1-8 Overview of the Nuvoton BMC Controller

The Nuvoton

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 conguration, please refer to the
