TMS320C5517: Maximum power consumption in each power lines

Kaka

Part Number: TMS320C5517

Hi TI Experts,

Please let me confirm the following question.
[Question]
Would you please provide the maximum current consumption values on each power lines?
My customer request to us to provide those data in order to design their power block.
I checked the datasheet, but I could not find this specification. Also I know that TI provide the power estimation sheet at TI wiki but it seems the result values are typical.

If you have any questions, please let me know.
Best regards.

Hi,

You can use the power spreadsheet from this link:
processors.wiki.ti.com/.../35_Power_Consumption_Summary
to evaluate the consumption of your device.

Hi

I know that TI provide the estimation tool as below link but this data is typical use case,right??
processors.wiki.ti.com/.../TMS320C5517_Power_Consumption_Summary

My request is to provide the maximum current consumption data on each power lines.

Best regards.

Hi Kaka,

You can input the maximum frequencies possible for each clock. Use maximum voltage (1.4V) for cvdd, and input 100% utilization of the modules and you should see the maximum current consumption of the power rails.

Hi Yordan

Is this result considering the variations of devices?

Best regards.

Hi,

What do you mean variations of devices?
This shows the consumption when the device is fully utilized & works at maximum clock speed (opp).

Hi

It mean "device mismatch" or variation from device to device. Does it make sense?

I am not sure, but variation from device to device should be minimal (if any), so, in my opinion, these max values can be used.

Yes the c5517 power estimation spreadsheet comprehends the process (device to device) variation and provides data based on strong process units.
