Synchronous DRAM Controller Module
The following tables provide a more comprehensive, step-by-step way to determine the correct
address line connections for interfacing the MCF5271 to the 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 MCF5271, which is not necessarily the SDRAM port size. For example, if two
1M x 16-bit SDRAMs together form a 1M 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.

Because the device has 24 external address lines, the maximum
SDRAM address size is 128 Mbits.
