SLC90E66

The Victory66 SLC90E66 Enhanced PCI South Bridge with Ultra ATA/66MHz IDE Controller is a multi-function PCI device implementing a PCI-to-ISA bridge function, a PCI Ultra ATA/66 IDE controller function, a Universal Serial Bus host/hub function, and an Enhanced Power Management function. As a PCI-to-ISA bridge, the SLC90E66 integrates I/O functions found in a common ISA bridge chip, that includes two DMA controllers, two interrupt controllers, an 8254 timer, and a Real Time Clock. The DMA controllers support Type-F data transfers on each of the eight channels. The SLC90E66 also supports PC/PCI and Distributed DMA protocols for PCI based DMA applications. The Interrupt Controllers support Edge or Level sensitive programmable inputs and the use of an external I/O APIC and serial interrupts. The SLC90E66 can be configured to provide chip select decoding for BIOS, RTC, keyboard controller, external microcontroller, and two programmable chip selects. The SLC90E66 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 that used in a PCI/ISA docking station environment.

The SLC90E66 supports two IDE channels for up to four IDE devices in either PIO or Bus Master mode. The SLC90E66 also supports "Ultra ATA/66" synchronous DMA compatible devices for data transfer rates up to 66Mbytes per second. The embedded 32 double word (32x32-bit)deep buffers allow zero wait state PCI burst transfer in either direction.

The SLC90E66 integrates a USB host controller that is Open Host Controller Interface (OHCI) compatible. Two USB ports are implemented in the root hub. The USB controller has been enhanced to support wake-up from a power-on suspend (POS).

The SLC90E66 supports comprehensive power management, including full clock control, device power management for up to 14 devices, global power management 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. System Management Bus (SMBus) host and slave interface logic is integrated for communication with other on-board devices.
