TMS320C6652: C6652 power consumption / power dissipation at fCPU

Part Number:TMS320C6652

Hello,

My customer asked me whether the part requires a heatsink if they set fCPU=200MHz.

Aside from the heatsink, here we would like to discuss about the power dissipation only.
I wanted to use sprm676.zip:[C6652_Power_Spreadsheet_Rev_1_0.xlsm], but it doen't accept fCPU<500MHz, so could you please advise?
Is there a reason that the target part C6652 doesn't work at the frequency so we should set the fCPU >=500MHz and use the power sleep controller according to [sprugv4c.pdf] ?

Or, fCPU=200MHz is good for the the part itself and it is possible to estimate the power dissipation?
