G120 - How to distinguish between internal and external memory

The G210 uses the LPC1788FET180 chip which has 96kb of internal memory. The module also has 13mb of user available memory. I have some encryption operations that must not use or produce any data that ends up on the external memory. Is this possible to do?

I suggest that you contact GHI directly, and discuss this requirement with them. I suspect that a custom build of the firmware, which does not use the 96kb address space, will be required.

There are all sorts of technical details that have to be understood to answer your question.

@ Mike, right. Got it.
