GENERAL DESCRIPTION
One of Winbonds 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.
