On page 54 of the T1022 datasheet it states that:
"Only 300,000 POR cycles are permitted per lifetime of a
device. Note that this value is based on design estimates and is
I have a few questions about this.
What is a POR cycle? is it when all the power rails powered up then down or is it when the device is reset using PORESER_B?
If it is the latter does this mean the device will be lifed if it enters a reset loop (watchdog fault, boot loop etc.) for an extended period of time?
As this is a preliminary value is there a more up to date value available?
