Product Summary

The LPC47M182-NR is a 3.3V (5V tolerant) PC99a/PC2001 compliant Advanced I/O controller for Desktop PCs. The LPC47M182-NR, which implements the Low Pin Count (LPC) interface, includes I/O functionality as well as Motherboard GLUE logic into a 128-pin package. This is space saving solution on the motherboard resulting in lower cost. The LPC47M182-NR also provides 13 general purpose pins, which offer flexibility to the system designer, and two Fan Tachometer Inputs. The LPC47M182-NR’s LPC interface supports LPC I/O and DMA cycles.
