The EMIF module supports 16-bit/32-bit SDRAM in addition to the asynchronous memories listed in Section 11.1.3.1. The EMIF module has a single SDRAM chip select. SDRAM configurations that are supported are:
Additionally, the EMIF supports placing the SDRAM in self-refresh and power-down modes. The self-refresh mode allows the SDRAM to be put in a low-power state while still retaining memory contents, since the SDRAM continues to refresh itself even without clocks from the microcontroller. The power-down mode achieves even lower power, except the microcontroller must periodically wake up and issue refreshes if data retention is required.
Note that the EMIF module does not support mobile SDRAM devices.
