Hi Expert,
in datasheet of tms320dm6437Q5 , internal core voltage can be either 1.2V or 1.05V, I made use of spreadsheet(see it in attachment) downloaded from TI website to compare the power consumption, it's interesting that
when the DSP frequency is 400MHZ,
the power consumption for CVDD=1.2V: 925mW
the power consumption for CVDD=1.05V: 653mW
so the gap of two configurations is very big: 925mW-653mW= 272 mW,
are you sure the gap is reasonable?
consider lower power consumption, now tms320dm6437Q5 is supplied by 1.2V, if it's supplied by 1.05V, the only change is to change the CVDD from 1.2V to 1.05V, right? is there other changes to be done?
by the way, is TMS320DM6437ZWTQ5 pin to pin for TMS320DM6437ZWTQ6? if iTMS320DM6437ZWTQ6 is replaced by TMS320DM6437ZWTQ5, is there any changes to be done?
thanks for your detail information in advance.6437Q.rar
