Hi Vivek, Please take a look at the MSP430 Hardware Tool's User's Guide for how to connect the FET430UIF to the device. For the F525x devices specifically, you need to follow the voltage requirements for the DVCC and DVIO rails. You can look at the device datasheet for more specifics, but the DVCC rail should be between 1.8V and 3.6V, while DVIO should be between 1.62V and 1.98V. During voltage ramp up, DVCC should never exceed DVIO until DVIO is fully ramped (DVIO should ramp up before DVCC). The reverse is true when ramping down the voltage rails (DVCC should ramp down before DVIO). This is explained in further detail in the device datasheet. Mike
