control Super IO functions. The WPCM450R Controller is connected to the network
via an external Ethernet PHY module or shared NCSI connections.
The WPCM450R communicates with onboard components via six SMBus inter-
faces, PECI (Platform Environment Control Interface) buses, and General Purpose
I/O ports.
WPCM450R DDR2 Memory Interface
The WPCM450R supports a 16-bit DDR2 memory module with a speed of up to 220
MHz. For best signal integrity, the WPCM450R provides point-to-point connection.
WPCM450R PCI System Interface
The WPCM450R provides 32-bit, 33 MHz 3.3V PCI interface, which is compliant
with the PCI Local Bus Specification Rev. 2.3. The PCI system interface connects
to the onboard PCI Bridge used by the graphics controller.
