In an application a costumer will use an MPC8260 processor and a 256Mbyte SDRAM (4 x MT48LC32M16A2 parallel) via the existing SDRAM interface. The SDRAM will operate at a frequency of 50MHz. (The SDRAM is already controlled in another application with another processor and should be used in this case again if possible.) The "self-refresh" function is important. From the data sheets I could see that the interface of the processor does not provide a CKE pin, which is used by the SDRAM. So the question whether the specified SDRAM is compatible with the MPC8260 SDRAM interface and how the corresponding application would be implemented? Or is there an alternative SDRAM that is more suitable for this purpose? Many thanks in advance.
