Motherboard Description

SY-7VCA

Dynamic CKE control for powering down of the SDRAM. A separate suspend-well plane is implemented for the SDRAM control signals for Suspend-to-DRAM operation. Coupled with the VT82C686A south bridge chip, a complete power conscious PC motherboard can be implemented with no external TTLs.

The Via 694X chipset is ideal for high performance, high quality, high energy efficient and high integration desktop and notebook AGP / PCI / ISA computer systems.

ØVT82C686A

The VT82C686A PSIPC (PCI Super-I/O integrated Peripheral Controller) is a high integration, high performance, power-efficient, and high compatibility device that supports Intel and non-Intel based processor to PCI bus bridge functionality to make a complete Microsoft PC99- compliant PCI/ISA system In addition to complete ISA extension bus functionality, the VT82C686A includes standard intelligent peripheral controllers:

1)Master mode enhanced IDE controller with dual channel DMA engine and interlaced dual channel commands. Dedicated 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 VT82C686A also supports the UltraDMA-33 standard to allow reliable data transfer rates up to 33MB/sec throughput. The VT82C686A also supports the UltraDMA-66 standard. The IDE controller is SFF-8038I v1.0 and Microsoft Windows-family compliant.

2)Universal Serial Bus controller that is USB v1.1 and Universal HCI v1.1 compliant. The VT82C686A includes the root hub with four 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 non-USB-aware operating system
