Hello,
What is the lowest power consumption bench mark in standby mode of AM263Px Controller, when in Non-XIP OSPI flash.
Thanks.
Hi Sudhakar,
Standby mode in AM263Px is putting the cores into WFI (AM263x MCU+ SDK: WFI - Standby mode demo (ti.com)), and clock gating all the unused peripherals. When you say benchmark, could you please clarify what exactly you are looking for?
Thanks,
Sahana
Hi Sahana,
I was looking for what is the minimum possible power that AM263Px can consumption ?
Hi Sudhakar,
When all the 4 R5F cores are out of reset, released and put in WFI, all unused peripheral clocks and peripheral PLL is gated, the power consumption at room temperature (25C) is about ~600mW. This is the lowest possible power when your application is using all the 4 R5F cores. It can be further reduced if your application has unused memories which can be disabled. Please note that the power characterization is still ongoing and the Power Estimation Tool (AM263P PET) will be released on ti.com shortly, which will help you estimate power as per your use-case.
Thanks,
Sahana
Hi Suhana,
Is the above measurement taken with 400MHz CORECLK and 200MHz SYSCLK, if not could you please specify the clock frequency which was used ?
I assume the above measurements are taken with loading the program from Ospi flash in NonXIP mode, please correct me if I am wrong.

Hi Sahana,
600mW means
Micro input supply voltage is 1.2V
Micro current consumption is 0.5A
Is my understanding is correct ?
Also could you please share the source, to check in my setup !
Yes, the above measurement is with 400MHz CORECLK and 200MHz SYSCLK and loading the program from OSPI flash in non-XIP mode.

Hi Sudhakar,
It is about ~0.45A on 1.2V and about ~0.02A on the 1.8V and 3.3V rails.
You can refer to the application note https://www.ti.com/lit/an/sprad70/sprad70.pdf to obtain power measurement, which can be extended to AM263P as well. This will also be released as an SDK example shortly.

Sahana
