1.5 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 genera-
tor, 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 two 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). Each UART includes a 16-byte send/receive FIFO, a programmable baud
rate generator, complete modem 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 Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management to
reduce power consumption.
1.5.1 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.
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/vir-
tual media emulation. It also provides LPC interface to control Super I/O functions.
The WPCM450 is connected to the network via n external Ethernet PHY module.
The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, and 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 ports for boundary scan and debug
