LPC84x FlashROM Data retention

[jun1]

HI.

1. Is the flash ROM of the LPC84x NOR type?

2. Does this data retention period mean the life is calculated from the number of read errors that occur as a result of accelerated testing with the temperature turned on with the power on?

3. I think that the probability that the error of the flash ROM occurs in the power ON state changes with the temperature condition, for example, when the standard of Tamb = -40 ° C to +105 ° C is relaxed from -20 ° C to +70 ° C etc., the period is extended Is it?
I would be happy if you could tell me the formula.

# I do not think that English is not good.

Thank you.

Hi 

What do you mean with ROM type NOR, the internal structure? if this is the case this information can not be shared, this is internal information

On the following link, you can see some information about how the data retention is calculated, this is a reference

https://www.nxp.com/docs/en/engineering-bulletin/EB618.pdf

And yes with more temperature range there are more probabilities of failures, but there is not a formula that can be shared

Hi.

I was able to understand the data retention characteristics.

I asked because the LPC series was MIN 10 years.

I understand this matter.

Thank you very much.
