1. GENERAL DESCRIPTION
The W83627HF and W83627F are evolving product from Winbond's most popular I/O family. They
feature a whole new interface, namely LPC（Low Pin Count）interface, which will be supported in the
next generation Intel chip-set. This interface as its name suggests is to provide an economical imple-
mentation of I/O's interface with lower pin count and still maintains equivalent performance as its ISA
interface counterpart. Approximately 40 pin counts are saved in LPC I/O comparing to ISA implemen-
tation. With this additional freedom, we can implement more devices on a single chip as demonstrated
in W83627F/HF's integration of Game Port and MIDI Port.It is fully transparent in terms of software
www.DataSheet4U.comwhich means no BIOS or device driver update is needed except chip-specific configuration.
The disk drive adapter functions of W83627F/HF include a 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. The wide
range of functions integrated onto the W83627F/HF greatly reduces the number of components re-
quired for interfacing with floppy disk drives. The W83627F/HF 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 W83627F/HF provides two high-speed serial communication ports（UARTs）, one of which sup-
ports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a program-
mable baud rate generator, complete modem control capability, and a processor interrupt system.
Both UARTs provide legacy speed with baud rate up to 115.2k bps and also advanced speed with
baud rates of 230k, 460k, or 921k bps which support higher speed modems. In addition, the
W83627F/HF provides IR functions： IrDA 1.0 （SIR for 1.152K bps）and TV remote IR （Consumer
IR, supporting NEC, RC-5, extended RC-5, and RECS-80 protocols）.
The W83627F/HF supports one PC-compatible printer port （ SPP ） , Bi-directional Printer port
（BPP） and also Enhanced Parallel Port （EPP） and Extended Capabilities Port（ECP）. Through
the printer port interface pins, also available are： Extension FDD Mode and Extension 2FDD Mode
allowing one or two external floppy disk drives to be connected.
The configuration registers support mode selection, function enable/disable, and power down function
selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature
demand of Windows 95/98TM, which makes system resource allocation more efficient than ever.
The W83627F/HF provides functions that complies with ACPI （Advanced Configuration and Power
Interface ） , which includes support of legacy and ACPI power management through PME# or
PSOUT# function pins. For OnNow keyboard Wake-Up, OnNow mouse Wake-Up, and OnNow CIR
Wake-Up. The W83627F/HF also has auto power management to reduce the power consumption.
The keyboard controller is based on 8042 compatible instruction set with a 2K Byte programmable
ROM and a 256-Byte RAM bank. Keyboard BIOS firmware are available with optional AMIKEYTM -2,
Phoenix MultiKey/42TM, or customer code.
The W83627F/HF provides a set of flexible I/O control functions to the system designer through a set
of General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually con-
figured to provide a predefined alternate function. General Purpose Port 1 is designed to be functional
even in power down mode（VCC is off）.
The W83627F/HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide.
Moreover W83627F/HF is made to meet the specification of PC98/PC99's requirement in the power
management： ACPI and DPM （Device Power Management）.
