Hello abialevich1,
I hope all is great with you. Thank you for using the NXP communities.
The FXLS8974CF targets industrial, medical and IoT market while the FXLS8967AF is recommended for general purpose automotive use cases.
Therefore, the FXLS8967 are specifically PPAPed for automotive application, while the FXLS8974 is not.
For the FXLS8974, you may notice FXLS8974 spec typical values are all the same as FXLS8967, with differences that FXLS8967 spec puts a lot more restrictions with min/max limits for key specs like sensitivity and offset, power consumptions… over the operating temperature range of -40deg to 105deg for automotive environment, while FXLS8974 datasheet only specifies typical value at room temperature for industry use over range of -40deg to 105deg. Refer to screen shots below.
Refer to below picture for differences on software side, all 2 variants have the same register map expect the FXLS8974 has a minor change on REF_UPDM bits in SDCD block which makes it better fit for slow motion detection in IoT.
I hope this information helps.
Regards,
David
