MMA8452 replacement ?

[marcick]

I'm using since some years this sensor to detect vehicle movement and I'm working now on a new project.

Is it better I choose anther model more actual and (maybe) with better performances or is 8452 a good and "young" devices to continue working with ?

Thanks

Hi Marco,

MMA8452 is part of the Product Longevity program with assured supply for a minimum of 10 years after launch. The MMA8452 was launched on Feb-2010.

You can confirm this information in the product longevity program page: https://www.nxp.com/products/product-information/product-longevity:PRDCT_LONGEVITY_HM

This means that we guarantee the production of the part until 2020, after this time we do not have an estimate of years that this will be in production as per it is market driven.

In case you want a newer accelerometer similar to the MMA8452, you can check the MMA8652: https://www.nxp.com/docs/en/data-sheet/MMA8652FC.pdf

Have a great day,
Jose

Mouser and Digikey now have the MMA8652 as end-of-life / last time buy. Can you recommend a new one?

It's been strange to watch the entire ecosystem built around the MMA8452 collapse in realtime on eBay, Amazon, etc. as what used to be a ubiquitous chip has its days numbered.

Thank you very much Jose,

I’ll have a look to 8652. Do you think it’s my best choice ?

I need to detect when a car starts moving with the maximum sensitivity (would be great to detect also the door opening I would say) but without false alarms.

With my actual 8452, if the car start slowly and the ground is flat and regular, sometimes I intercept the movement with a delay of 30 sec or more that is too much (I have opened another thread to ask help and see if I can use a different configuration).

Anyway, for the future sensor, I would need the best for this kind of application.

Thanks

Marco

Hi Marco,

For high sensitivity requirement applications, I would recommend you the MMA8451 or the FXLS8471 which have up to 14-bit of resolution (vs the 12-bit of resolution of the MMA8452 or the MMA8652).

MMA8451 datasheet: https://www.nxp.com/docs/en/data-sheet/MMA8451Q.pdf

FXLS8471 datasheet: https://www.nxp.com/docs/en/data-sheet/FXLS8471Q.pdf

The MMA8451 is listed as End of Life / Last Time Buy on Mouser and Digikey. Is there a replacement?

[marcick]

Thank you. I will move to FXLS8471, it's almost pin-to-pin and (hope) more longeve

[reyes · Accepted solution]

Hi Marco,

FXLS8471 is not part of the product longevity program, however, it is a much newer device than the MMA8451, so yes, I would also expect it to be a more longeve device.

Have a great day,
Jose

The FXLS8471 is marked end-of-life/last-time-buy by Mouser and Digikey. Hate to be a broken record but what's going on? Is there some new version?
