An Overview of the Nuvoton WPCM 450 BMC Controller

The Nuvoton WPCM450 Controller, a Baseboard Management Controller (BMC),
supports the 2D/VGA-compatible Graphics Core with support of PCI interface, multi-
media virtualization, and Keyboard/Video/Mouse Redirection (KVMR) modules. The
WPCM450 Controller is ideal for server management platforms.
The WPCM450 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 WPCM450 is connected to the network via an external Ethernet PHY module
or shared NCSI connections.
The WPCM450 communicates with onboard components via six SMBus interfaces,
Platform Environment Control Interface (PECI) buses, and General Purpose I/O
ports.

WPCM450 DDR2 Memory Interface

The WPCM450 supports a 16-bit DDR2 memory module with a speed of up to
220 MHz. The motherboard supports 128 MB memory that is shared between the
BMC and onboard graphics card. For best signal integrity, the WPCM450 provides
point-to-point connection.

WPCM450 PCI System Interface

The WPCM450 provides 32-bit, 33 MHz 3.3V PCI interface, which is compliant with
the PCI Local Bus Specifi cation Rev. 2.3. The PCI system interface connects to the
onboard PCI Bridge and is used by the graphics controller.

Other Features Supported by the WPCM BMC Controller

The WPCM450 supports the following features:
•
IPMI 2.0
•
Serial over LAN
•
KVM over LAN
