More than 16MB SDRAM

Hello!Our old designs always used the maximum directly supported SDRAM of 16MByte but we need more than that. 64MByte of SDRAM would be useful. >muscleman said: >It is my understanding that the internal NETA50 SDRAM >controller only supports SDRAM with 8 >CAS lines.

Is there a reference design for such a circuit and for the right SDRAM controller settings? I want to use the Micron MT48LC16M16A2TG-75IT chips. Ciao Peter
