Up to 32k of const data and unlimited code is easy. Up to 48k sum of const data and nonbanked code is also easy.
But it is possible to have as mach data as you need. Yes, you can put it to pages. But for new development, especially if you have a lot of data, it is strongly recommended to switch to any of S12X families. Global addressing will easy and speedup paged data accesses. Do you have big >16k tables? - then it is even more recommended to switch to S12X.
