15.2.3.3 Interfacing Example
The tables in the previous section can be used to configure the interface in the following example. To
interface one 2M x 32-bit x 4 bank SDRAM component (8 columns), use the connections shown in
Table
15.2.3.4 Burst Page Mode
SDRAM can efficiently provide data when an SDRAM page is opened. As soon as SCAS is issued, the
SDRAM accepts a new address and asserts SCAS every CLKOUT for as long as accesses occur in that
page. In burst page mode, there are multiple read or write operations for every
SDRAM if the requested transfer size exceeds the port size of the associated SDRAM. The primary cycle
of the transfer generates the
or
next access.
