W83627DHG-P/W83627DHG-PT
1. GENERAL DESCRIPTION
The W83627DHG-P 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, in that 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 W83627DHG-P monitors several critical
parameters in PC hardware, including power supply voltages, fan speeds, and temperatures. In terms
of temperature monitoring, the W83627DHG-P adopts the Current Mode (dual current source)
TM
approach. The W83627DHG-P also supports the Smart Fan control system, including S

The W83627DHG-P supports four -- 360K, 720K, 1.2M, 1.44M, or 2.88M -- disk drive types 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
W83627DHG-P greatly reduces the number of required components to interface with floppy disk
drives.
The W83627DHG-P provides two 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. Both UARTs support legacy speeds up to 115.2K bps as well as even higher baud
rates of 230K, 460K, or 921K bps to support higher speed modems.
The W83627DHG-P 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 W83627DHG-P provides a bridge of the Low Pin Count interface to Serial Peripheral Interface
(SPI) that supports up to 8M bits serial flash ROM. The W83627DHG-P provides flexible I/O control
functions through a set of 40 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 W83627DHG-P supports the SST (Simple Serial Transport) interface and Intel
PECI (Platform
Environment Control Interface).
The W83627DHG-P fully complies with the Microsoft© PC98, PC99 and PC2001 System Design
Guides and meets the requirements of ACPI.
The configuration registers inside the W83627DHG-P support mode selection, function enable and
disable, and power-down selection. Furthermore, the configurable PnP features are compatible with
TM
the plug-and-play feature in Windows 95/98/2000/XP
, 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.
In addition to W83627DHG-P, there is W83627DHG-PT. W83627DHG-PT is exactly the same as
W83627DHG-P, except the IC operation temperature. W83627DHG-PT supports industrial standard,
which means the IC operating temperature ranges from -40℃ to 85℃. W83627DHG-P supports
commercial standard, which means the IC operating temperature ranges from 0℃ to 70℃.
