W83627THF is a Winbond LPC I/O product. It integrates the following major peripheral functions in a chip: the disk driver adapter (FDC), Serial port (UART), Parallel port (SPP/EPP/ECP), Keyboard controller (KBC), SIR, Game port, MIDI port, Hardware Monitor, ACPI, On Now Wake-Up features. The disk drive adapter functions of W83627THF 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 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). Through the printer port interface pins, also available are: Extension FDD Mode and Extension 2FDD Mode allowing one or two external floppy disk drives to be connected. The configuration registers support mode selection, function enable/disable, and power down function selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature demand of Windows 95/98TM, which makes system resource allocation more efficient than ever. The W83627THF provides functions that complies with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through PME# or PSOUT# function pins. For OnNow keyboard Wake-Up, OnNow mouse Wake-Up. The W83627THF also has auto power management to reduce the power consumption. The keyboard controller is based on 8042 compatible instruction set with a 2K Byte programmable ROM and a 256-Byte RAM bank. Keyboard BIOS firmware are available with optional AMIKEYTM -2, Phoenix MultiKey/42TM, or customer code. The W83627THF provides a set of flexible I/O control functions to the system designer through a set of General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually configured to provide a predefined alternate function.
