MSP430F5152: Search for MSP430 HW Design Guide Line

Part Number: MSP430F5152

hi,

my customer's project using MSP430F5152 be the subsystem, they need extremally low power consumption,

their FW using the interrupt event to awake MSP430 from LPM, and most of time, the MSP430 is in LPM mode.

but they found while in LPM3, their power consumption still have 2xx uA, that's too much more than the definiation in datasheet.

but they can sure the SMCLK is turn off by observing the SMCLK output.

so they start to aim the HW design, is there any document about the HW design guide line of MSP430?

Thank you.
