Is 6.8V on VPP required during SPotA?
Hi Rofe, yes, if you want to patch OTP on SPoTA, then 6.8V is required on Vpp. If this is not possible, alternatives choices are to use System RAM or rentention RAM or external memory .
In SRAM, system needs to be powered and can only go into extended sleep.
In Retention RAM , system needs to be powered but can go to extended or deep sleep mode
In External memory the sytem can be completely powered off .
Thank you for answer.
