QorIQ T2080 Processor Power calculation/Estimation queries

[KLN]

Hi,

We are going to use QorlQ T2080 Processor.

For Power calculation of the processor, Any excel/document is available to use?

Also, we are planning to use PCIe interface to NVMe SSD. As Processor will be root-complex and  SSD will be End nodes, End nodes to be powered up and should be up before the root-complex, Should power sequence need to be taken care or processor will handle this??

And Processor will be End-point in another use case.

Hi @KLN,

Refer to section# 3.4 in the T12080 datasheet and specifically table# 8 for T2080 I/O power dissipation.

Hi @mrudangshelat-13 
I understand that Datasheet has mentioned power details in the datasheet.

I was specifically asking for the Excel is available for ease of use.

Also Please note that I have asked about SSD related question also.

[mrudangshelat-13]

Hi @KLN,

There is no such excel available.

Regarding the SSD related question, I am working on it and I will let you know once I have any findings.

Hi @mrudangshelat-13 

Thanks for your response.

Please let us know at the earliest. I do see that responses are very slow.

Hi @KLN,

I apologize for the delay as I was facing some server glitches since last week.

I would suggest to implement a power switching circuit for the powering up the end node in order to avoid unwanted voltage to processor(root complex) from the end node when end node is powered up before the processor.

One more query on T2080 Power related,

Are there any requirement of Sequencing of power?

[mrudangshelat-13 · Accepted solution]

Hi @KLN,

The required power sequencing is mentioned in the section# 3.2 of T2080 datasheet.
