Figure 11. Flexbus Write Timing

SDRAM Bus
The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports
either standard SDRAM or double data rate (DDR) SDRAM, but it does not support both at the same time.
5.8.1
SDR SDRAM AC Timing Characteristics
The following timing numbers indicate when data will be latched or driven onto the external bus, relative
to the memory bus clock, when operating in SDR mode on write cycles and relative to SD_DQS on read
cycles. The device’s SDRAM controller is a DDR controller that has an SDR mode. Because it is designed
to support DDR, a DQS pulse must still be supplied to device for each data beat of an SDR read. Te
processor accomplishes this by asserting a signal named SD_DQS during read cycles. Care must be taken
during board design to adhere to the following guidelines and specs with regard to the SDR_DQS signal
and its usage.
