| Description |
W83697HG is LPC interface I/O. The disk drive adapter functions of W83697HG 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. W83697HG 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. In addition, W83697HG provides IR functions: IrDA 1.0 (SIR for 1.152K bps) and TV remote IR (Consumer IR, supporting NEC, RC-5, extended RC-5, and RECS-80 protocols).
W83697HG supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Extension FDD Mode and Extension 2FDD Mode are also available through the printer port interface pins.
W83697HG provides a set of flexible I/O control functions to the system designer through a set of General Purpose I/O ports. W83697HG is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide, and meet the requirements of ACPI. W83697HG contains a game port and a MIDI port. The game port is designed to support 2 joysticks and can be applied to all standard PC game control devices. W83697HG provides Flash ROM interface. That can support up to 4M legacy flash ROM.
W83697HG support hardware status monitoring for personal computers. It can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stably and properly. |
