MSP430FR6043: Max measurement frequency

Part Number: MSP430FR6043
Other Parts Discussed in Thread: MSP430FR6047

Hello,

Is it possible to make time of flight differential measurements at more than 300 Hz and do we know the maximum frequency?

Thanks, 

Pierre Gambier

    Hi Pierre Gambier

    Based on MSP430FR6043 data sheet,

    for water flow measuremen,  ±12.5-ps differential time of flight (dToF) accuracy at low to high flow rates and across operating temperature.

    for gas flow measurement. ±250-ps differential time of flight (dToF) accuracy at low to high flow rates and across operating temperature.

    Thanks!

    You may be interested to see the FAQ on Ultrasonic Sensing (SLAA837), question 10: "What is the fastest measurement rate that the MSP430FR6047 or MSP430FR6043 can update the flow rate?"

    To do what you want would take firmware work on your side.
