Part Number: MSP430FR2476

Hi expert,

My customer is wondering if msp430fr2476 only support 32.768kHz crystal or not. Can they use higher frequency crystal, such as 3.6864M? If not, why? thanks.

Regards,

Yangbo

  • Hi Yangbo

    You can't input a 3.6864MHz high frequency crystal into the XT1. You can use the 32.768khz crystal and use the DCO to generate a 3.68MHz frequency. We also have the test data at 16MHz that can guarantee the accuracy about ±0.5%
