Winbond LPC I/O
All product names, trademarks, brands and logos used on this site are the property of their respective owners. The depiction, description or sale of products featuring these names, trademarks, brands and logos is for identification purposes only and is not intended to indicate any affiliation with or authorization by any rights holder.
GENERAL DESCRIPTION
The W83627HF and W83627F are 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 next generation 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 pin counts are saved in LPC I/0 comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83627F/HF'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 W83627FHF 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 W83627F/HF greatly reduces the number of components required for interfacing with floppy disk drives. The W83627F/HF 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 2Mb/s.
The W83627F/HF provides two high-speed serial communication ports (UARTs) , one of which sup-ports 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 W83627F/HF 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 W83627F/HF 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 al1owing one or two external f1oppy 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 W83627F/HF 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, and OnNow CIR Wake-Up.The W83627F/HF 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 AMIKEY Phoenix MultiKey/42 TM, or customer code.
The W83627F/HF provides a set of flexible I/O control functions to the system designer through a set of General Purpose I/O ports. These GPI0 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 W83627F/HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide. Moreover W83627F/HF is made to meet the specification of PC98/PC99's requirement in the power management: ACPI and DPM (Device Power Management) .
The W83627F/HF 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.
Only the W83627HF 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 proper1y.
