Overview

The AMD-766 peripheral bus controllerTM is an integrated circuit (IC), developed by AMD, to be the system Southbridge component of personal computer chipsets. The AMD-766 peripheral bus controller (the IC) connects to a host memory controller through the PCI bus.

Features

? PCI interface (PCI specification revision 2.2 compliant).

? LPC bus to connect peripherals such as super IO and BIOS.

? Partial ISA bus.

? 8 bits wide.

? Support for Flash BIOS.

? Enhanced IDE controller.

? Support for two dual-drive ports.

? PIO modes 0-4.

? Multi-word DMA.

? UDMA modes up to ATA-100.

? OHCI-based USB host controller with support for four ports.

? Serial IRQ protocol.

? ACPI-compliant power management logic.

? Programmable C2, C3, power-on-suspend, suspend to RAM, suspend to disk, and soft off states.

? Throttling.

? Hardware traps.

? System inactivity timer.

? 32 general-purpose IO (GPIO) pins (some are multiplexed with other hard-wired functions).

? Privacy/security logic (ROM access control).

? Legacy logic.

? Programmable interrupt controller.

? Programmable interval timer.

? DMA controller (for LPC bus).

? Legacy ports.

? IOAPIC controller.

? Real-time clock.

? 256 bytes of CMOS RAM.

? Battery-powered.

? ACPI-compliant extensions.

? SMBus controller with one SMBus port.

? 272-pin BGA package.

? 3.3-volt core and output drivers; 5-volt tolerant input buffers.
