W83637HF
1. GENERAL DESCRIPTION
The 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 Stick^TM reader interface. The Memory Stick^TM 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 95/98^TM, 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 AMIKEY^TM -2,
Phoenix MultiKey/42^TM, or customer code.
