FXOS8700CQR1 IC marking

felicita · ‎02-21-2017

Hi all,

We designed our sensor board with KL46 and FXOS8700CQR1(Acc+Mag) and FXAS21002CQR1(Gyro). We got the boards working but with little accuracy issues.

We have again designed our sensor board with KL17 and FXOS8700CQR1(Acc+Mag) and FXAS21002CQR1(Gyro) following all PCB guidelines as recommended.

The observed issue is as follows:

Unfortunately, in our new boards (10 nos), magnetometer is not getting calibrated.

The new boards were assembled with magnetometer with IC (bought very recently) marking

8700

ENA

The same boards started working when the magnetometer was replaced with older stock (about an year old) with IC marking

8700

Does the marking on IC mean any version change?

It will be greatly helpful if someone can assist us in solving this issue.

Thank you!

Regards,

Felicita Mercy D.

Hello Felicita,

I assume the difference that you mentioned is in regard with the Errata for FXOS8700.
