Hi Tera,

Most 8052 derivatives handle code size greater than 64K by using code banking. This requires use of some port pins to address the required number of banks. A good compiler makes use of this less painful than it would otherwise be.

I would imagine that there are other 8052 derivatives which can handle large code size more efficiently...I haven't used them but I'd start by looking at parts by Cynal or Triscend. There are parts links here and a parts compare on Keil's website.
