power consumption in sleep mode

[xuzhao09026]

Hey NXP,

We are trying to estimate the days of use when the device is in sleep mode. We don't want it to be in ship mode, ie no power supply at all, because we want a timely system reboot. Therefore, SRAM should be powered on. 

1. From the datasheet, in sleep mode, IVDDCORE = 3mA (12MHz, 0.7V). Can it be further reduced based on above condition? Or this is not the correct number I am looking for?

2. What are the other rails that needs to be powered? I understand that VDD_AO1V8 is necessary. Can you show me where the consumption numbers as well in datasheet?

Thanks

Zhao

Hi Zhao,

I recommend you to check this application note. Here you will see typical power consumption values with our EVK and how you can use this with our SDK example.

Best regards,

Please let me know how to calculate the overall power in this condition thanks
