control capability and a processor interrupt system. Both UARTs provide legacy
speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud
rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.
1-8 Overview of the Nuvoton WPCM450R Controller (For
X8DTL-3F/X8DTL-iF Only)
The Nuvoton WPCM450R Controller is a Baseboard Management Controller
(BMC) that supports the 2D/VGA-compatible Graphics Core with the PCI interface,
Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With
blade-oriented Super I/O capability built-in, the WPCM450R Controller is ideal for
legacy-reduced server platforms.
The WPCM450R interfaces with the host system via a PCI interface to commu-
nicate 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 WPCM450R is connected to the network via an external Ethernet
PHY module.
The WPCM450R communicates with onboard components via six SMBus inter-
faces, fan control, and Platform Environment Control Interface (PECI) buses.
