The device supports 16-bit SDRAM in addition to the asynchronous memories listed in Section 6.10.1. It has a single SDRAM chip select (EMA_CS[0]). SDRAM configurations that are supported are:
Additionally, the SDRAM interface of EMIFA supports placing the SDRAM in Self Refresh and Powerdown Modes. Self Refresh mode allows the SDRAM to be put into a low power state while still retaining memory contents; since the SDRAM will continue to refresh itself even without clocks from the device. Powerdown mode achieves even lower power, except the device must periodically wake the SDRAM up and issue refreshes if data retention is required.
Finally, note that the EMIFA does not support Mobile SDRAM devices.
Table 6-19 shows the supported SDRAM configurations for EMIFA.
