Thanks for the info. But how come there are other AT91 chips with 2M Flash and 256KB RAM?
Basically I am looking for a highly integrated and low-cost solution. I think a SOC approach is a great from a reliability and manufacturing point of view. External SRAM also tends to be expensive especially towards the end of its production life a few years from now, which could become a problem for us.
I need a lot of flash for storing about 400KB of configuration data. So an external Flash might be a decent solution.
