PRELIMINARY
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
implementation 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
implementation. 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 which 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 required 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 supports
serial Infrared communication. 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 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

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 configured
to provide a predefined alternate function. General Purpose Port 1 is designed to be functional even in
power down mode (VCC is off).
