GENERAL DESCRIPTION
W83627THF is a Winbond LPC I/O product. The wide range of functions integrated onto the W83627THF greatly reduces the number of components required for interfacing with floppy disk drives. The W83627THF 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 W83627THF 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 interrupts 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. In addition, the W83627THF provides IR functions: IrDA 1.0 (SIR for 1.152K bps) The W83627THF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP).
