W83627EHF/EF, W83627EHG/EG
1. GENERAL DESCRIPTION
W83627EHF/EHG/EF/EG is an 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
new generation 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. 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 W83627EHF/EHG/EF/EG 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 W83627EHF/EHG/EF/EG greatly reduces the
number of components required for interfacing with floppy disk drives. W83627EHF/EHG/EF/EG
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.
W83627EHF/EHG/EF/EG 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,
W83627EHF/EHG/EF/EG provides IR functions: IrDA 1.0 (SIR for 1.152K bps) .
W83627EHF/EHG/EF/EG supports one PC-compatible printer port (SPP), Bi-directional Printer port
(BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). And
W83627EHF/EHG/EF/EG contains a Game port and a MIDI port. The game port is designed to
support 2 joysticks and can be applied to all standard PC game control devices, they are very
important for a entertainment or consumer computer.
W83627EHF/EHG/EF/EG provides Serial Flash ROM interface. That can support up to 8M bits
serial flash ROM.
W83627EHF/EHG/EF/EG provides 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.
W83627EHF/EHG supports hardware status monitoring for personal computers. It can be used to
monitor several critical hardware parameters of the system, including power supply voltages, fan
speeds, and temperatures, which are very important for a high-end computer system to work stably
and properly. Moreover, W83627EHF/EHG supports the Smart Fan control system, including the
TM TM
"Thermal Cruise " and "Speed Cruise " functions. Smart Fan can make system more stable and
user friendly.
W83627EHF/EHG/EF/EG is made to fully comply with Microsoft◦ Jabse Service Manual Search 2024 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
