Interface Recommendations
The following tables provide a more comprehensive, step-by-step way to determine the correct address line
connections for interfacing the MCF523x to SDRAM. To use the tables, find the one that corresponds to the
number of column address lines on the SDRAM and to the port size as seen by the MCF523x, which is not
necessarily the SDRAM port size. For example, if two 1M x 16-bit SDRAMs together form a 2M x 32-bit
memory, the port size is 32 bits. Most SDRAMs likely have fewer address lines than are shown in the tables,
so follow only the connections shown until all SDRAM address lines are connected.
