The Winbond Hermon WPCM450 Controller interfaces with the host system via a
PCI interface 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).
