SK-AM62A-LP: How to reduce the power consumption of the SOC to minimum level (less than 10mW)

Part Number: SK-AM62A-LP

Tool/software:

Hi TI team,

On the application note "AM62x Power Consumption“, the minimum power compsumption of soc on deep sleep mode is about 14.62mW. But it is still much bigger than that of other low power Cortex-A5/A53 MCU. Is there any method to reduce the power consumption to less than 10mW or 5mW? For example, disable all the internal functional blocks except WAKEUP block, soc work on RTC clock, and etc.

Best regards,

Wells

    Hi Wells,

    Lets breakdown the total power consumption further:

    SoC_DVDD1V8, SoC_DVDD3V3, & VDDA_CORE power is system dependent because they are I/O rails. This means whatever external devices the custom board design has connected to the processor will influence the power consumption of these rails. The data from the application note is for a TI EVM which is designed to enable as many peripherals as possible which increases the power consumption.

    VDD_CORE, VDDR_CORE, VDD_LPDDR4 power is SoC dependent rails. This means these measurements should be consistent between a TI EVM and a custom board design. The Core power will always be around ~5mW.

    Add both of these parts together results in the total power consumption.


    Best Regards,

    Hi Anshu,

    I see. Thank you!
