TMS320F28379D: Power Up Rise Time

Ed Sanders

Greetings,

I have looked in the Data Manual, but cannot find a spec for the rise time of the power supply. Where should I be looking.

Thank you,

Ed,

Are you asking for something like the below? (Note: This is from a different datasheet)

Hi Hareesh,

Yes. And I think I found it. I was using the wrong search term and finding rates for other things.

Thank you,

Ed,

As I had mentioned, this is from the datasheet for a different device (F280039). Can you please clarify exactly what you were looking for and what you found?

Hi Hareesh,

I was looking for the required power supply slew rates in SPRS880O which is the Data Sheet for the 379D. From your post, I changed my search term to 'ramp' and found section 8.9.1.4 Supply Ramp Rate which shows the min and max rates.
