W83627EHF is an evolving product from Winbond's most popular I/O family. They feature a whole new interface, namely LPC (Low Pin Count) interface. The disk drive adapter functions of W83627EHF 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 W83627EHF greatly reduces the number of components required for interfacing with floppy disk drives. W83627EHF provides two high-speed serial communication ports (UARTs), one of which supports serial Infrared communication. In addition, W83627EHF provides IR functions: IrDA 1.0 (SIR for 1.152K bps). W83627EHF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). And W83627EHF contains a Game port and a MIDI port. W83627EHF provides Serial Flash ROM interface. That can support up to 8M bits serial flash ROM. W83627EHF provides flexible I/O control functions to the system designer through a set of General Purpose I/O ports. W83627EHF supports 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. Moreover, W83627EHF supports the Smart Fan control system, including the "Thermal Cruise" and "Speed Cruise" functions. Smart Fan can make system more stable and user friendly. W83627EHF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide, and meet the requirements of ACPI.
