1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock generator,
drive interface control logic and interrupt and DMA logic. The wide range of functions
integrated onto the Super I/O greatly reduces the number of components required
for interfacing with floppy disk drives. The Super I/O supports 360 K, 720 K, 1.2
M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or
1 Mb/s. It also provides two high-speed, 16550 compatible serial communication
ports (UARTs). 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 Configuration
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 Winbond WPCM450 Controller
The Winbond WPCM450 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 WPCM450 Controller is ideal for
legacy-reduced server 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.
The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, Platform Environment Control Interface (PECI) buses, and General
Purpose I/O (3SGPIO) ports.
The WPCM450 also includes the following features:
One X-Bus parallel interface for expansion I/O connections
•
Three ADC inputs, Analog and Digital Video outputs
•
Two serial for boundary scan and debug
•
