Welcome @mhubert, to the community!
No, despite the similarities in the naming the ISM330DLC is not a functional replacement of the discontinued LSM330DLC.
To your questions:
- Is the ISM330DLC a functional replacement? similar
- Will our software team have to make changes to our software if we swap from the LSM330DLC to the ISM330DLC? yes, plus schematic changes
- Is there a migration guide for making this change? no
- Is there a different STMicro part that would be a more suitable replacement for the LSM330DLC? no
The ISM330DLC e.g. provides:
- much smaller package
- lower accelerometer noise
- two more gyro ranges
- better zero-g offset
- far better angular zero rate level
- far better drift on zero-g (mg/K) and zero-rate (dps/K)
- far better sensitivity drift over temp
- far better gyro sensitivity drift over temp
- better accelerometer ODR, far better gyro ODR
- improved power consumption
Hope that helps?
Good luck!
