Hello All,

 

I currently in the hardware design stage for one of our new requirement. The DSC that I selected for the design is MC56F8357.

 

I want to have more memory support through the External memory Interface, Probably a NOR Flash for program storage and PSRAM for data processing. Could you please assist me in the design phase? Any reference documents is available?

 

Can I interface the DSC directly to the parallel NOR Flash and the PSRAM over the same bus or there will be need for buffer circuits for bus loading? I have attached the schematics for your reference. I also would like to know whether PSRAM interface will work with the DSC or only SRAM will work? Since the PSRAM has the same interfacing with inbuilt clocking circuits I considered PSRAM for my requirement.

 

Your help will be much appreciated.

 

Regards,

Tom
