Description

The SMSC LPC47N227 is a 3.3V PC 99 and ACPI 1.0b compliant Super I/O Controller.  The LPC47N227 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 also includes 29 GPIO pins. 

 
The LPC47N227 incorporates SMSC's true CMOS 765B floppy disk controller, advanced digital data separator, 16-byte data FIFO, two 16C550 compatible UARTs, one Multi-Mode parallel port with ChiProtect circuitry plus EPP and ECP support and one floppy direct drive support.  The LPC47N227 does not require any external filter components, is easy to use and offers lower system cost and reduced board area. The LPC47N227 is software and register compatible with SMSC's proprietary 82077AA core.
