Winbond I/o

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.
