82371AB General Description
The 82371AB PCI ISA IDE Xcelerator (PIIX4) is a multi-function PCI device implementing a PCI-to-ISA bridge function, a PCI IDE function, a Universal Serial Bus host/hub function, and an Enhanced Power Management function. As a PCI-to-ISA bridge, PIIX4 integrates many common I/O functions found in ISA-based PC systems-two 82C37 DMA Controllers, two 82C59 Interrupt Controllers, an 82C54 Timer/Counter, and a Real Time Clock. In addition to compatible transfers, each DMA channel supports Type F transfers. PIIX4 also contains full support for both PC/PCI and Distributed DMA protocols implementing PCI-based DMA. The Interrupt Controller has Edge or Level sensitive programmable inputs and fully supports the use of an external I/O Advanced Programmable Interrupt Controller (APIC) and Serial Interrupts. Chip select decoding is provided for BIOS, Real Time Clock, Keyboard Controller, second external microcontroller, as well as two Programmable Chip Selects. PIIX4 provides full Plug and Play compatibility. PIIX4 can be configured as a Subtractive Decode bridge or as a Positive Decode bridge. This allows the use of a subtractive decode PCI-to-PCI bridge such as the Intel 380FB PCIset which implements a PCI/ISA docking station environment.
PIIX4 supports two IDE connectors for up to four IDE devices providing an interface for IDE hard disks and CD ROMs. Up to four IDE devices can be supported in Bus Master mode. PIIX4 contains support for "Ultra DMA/33"synchronous DMA compatible devices.
PIIX4 contains a Universal Serial Bus (USB) Host Controller that is Universal Host Controller Interface (UHCI) compatible. The Host Controller's root hub has two programmable USB ports.
PIIX4 supports Enhanced Power Management, including full Clock Control, Device Management for up to 14 devices, and Suspend and Resume logic with Power On Suspend, Suspend to RAM or Suspend to Disk. It fully supports Operating System Directed Power Management via the Advanced Configuration and Power Interface (ACPI) specification. PIIX4 integrates both a System Management Bus (SMBus) Host and Slave interface for serial communication with other devices.
