Using industrial version for a consumer product

[mjbcswitzerland]

Hi All

At the moment one has to use any chip that one can get one's hands on and this has led to a question about the clock speed that can be used on an industrial grade i.MX RT 1062 part in a consumer product.

The industrial parts are specified over a larger temperature range and, for example, the maximum processor speed is 528MHz instead of 600MHz. Therefore it is clear that if the 528Mz limit is respected the product will be suitable for use across the complete -40°C to °105°C range.
However, what is not clear is whether the parts can still be used at 600MHz if the operation is actually limited to the consumer temperature range of 0°C to °95°C?

Specifically, can an industrial grade part be used without needing to lower the speeds if it is used in a consumer temperature range application or are the industrial grade parts actually slower when used in the consumer temperature range and thus have to be operated at reduced speed?

Thanks in advance for this clarification.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1）Specifically, can an industrial-grade part be used without needing to lower the speeds if it is used in a consumer temperature range application, or are the industrial-grade parts actually slower when used in the consumer temperature range and thus have to be operated at reduced speed?
-- NXP releases the blow two versions of RT106x, the primary purpose is to meet more customer's requirement, so I don't think mix-use is a good idea.
Next, for the indusial version, it'd better not run exceeds the maximum clock frequency: 528 MHz under any conditions.
Hope this is clear.
Have a great day,
TIC

OK - thanks

We will base the design constraints based on this information and run the industrial parts on to their specified speeds, even when the temperature range is restricted to commercial range values.
