I was looking for space grade rad-hard microcontroller. It is widely mentioned that microcontrollers are limited in their usage in space domain. The reason being that due to high cosmic radiation there could be adverse effects on the flash, thereby corrupting the code stored. So, I decided to look at FPGAs as they are much more stable (vis-a-vis radiation effects). Is it possible that I select an FPGA and program a softcore that can fulfill my microcontroller needs ?
My present board has the LPC4337 dual cortex MCU. Is there any similar chips that are rad-hard ? Most of the rad-grad MCUs are from Atmel,ST and a couple of vendors (intersil,surprisingly). But not many are ARM compatible.
Atmel has a SPARC core, which again causes software migration issues. Are ARM cortexes used in space ? I would appreciate any pointers in this direction please.
