I used msp430F4152 in our project

we have external 32Khz crystal and Lpm3 mode is enabled.

only crystal and 47K resisior and 2.2nf capacitor is connected to the rst pin

still current 63uAmp.

in datasheet LPM3 current is 0.9uAmp

Hi Anushka,

Is the crystal actually connected to the RST pin? I hope not.
It needs to be connected to the XIN/XOUT pins.

Have you programmed a lpm3 code to the device?
Can you try the code example from web for verification?
Can you maybe post a picture of your schematic?

Best regards
Lukas
