The BGA pinout of from page 1-4 seems to contradict the package drawing on page A-1.  Can you help clarify the pinout?

  • Both diagrams are correct. Unfortunately, they use a different numbering convention. The drawing in Appendix A is using rows (alpha) and columns (numeric) whereas Page 1-4 simply numbers around the edges.
    Page 1-4 is a top down view and has the correct pin numbering. Appendix A is a generic BGA using a different numbering system. So, pin 2A from appendix A would correspond to pin 32 on Page 1-4.
