When eight cores in C6678 all in work, what is the maximum currents of CVDD and CVDD1?

I cannot find the values in datasheets. Hope to receive your kind help. Thank you!

Summer,

There is a Power Consumption spreadsheet (with a link to an application note in the spreadsheet) in the Product Folder at TMS320C6678 under More Literature. Please use this to input your loading needs to see what the power requirements are.

Summer,

Please keep in mind that case temperature is a very important component to this and you'll want to do thermal analysis such that for your environment and usage that your thermal solution keeps the device at or below the case temp you use in the power spreadsheet.

Best Regards,

Chad
