MK20 power consumption

[sreeramadhanala]

Dear sir,

I am beginner for  Kinetis  Controllers.

I am using MK20dx128vlh5 for my application.

But , I  am not understand supply current of "MK20dx128vlh5"  !

I saw two variants in datasheet as shown in below

1.

2.

But practically i observed  "2" condition.(I observed "18.9" mA).

Please clarify , "1" condition requirements ? & Which one is real supply current ?

Thank you.

Hi Dhanalakshmi,

There are two Application Note about the power consumption of Kinetis MCU.
AN4470 Using Low Power modes on Kinetis family
AN4503 Power Management for Kinetis MCUs When and how to use Kinetis low-power modes

The current of MCU is depend on how you use the MCU.
"1" 155 mA is the maximum current of MCU.
There are several low power modes for Kinetis MCU, "2" Run mode is one of them.

Best Regards,

Robin
