MTBF eMMC (H26M52208FPR)

Hi,

We see that the MTBF for the eMMC mounted on the Apalis iMX8 processor has a fairly low MTBF. We are looking for the maximum amount of read/write actions that you can perform on this component.

Could anyone provide us with this information?

Kind regards,

Asterix

Hello Asterix,

you can read about the read and write cycles in the vendor eMMC datasheet. But over the lifespan of the SOM product the eMMC on the SOMs will change. This is normal and a process that you will be informed as a customer via our PCNs.
The best way here is to use the typical Embedded recommendations.

So to optimise the write cycles, and best use a different memory for dataloging.

Here are some interesting links about memory lifetime optimization.

Hi Matthias,

Thanks for the elaborate answer. As a follow up we noticed that the read and write cycles cannot be found in the vendor datasheet. We have asked this question directly to SK hynix, but they only provide support for purchasing customers. Could you please provide this value, or send the datasheet on which this value is presented ?

Kind regards,

Asterix

Hello Asterix,

which SOM version you are exactly talking about ?

Best regards,

Matthias

Hi Matthias,

In this case we are looking for the data on the H26M52208FPR mounted on the apalis iMX8QM 4GB IT V1.1C

Kind regards,

Asterix

So to our knowledge we have 00471102 Apalis iMX8QM 4GB IT V1.1C has MTFC16GAPALBH-IT on the module. Where did you get the info. maybe we have somewhere a documentation issue

Best Regards,

Matthias

The components are derived from pictures of both sides of the Apalis module, as well as from information given in the block diagram on page 11 (Architecture Overview) of the data sheet.

Will the “ MTFC16GAPALBH-IT” chip be used for future products, or will this be replaced in the near future (due to end-of-life of this component) ?

Hi,

We were still wondering if this chip will be used in future products since it is end-of-life.

Kind regards,

Asterix

Hi @Asterix !

About the chip used, you can check the revision history from Apalis iMX8 page.

You will see that from V1.1A on, the chip is really the MTFC16GAPALBH-IT

Also, from the datasheet, I could not find the information that you have.

And, as Matthias said, we can not assure you that this chip will be used for future releases because it can reach End Of Life (EOL). Then it will be replaced and the customers will receive the official Product Change Notification (PCN).

Generally, eMMC changes don’t affect the customers, however, it depends on a case-to-case basis.

Best regards,
