The EMIF supports a glueless interface to SDRAM devices with the following characteristics:
Figure 13-4 shows an interface between the EMIF and a 2M × 16 × 4 bank SDRAM device, and Figure 13-5 shows an interface between the EMIF and a 512K × 16 × 2 bank SDRAM device. For devices supporting 16-bit interface, refer to Table 13-7 for list of commonly-supported SDRAM devices and the required connections for the address pins.
