I am working on a microcontroller design using the LH79520. I would like to use the Micron MT48LC4M32B2 SDRAM which is 128Mb with a 32bit data path.
However in looking at the Sharp user manual, the sdram controller does not have a configuration listed for a 4Mx32 memory. The closest is 2Mx32. It looks like the 2Mx32 configuration should work for a 4Mx32, but I can not be certain.
I sent an email to Sharp MA asking if there is a valid configuration for 4Mx32, but have not received a reply.
Has anyone else attempted to use a 4Mx32 SDRAM with the LH79520 or gotten an answer from Sharp if this will work.
