Hi Stefan,

Assuming the application will be for ultrasonic flow metering, we recommend the MSP430FR6047 to replace the TDC-GP22.

The TDC1000 is no longer recommended for ultrasonic flow metering due to its inferior accuracy and thresholding technique for flow metering. The TDC1000 has been recommended exclusively for liquid level sensing and concentration measurements. You can read more about the differences and where we recommend specific ultrasonic devices on the PGA460 E2E FAQ here: https://e2e.ti.com/support/sensors/f/1023/t/748143
