standard ISA RTC functionality, the integrated RTC also
e) Notebook-class power management functionality including event monitoring, CPU clock throttling (Intel processor protocol),
f) Plug and Play controller that allows complete steerability of all PCI interrupts to any interrupt channel. Two additional
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 VT82C586A also supports the emerging 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.
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.
includes the date alarm and other enhancements for compatibility with the emerging ACPI standard.

The power management function supports legacy APM v1.2.
interrupt and DMA channels are provided to allow plug and play and reconfigurability of on-board peripherals for Windows
