W83627SF General Description

The W83627SF is the new generation of Winbond's LPC I/O products. It features a whole new interface, namely LPC (Low Pin Count) interface, which is supported in mainstream Intel chip-set. This interface as its name suggests is to provide an economical implementation of I/O's interface with lower pin count and still maintains equivalent performance as its ISA interface counterpart. Approximately 40 pins are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83627SF's integration of Game Port and MIDI Port. It is fully transparent in terms of software which means no BIOS or device driver update is needed except chip-specific configuration.

As Smart Card application is gaining more and more attention, W83627SF also implements a smart card reader interface featuring Smart wake-up function. This smart card reader interface fully meets the ISO7816 and PC/SC (Personal Computer/Smart Card Workgroup) standards. W83627SF provides a minimum external components and lowest cost soultion for smart card applications.

The disk drive adapter functions of W83627SF 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 W83627SF greatly reduces the number of components required for interfacing with floppy disk drives. The W83627SF 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 W83627SF 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. 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 W83627SF 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).
