Hi,

I am trying to replace the 256 Mbit device MT48LC16M16A2B4-6A XIT with 512 Mb SDRAM with the intention of doubling the capacity. The device from Integrated Silicon Solution Inc 512 Mbit SDRAM IS42/45S16320F appears to fulfil my requirement. 

Has anyone used this memory device (or similar size devices) with RZA1H? 

My concern is the bus access timing setting (Bus State Controller register setting )  for larger devices. 

Any suggestion is much appreciated

Regards

Suresh
