MSP430FR6043: Precise frequency measurement

Part Number: MSP430FR6043

Hello there,

I found MSP430FR604x which seem as very good candidates for precise frequency measurement rather than regular MCUs which are slow (nanosecond resolution). I would like to hear your opinion to this measurement requirements.

I need to measure frequency ranging 1-2 MHz of a square signal with averaging over the period of 50 usec.

time measurement resolution: <1ns

period of one measurement: 50 usec

I need to measure frequency from number of edges of input square wave signal during this period (50 usec).

I would use MSP430FR604x as described: High-precision time measurement resolution of ​<5ps

Q1: Can MSP430FR604x be used for such measurements?

Q2: Is there any working example for similar pulse signal measurements?

Q3: How does MSP430FR604x measurement method works?

Thank you for any help.

Best regards,

Michael
