MKL03Z: Current consumption too high in VLLSx states

Hello,

 

I am employing VLLS3 and VLL0 in my system design for MCU sleeping with RAM available and without RAM respectively. I have the VCC line to the uC and routed it through a micro-ammeter. Following are the readings I get and I am afraid they are much higher than what is specified in the datasheet. My supply voltage is 2.7v and in VLLS3 state the LPTMR is running based on the LPO clock.

 

VLLS3 = 4.7uA
VLLS0 = 3.8uA

 

Please help me in reducing the current consumption. I will be willing to share the schematics in a personal message with NXP.

 

Thanks in advance,

Gaurav Banyal.
