C5535 DVDDIO power suply

sam lai

Dear All :

We're reducing power consumption issue.

If we want to decreasing the DVDDIO voltage from 3.3V to 1.8V, what should we do??

Just decreasing the DVDDIO voltage directly??

Hi,

It's purely hardware and there is no software controls over 3.3 V to 1.8 V change.

You cannot dynamically changing DVDDIO. DVDDIO needs to be set at power up.

Dear Steve :

Thanks for your reply.

We don't want to change it dynamically.

Actually, we want to change the reference design of C5535 ezdsp.

We'll supply 1.8 voltage to DVDDIO on power up.

Does the software/hardware require some changes for reducing the DVDDIO ??
