Hello,

I have been investigating PSoC3 for corrupt user flash after power is cycled. Investigations show that PSoC1 had a sensitivity to voltage spikes and flash was corrupted and even erased completely. CY8C3244LTI-123 is having the same issue. Is there something hardware or software wise to fix this issue.

 

Thank you for your help.

Hardware-wise you can ensure that there are no voltage spikes (proper decoupling caps, ESD/over-voltage protection before the LDO). Software-wise you can do double-buffering so you don't overwrite existing data on updates. When power gets lost during a write there is not much you can do.
