Overview of the Nuvoton WPCM450 Controller
The Nuvoton WPCM450R Controller, a Baseboard Management Controller (BMC),
supports 2D/VGA-compatible Graphic Cores with PCI interface, creating multi-media
virtualization via Keyboard/Video/Mouse Redirection (KVMR). The WPCM450R
Controller is ideal for remote system management.
The WPCM450R Controller interfaces with the host system via PCI connections
to communicate with the graphics cores. It supports USB 2.0 and 1.1 for remote
keyboard/mouse/virtual media emulation. It also provides LPC interface support to
control Super IO functions. The WPCM450R Controller is connected to the network
via an external Ethernet PHY module or shared NCSI connections.
The WPCM450R communicates with onboard components via six SMBus inter-
faces, PECI (Platform Environment Control Interface) buses, and General Purpose
I/O ports.
WPCM450R DDR2 Memory Interface
The WPCM450R supports a 16-bit DDR2 memory module with a speed of up to 220
MHz. For best signal integrity, the WPCM450R provides point-to-point connection.
WPCM450R PCI System Interface
The WPCM450R provides 32-bit, 33 MHz 3.3V PCI interface, which is compliant
with the PCI Local Bus Specification Rev. 2.3. The PCI system interface connects
to the onboard PCI Bridge used by the graphics controller.
Other Features Supported by the WPCM BMC Controller
The WPCM450R supports the following features:
•
IPMI 2.0
•
Serial over LAN
•
KVM over LAN
•
LAN Alerting-SNMP Trap
