AMD-766 Power Management Controller

Windows device driver information for AMD-766 Power Management Controller

The AMD-766 Power Management Controller device is a peripheral bus controller. It is an IC or integrated chip manufactured by AMD to serve as the system Southbridge component of PC chipsets. This device is capable of connecting to a controller for a host memory via the PCI bus. It has a PCI 2.2 interface and an LPC bus that can be utilized for connecting peripherals like BIOS and super IO. This device is 8 bits wide. This controller device also employs a partial ISA bus, Flash BIOS support, 0 to 4 PIO modes, an improved IDE controller, multi word DMA and support for 2 ports in the dual drive category. The AMD-766 Power Management Controller also has up to ATA – 100 UDMA modes, protocols for serial IRQ, and a USB host controller that is based on OHCI and has support for 4 ports. It is capable of implementing power management logic that is fully compliant with the ACPI.

The AMD-766 Power Management Controller device also has programmable states which include the soft off, suspend to disk, suspend to RAM (random access memory), power on suspend, C3, and C2. It can also employ a timer for system inactivity, hardware traps and throttling. This controller device makes use of 32 general purpose GPIO (IO) pins. Some of these pins are effectively multiplexed for functions that are considered hard wired. It also employs legacy logic, security/ privacy logic (read only memory access control), and an interrupt controller and interval timer that are programmable. The AMD-766 Power Management Controller device also has legacy ports, a real time clock, a DMA controller used for the LPC bus, extensions that are ACPI compliant, and an IOAPIC controller. This device makes use of a CMOS RAM in 256 bytes. It is highly recommended you run a free registry scan for and AMD-766 Power Management Controller errors before installing any driver updates.
