Figure 8. FlexBus Write Timing
5.7
SDRAM Bus
The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports standard SDRAM or
double data rate (DDR) SDRAM, but it does not support both at the same time.
5.7.1
SDR SDRAM AC Timing Characteristics
The following timing numbers indicate when data is 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 remain supplied to the device
for each data beat of an SDR read. The processor accomplishes this by asserting a signal named SD_SDR_DQS during read
cycles. Care must be taken during board design to adhere to the following guidelines and specs with regard to the
SD_SDR_DQS signal and its usage.
