Note: The chip is part of a family of LPC chips (LPC47M13x, LPC47M14x, and LPC47M15x). The first 100 pins of
these chips are pin compatible, which adds more flexibility for the board designer. In addition, a board designed for
the LPC47M14x can also support the LPC47M13x with little or no changes made to the board design.
