The LPC47U32x 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, MPU401 MIDI support and ISA IRQ to serial IRQ conversion. The part also provides a fan speed control output and a fan tachometer input. The LPC47U32x 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 LPC47U32x incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power modes. The LPC47U32x also incorporates SMBus Controller. The LPC47U32x supports the ISA Plug-andPlay 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 LPC47U32x 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 LPC47U32x does not require any external filter components and is therefore easy to use and offers lower system costs and reduced board area. The LPC47U32x is software and register compatible with SMSC's proprietary 82077AA core.
