W83877TF WINBOND I/O W83877TF WINBOND I/O GENERAL DESCRIPTION The W83877TF is an enhanced version 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 Plugand-Play registers for the whole chip --- plus additional powerful features: ACPI / legacy power management, serial IRQ, and IRQ sharing. The disk drive adapter functions of W83877TF include a floppy disk 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, interrupt and DMA logic. The wide range of functions integrated into the W83877TF greatly reduces the number of components required for interfacing with floppy disk drives. The W83877TF 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 W83877TF 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. One of the UARTs support infrared (IR) IrDA1.0. Both UARTs provide legacy speed with baud rate up to 115.2K and provide advanced speed with baud rate up to 230k, 460k, and 921k bps which support higher speed Modems. The W83877TF supports one PC-com.
