The LPC47B34x 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 62 GPIO pins and ISA IRQ to serial IRQ conversion. The LPC47B34x 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 LPC47B34x incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The LPC47B34x 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 LPC47B34x may be reprogrammed through the internal configuration registers. There are 480 I/O address location options, a Serialized IRQ interface, and three DMA channels.
