Other Parts Discussed in Thread: AM5718, AM5726
Question from customer:
Currently we're operating the AM57xx SoC in OPP_NOM during what we refer to as Energy Star mode for the machine because the task of actually putting the AM57xx into suspend (DRAM self refresh) was considered to require significant firmware effort which would affect our engineering schedule.
Because of this, we're currently trying to understand how we can further reduce the power consumption of AM5726 while in OPP_NOM as our system power consumption is currently higher than desired when the machine is idle. Our AM5718 based systems have no problem getting to a low enough power consumption level to meet our product needs.
Our most recent question is relating to being able to run the AM572x MPU subsystem at clock frequencies less than 1GHz (ie: maybe at 500 MHz?) so as to reduce power consumption when in OPP_NOM. Is this possible?
It would also be helpful to us if we could understand what the distribution of minimum voltages and actual measured power consumption are for idle AM572x SoC when in OPP_NOM. The recently published white papers about power consumption seem to not provide any statistical data, they only show one snapshot of a single sample, which isn't that useful to us.
