Hi Mark,
please see below for answers to your questions from a Product Marketing Manager.
DESCRIPTION
1. The MMA8451QT is 14 bit resolution and has a 32 sample fifo. I see the FXLS8962 has a 32 sample fifo so that is good but only 12 bit resolution. Is there, or will there be, a replacement with 14 bit resolution?
a. NXP does have a product with 14-bit resolution on the roadmap that is currently target for launch in 2024. The product is still in the early product definition stage, and resources on this product will only be assigned after the launch of FXLS8964/74.
2. Will there be a drop in replacement for the MMA8451QT? I am assuming the answer is "No" since I was not stated in the power point.
b. As stated above, NXP does plan to launch such a replacement for MMA8451 (expectation is that the part will be pin compatible to MMA8451 but not necessarily SW compatible)
3. Is there an app note to show how to migrate from the MMA8451QT to the FXLS8962 and/or the FXLS8964/74? That would be handy for those needing to re-spin current designs. And if a board needs to be modified for other reasons it would be nice to roll in this change and not have to re-qualify again.
c. No such App Note is currently planned, but it will be considered as part of the FXLS8964/74 launch efforts
With Best Regards,
Jozef
