SPRABJ8B September 2022 – November 2023 AM2631 , AM2631-Q1 , AM2632 , AM2632-Q1 , AM2634 , AM2634-Q1 , AM263P4 , AM263P4-Q1
This section outlines the latest estimates of the AM263x and AM263Px power consumption on a per device power net basis. These values may change as more power modeling and characterization is performed. This data can be used to scale peak DC-DC conversion power margin, perform IR drop analysis of the PCB layout, and help with thermal loading analysis.
These estimates are based on initial power simulations of the device when operating at 150°C junction temperature. For the latest characterized, peak power numbers, see the AM263x Sitara™ Microcontroller Data Sheet or AM263Px Sitara™ Microcontroller Data Sheet.
Also, a use-case based power estimation tool (PET) is provided for both the AM263x and AM263Px MCUs. These tools can help further bound the peak power based on specific core and peripheral utilization duty-cycle.
