Hi,
I would like to have a comparison of power consumption of these 3 MCU (only the core consumption, ALL the peripheral disable).
For the F28335, in SPRS439L is indicated: The baseline Idd when the core is executing a dummy loop .. at 150Mhz.. : is 165 mA
For the F28069, in SPRS698E is indicated: The baseline Idd when the core is executing a dummy loop .. at 90Mhz.. : is 40 mA (72 mW Vdd:1.8V)
I guess we may suppose that : For the F28335 at 90Mhz.. : is around 100 mA (180 mW Vdd:1.8V)
So does it mean that the core power consumption of the F28335 is two times higher that one of the F28069 ?
However both have a: TMS320C28x CPU and same FPU unit.
Am I wrong ? Could you indicate to me if I am wrong ?
At last when I use the OMAPL137_PowerSpreadsheet_RevC.xls, and disable everything (ARM included) except the DSP and configure the Device Frequency to 90Mhz and % utilization (80%), the result is: 142 mW. That is lower than the F28335 but above F28069. But in this case it is not the same CPU core so we have also to take into account a ratio of performance. Do you have an approximation of this ratio?
Do you have some power consumption comparison between C600 and C2000 ?
Thanks for your answer
