**W83977TF WINBOND I/O (Multi I/O) c97
***Info:
GENERAL DESCRIPTION
The W83977TF is an evolving product from Winbond's most popular I/O
chip W83877F --- which integrates the disk drive adapter, serial port
(UART), IrDA 1.0 SIR, parallel port, configurable plug-andplay
registers for the whole chip --- plus additional powerful features:
ACPI, 8042 keyboard controller with PS/2 mouse support, 23 general
purpose I/O ports, full 16-bit address decoding, OnNow keyboard
wake-up, OnNow mouse wake-up.
The disk drive adapter functions of W83977TF 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 into
the W83977TF greatly reduces the number of components required for
interfacing with floppy disk drives. The W83977TF 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 W83977TF 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.
The W83977TF 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 95TM, which makes system resource allocation
more efficient than ever.
W83977TF provides functions that comply with ACPI (Advanced
Configuration and Power Interface), which includes support of legacy
and ACPI power management through SMI or SCI function pins. W83977TF
also has auto power management to reduce 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 is available with optional AMIKEY-2, Phoenix MultiKey/42, or
customer code.
The W83977TF 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.
W83977TF is made to fully comply with Microsoft PC97 Hardware Design
Guide. IRQs, DMAs, and I/O space resource are flexible to adjust to
meet ISA PnP requirement. Moreover W83977TF is made to meet the
specification of PC97's requirement in the power management: ACPI and
DPM (Device Power Management).
Another benifit is that W83977TF has the same pin assignment as
W83977AF, W83977F, W83977ATF. This makes the design very flexible.
