General Description
LPC47U33x General Description
`The LPC47U33x* is a 3.3V PC99 compliant Enhanced Super I/O controller. The LPC47U33x 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 37 GPIO pins, a dual game port interface, MPU- 401 MIDI support and ISA IRQ to serial IRQ conversion. The part also provides a fan speed control output and a fan tachometer input.
`The LPC47U33x incorporates a keyboard interface, SMSC's true CMOS 765B floppy disk controller, advanced digital data separator, one 16C550A compatible UART, one MPU-401 MIDI UART, one Multi-Mode parallel port which includes ChiProtect circuitry plus EPP and ECP , and Intelligent Power Management including ACPI, SMI and PME support. 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 UART is compatible with the NS16C550A. The parallel port is compatible with IBM PC/AT architecture, as well as IEEE 1284 EPP and ECP. The LPC47U33x incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power modes. The LPC47U33x also incorporates SMBus Controller.
`The LPC47U33x supports the ISA Plug-and- Play Standard (Version 1.0a) and provides the recommended functionality to support Windows '95 and PC99. The I/O Address, DMA Channel and Hardware IRQ of each logical device in the LPC47U33x may be reprogrammed through the internal configuration registers. There are 480 I/O address location options, a Serialized IRQ interface, and three DMA channels. The LPC47U33x does not require any external filter components and is therefore easy to use and offers lower system costs and reduced board area. The LPC47U33x is software and register compatible with SMSC's proprietary 82077AA core.

Note: Stresses above those listed above could cause permanent damage to the device. This is a stress rating only and functional operation of the device at any other condition above those indicated in the Normal Operation sections of this specification is not implied.
Note: When powering this device from laboratory or system power supplies, it is important that the Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp circuit be used.
