DescriptionThe W83637HF is the new generation of Winbond's LPC I/O products. It is an evolving product from Winbond's most popular LPC I/O chip W83627HF which integrates the disk driver adapter, serial port (UART), keyboard controller (KBC), SIR, CIR, game port, MIDI port, hardware monitor, ACPI, On Now Wake-Up plus additional new features: the Smart Card reader interface and Memory Stick TM reader interface.
The Smart Card application is gaining more and more attention; it provides a very high-grade security and convenience in Internet transaction, banking, telephony, electronic payments, etc. The W83637HF supports 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. W83637HF provides a minimum external components and lowest cost solution for smart card applications.
The W83637HF implements a standard Memory StickTM reader interface. The Memory StickTM has been a new mainstream media for storing and transferring data. It's ultra-small size and high storage capacity make it can be used in very wide variety products, including the Audio, Video and PC.
The disk drive adapter functions of W83637HF 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 W83637HF greatly reduces the number of components required for interfacing with floppy disk drives. The W83637HF 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 W83637HF 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 interrupts 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 W83637HF 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 W83637HF 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 W83637HF 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 W83637HF 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 AMIKEYTM -2, Phoenix MultiKey/42TM, or customer code.
