MSP432P401R: MSP432P401R:

Komathi Suppiah
Prodigy 30 points

Part Number: MSP432P401R

  1. Units failed at Functional Test due to voltage failure, no voltage output at VCCINT.

  2. Resistance measurement found VCCINT_FAULT signal was short to GND, measure 1.4ohm & 2.7ohm (for this 2 failing component). Good board measured 22Kohm

  3. Upon isolation found that U19 (MSP432P401RIPZR) causes the shorted.

  4. Measurement on component itself, found that pin 72 & 88 is shorted (1.4ohm & 2.7ohm). Good component measured 5Mohm.

Since failure occurred on NPI stage, requested to send this component for FA.

Failure Rate : 2/320(0.6%), DC =1723,

CPN:XILG-30-00017
