Hello Group, I'm relatively new at this and am working on a new project. I'm currently using a 18F452 and know about the 18F4520 as its new replacement. I don't know how much memory Ill need and would like to prototype using a similar part with the most program memory available. Looking at the available parts, I happened across the 18F4685 but have a question relating to Flash vs Enhanced Flash. I'm currently using a clone ICD2 for programming and debugging. Will the ICD2 work with a non-Enhanced Flash part like the 4685? Is there a document which details the differences between the two types of Flash? I'd like to know what capabilities I'm losing with a non-Enhanced Flash part.
