GENERAL DESCRIPTION
The W83627UHG is a member of Nuvoton's Super I/O product line. This family features the LPC (Low
Pin Count) interface. This interface is more economical than its ISA counterpart because it has
approximately forty pins fewer, yet still provides as great performance. In addition, the improvement
allows even more efficient operation of software, BIOS and device drivers.
In addition to providing an LPC interface for I/O, the W83627UHG monitors several critical parameters
in PC hardware, including power supply voltages, fan speeds, and temperatures. In terms of
temperature monitoring, the W83627UHG adopts the Current Mode (dual current source) approach.
The W83627UHG also supports the Smart Fan control system, including “SMART FAN
TM I and SMART
FAN
TM III, which makes the system more stable and user-friendly.
The W83627UHG supports four -- 360K, 720K, 1.2M, 1.44M, or 2.88M -- disk drives and data transfer
rates of 250 Kb/s, 300 Kb/s, 500 Kb/s, 1 Mb/s, and 2 Mb/s. The disk drive adapter supports the
functions of floppy disk drive controller (compatible with the industry standard 82077/ 765), data
separator, write pre-compensation circuit, decode logic, data rate selection, clock generator, drive
interface control logic, and interrupt and DMA logic. Such a wide range of functions integrated into one
W83627UHG greatly reduces the number of required components to interface with floppy disk drives.
The W83627UHG provides six high-speed serial communication ports (UARTs), one of which provides
IR functions IrDA 1.0 (SIR for 1.152K bps). Each UART includes a 16-byte send/receive FIFO, a
programmable baud rate generator, complete modem-control capability, and a processor interrupt
system. All of the UARTs support legacy speeds up to 115.2K bps as well as higher baud rates of
230K, 460K, or 921K bps to support higher speed modems.
The W83627UHG supports the PC-compatible printer port (SPP), the bi-directional printer port (BPP),
the enhanced parallel port (EPP) and the extended capabilities port (ECP).
The W83627UHG provides flexible I/O control functions through a set of 45 general purpose I/O
(GPIO) ports. These GPIO ports may serve as simple I/O ports or may be individually configured to
provide alternative functions.
The W83627UHG supports the SST (Simple Serial Transport) interface and Intel
PECI (Platform
Environment Control Interface).
The W83627UHG fully complies with the Microsoft
PC98 and PC99 Hardware Design Guide and
meets the requirements of ACPI.
The configuration registers inside the W83627UHG support mode selection, function enable and
disable, and power-down selection. Furthermore, the configurable PnP features are compatible with
the plug-and-play feature in Windows 95/98/2000/XP
TM, making the allocation of the system resources
more efficient than ever.
One special characteristic of the Super I/O product line is the separation of the power supply in normal
operation from that in standby operation. Please pay attention to the layout of these two power
supplies to avoid short circuits. Otherwise, the feature will not function.
