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 95/98
TM
, 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 AMIKEY
TM -
2, Phoenix
MultiKey/42
, 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 configured
to provide a predefined alternate function. General Purpose Port 1 is designed to be functional even in
power down mode (VCC is off).
