MSP430FR6047: Need help to designing the schematic.

Part Number: MSP430FR6047
Other Parts Discussed in Thread: MSP430FR6043,

Dear TI, 

We have observed the design files from both MSP430FR6043 and MSP430FR6047, it is found that in FR6043 you have used L1,L2,L3 of 600E between MCU_VCC and AVCC1,DVCC1,DVCC3, respectively. Where as if we observe in FR6047 there is no inductor connected between the MCU_VCC and their grounds, respectively. Need Help ASAP. 

Thanks in advance.

    Hi, 

    For the FR6047 there is no need to add an inductor between VCC and GND. However, for the FR6043 in a gas meter application, the excitation current on the transducer is larger than in water meter application. So an inductor can lower the voltage jitter on the VCC 

    Best regards,

    Cash Hao
