Is it possible to use a single 1Gb (32Mx32) device with the LPC4350's EMC? The user manual only has Address mapping examples for, 64Mb, 128Mb, 256Mb, and 512Mb. While I know it isn't the same device, I was reading an App Note for the LPC32xx (http://www.nxp.com/documents/application_note/AN10935.pdf). It seems to have address mappings that are similar to the LPC4350 and it supports 1Gb (32Mx32) devices.

Does anyone know if the LPC4350 will work with and be able to address a whole 1Gb (32Mx32) SDRAM chip? I need to get 128MB of RAM, and I am trying to do it with one chip.

Thanks.
