Running Blackfin at High Frequency
Hi,
whether the following statement is true?
The internal voltage regulation feature is not available on any of the 600 MHz speed grade models or automotive grade models.External voltage regulation is required to ensure correct operation of these parts.

Yes, the statement ist true. The internal voltage regulator is NO feature on all automotive parts or 600MHz speed grade parts.
Hi
it means instead of using VROUT signal to generate the VDDINT, we need to generate the VDDINT signal from external with out the help of VROUT.
Is my understanding is correct?
Hi,
Yes. Your understanding is correct if you only want to run at 600MHz.
However, if you want to be able to dynamically change your power/frequency, then you may still want to use VROUT to control the external voltage regulator.
