What are supply cuurrent requirments for the 2.5 Volt core and the 3.3 Volt I\O. I suppose the 3.3 Volt is dependent on I\O usage but what is the min with out and loading and sourcing. Thank you Vince Leslie
Are you asking about voltage ramping? If so, you just need to hold reset active low for 40ms after both 2.5V and 3.3V have reached their minimum operating levels. Check out the Timing section in the NET+50/20M manual. It should have what you’re looking for.
Thanks Sue, What I really need to know is required supply current to the core and the I\O, to calulate power supply requirements. Thanks Vince
It’s in the timings section of the 8833450A user manual under DC characteristics… expressed as power dissipation at a given voltage and SYSCLK… Regards Dave
