Notes:
1. “n” is a Row/Column PIC number
2. The DDR interface is designed for memories that support one DQS strobe per eight bits of
data. In some packages, all the potential DDR data (DQ) pins may not be available.
3. PIC numbering definitions are provided in the “Signal Names” column of the Signal Descrip-
tions table.
