MSP430FR2422: how to calibrate DCO by some GUI without external crystal oscillator?

Part Number: MSP430FR2422
Other Parts Discussed in Thread: MSP430G2553,

dear all,

i used MSP430G2553 in my last platform design and recently i want to change MCU by MSP430FR2422. but i meet a tough question is that i need to calibrate DCO by some GUI because the design without external crystal oscillator. do you have some GUI or software to realize this requirement? 

thanks a lot. 

  • Hi Damien,

    As talked, the customer required the DCO frequency runs in +/-2%. Please be noted that FR2422 FLL could match this requirement. You should take care of the test condition(3V VCC) as well as the clock configuration(16MHz)

    Also, you could take below code example(running on FR2311) as the software trim function.
