Hi,
I plan to use ICM-20689 as drop in replacement for MPU6050 ( well, I know I have to change software for that).
But I have noticed one electrical issue - nCS pin of ICM-20689
I have the pin as "Not Connected" in MPU6050 (in my design).
Placing there ICM-20689 could cause mess if there is not at least weak pullup on the chip.
Unfortunately the ICM-20689 documentation does not say anything about it - is it omission or it is really "floating" input ?
The diagrams do not show it as requirement when showing i2c communcation mode, but can it be trusted ?
I would need new board revision to fix it - I would like to avoid it.
