***Info:
GENERAL DESCRIPTION
One of Winbond's popular series of I/O chips, the W83877F integrates a
disk drive adapter, serial port (UART), parallel port, IDE bus
interface, and game port decoder onto a single chip. The W83877F is an
enhanced version of the W83777F, with additional powerful features
such as configurable plug-and-play registers for the whole chip and
infrared support in one of the serial ports.
The disk drive adapter functions of the W83877F 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 W83877F greatly reduces the number of components required for
interfacing with floppy disk drives. The W83877F 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, and 1 Mb/S.
The W83877F 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.
The W83877F supports one PC-compatible printer port. Additional
bidirectional I/O capability is available by hardware control or
software programming. The parallel port also supports the Enhanced
Parallel Port (EPP) and Extended Capabilities Port (ECP).
The W83877F supports two embedded hard disk drive (AT bus) interfaces
and a game port with decoded read/write output. The chip's Extension
FDD Mode and Extension 2FDD Mode allow one or two external floppy disk
drives to be connected to the computer through the printer interface
pins in notebook computer applications.
The Extension Adapter Mode of the W83877F allows pocket devices to be
installed through the printer interface pins in notebook computer
applications according to a protocol set by Winbond, but with upgraded
performance. The JOYSTICK mode allows a joystick to be connected to a
parallel port with a signal switching cable.
The configuration registers support mode selection, function enable/
disable, and power down function selection. Moreover, the conf-
igurable PnP registers are compatible with the plug-and-play feature
in Windows 95 , which makes system resource allocation more efficient
than ever.
