GENERAL DESCRIPTION

The LPC47B37x* is a 3.3V PC99 compliant

Super I/O controller. The LPC47B37x

implements the LPC interface, a pin reduced ISA

interface which provides the same or better

performance as the ISA/X-bus with a substantial

savings in pins used. The part provides 39 GPIO

pins, an SMBus controller and ISA IRQ to serial

IRQ conversion. The part also provides a fan

speed control output and a fan tachometer input.

The LPC47B37x incorporates a keyboard

interface, SMSC's true CMOS 765B floppy disk

controller, advanced digital data separator, two

16C550 compatible UARTs, one Multi-Mode

parallel port which includes ChiProtect circuitry

plus EPP and ECP, and Intelligent Power

Management. The true CMOS 765B core

provides 100% compatibility with IBM PC/XT and

PC/AT architectures in addition to providing data

overflow and underflow protection. The SMSC

advanced digital data separator incorporates

SMSC's patented data separator technology,

allowing for ease of testing and use. The on-chip

UARTs are compatible with the NS16C550. The

parallel port is compatible with IBM PC/AT

architecture, as well as IEEE 1284 EPP and

ECP.

The LPC47B37x incorporates

sophisticated power control circuitry (PCC). The

PCC supports multiple low power down modes.

The LPC47B37x supports the ISA Plug-and-Play

Standard (Version 1.0a) and provides the

recommended functionality to support Windows

'95/’98 and PC99. The I/O Address, DMA

Channel and Hardware IRQ of each logical

device in the LPC47B37x may be reprogrammed

through the internal configuration registers.

There are 480 I/O address location options, a

Serialized IRQ interface, and three DMA

channels.
