SDRAM SDR Connections
Figure 4 shows a block diagram of the connections between the MCF547x and SDR SDRAM components.
SDR design requires special timing consideration for the SD_DQS[3:0] signals. For reads from DDR
SDRAMs, the memory will drive the DQS pins so that the data lines and DQS signals have concurrent
edges. The MCF547x SDRAMC is designed to latch data 1/4 clock after the SD_DQS[3:0] edge. For DDR
SDRAM, this ensures that the latch time is in the middle of the data valid window.
The MCF547x also uses the SDDQS[3:0] signals to determine when read data can be latched for SDR
SDRAM; however, SDR memories do not provide DQS outputs. Instead the SDRAMC provides an
SDRDQS output that is routed back into the controller as SDDQS[3:0]. The SDRDQS signal should be
routed such that the valid data from the SDRAM reaches the MCF547x at the same time or just before the
SDRDQS reaches the SDDQS[3:0] inputs. The appropriate delay for SDRDQS can be generated using a
buffer or driver, as shown in Figure 4. Using a buffer or driver will also ensure that the SDRDQS signal can
drive all four of the MCF547x’s SDDQS[3:0] inputs.
