I/O Interface Controller - SOYO SY-6VBA133-B User Manual

Motherboard Description
extended 256 byte CMOS RAM, integrated master mode enhanced IDE
controller with full scatter/ gather capability and extension to UltraDMA-
33/66 for 33/66 MB/sec transfer rate, integrated USB interface with root
Hub and two function ports with built-in physical layer transceivers,
Distributed DMA supports, and On Now/ ACPI compliant advanced
configuration and power management interface.
For sophisticated power management, the Apollo Pro133 provides
independent clock stop control for the CPU/SDRAM, PCI, and AGP buses
and 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 VT82C596B south bridge
chip, a complete power conscious PC motherboard can be implemented
with no external TTLs.
The Apollo Pro133 chipset is ideal for high performance, high quality,
high energy efficient and high integration desktop and notebook AGP /
PCI / ISA computer systems.
