The Winbond WPCM450 Controller interfaces with the host system via a PCI inter-
face to communicate with the Graphics core. It supports USB 2.0 and 1.1 for remote
keyboard/mouse/virtual media emulation. It also provides LPC interface to control
Super IO functions. The Winbond WPCM450 BMC is connected to the network via
an external Ethernet PHY module.
The Winbond WPCM450 BMC communicates with onboard components via
six SMBus interfaces, fan control, and Platform Environment Control Interface
(PECI).
