W83697 -  LPC I/O

1. GENERAL DESCRIPTION 

The W83697UF is evolving product from Winbond's most popular I/O family. They feature a whole 

new interface, namely LPC (Low Pin Count) interface, which will be supported in the new generation 

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 pin counts 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 

W83697UF'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. 

The disk drive adapter functions of W83697UF 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 W83697UF greatly reduces the number of components required 

for interfacing with floppy disk drives. The W83697UF supports four 360K, 720K, 1.2M, 1.44M, or 

2.88M disk drives and data tranufer rates of 250 Kb/s, 300 Kb/s, 500 Kb/s,1 Mb/s, and 2 Mb/s. 

The W83697UF provides four 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. All 

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 W83697UF 

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). 

The W83697UF 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 W83697UF 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. General Purpose Port 1 is designed to be 

functional even in power down mode (VCC is off). 

The W83697UF is made to fully comply with Microsoft? PC98 and PC99 Hardware Design Guide, 

and meet the requirements of ACPI. 

The W83697UF 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. They are very important for a 

entertainment or consumer computer. 

The W83697UF provides Flash ROM interface. That can support up to 4M legacy flash ROM.
