Can somebody tell me how often i can write to the internal flash of the xc167 controller? i'm doing a lot of tests and therefore i'm programming the flash very often and right now i am a little bit afraid that after too many write procedures the controller doesn't run properly. is there specified limit? Regards Chris
The endurance is specified by Infineon with 100 times. However this is for the full temparture range and 10+ year lifetime. I guess your question is: how often can I reprogram the device for debugging proposes. We have several test boards that we have reprogrammed many 1000 times - NO PROBLEM SO FAR. Also non of our customers has ever reported that a Flash device went dead due to reprogramming. So practical you can reprogram the device many 1000 times (but I would not ship such a test board to end-users)
