 +1 Good Answer/Helpful		 #155787 - code and data space
Responding to: ???'s previous message
Like the AVR, the 8051 is a Harvard architecture where the code space is separate from the data space. Code space is usually flash. The NMIY board mentions 128K address space - this is actually 64k code and 64k data space.

As Andy suggests, going to an ARM based micro might be advisable since the ARM devices usually have more ram internal to the chip. The Luminary eval boards would suit your budget and there are free compilers and tools.
