1-8 Overview of the Nuvoton BMC Controller
The Nuvoton
SM
WPCM150 is a combined Baseboard Management Controller and
2D/VGA-compatible Graphics Core with PCI interface, Virtual Media and Keyboard,
and a Keyboard/Video/Mouse Redirection (KVMR) module.
The WPCM150 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 an LPC interface to control Super I/O func-
tions and connects to the network via an external Ethernet PHY module or shared
NCSI connections.
The Nuvoton BMC communicates with onboard components via six SMBus in-
terfaces, fan control, Platform Environment Control Interface (PECI) buses, and
General Purpose I/O (T-SGPIO) ports.
There are two different versions of the Nuvoton BMC chip that are used in this prod-
uct series. The Nuvoton WPCM150 (Manufacturer P/N WPCM150GA0BX5) which
includes all of the features above, is the chip installed in the X8SIA motherboard.
Another version, the Nuvoton WPCM450 (Manufacturer P/N WPCM450RA0BX)
also has all the features as described above plus IPMI 2.0 support. This particular
chip is installed in the X8SIA-F motherboard model.
Note: For more information on IPMI conguration, please refer to the
