OMAP-L138: End Of Life date?

Jorge,
Thanks for considering using our device.

OMAPL138 and C6747 are part of a successful family of devices and we are selling both to a wide range of customers and applications.

Product longevity is important to TI and its customers. To meet customer needs we employ strategies such as inventory management and multiple sourcing tactics to address continuity.

Here is an external link to TI's GQC (General Quality Guidelines) that references TI's EOL policy (Section 20): www.ti.com/.../getliterature.tsp

Now, If you are looking for a more powerful combination of Arm + DSP, you can take a look at AM570x family.

I hope this helps.

Hi Rogerio,
Thank you for your quick and helpful reply.
So, although the OMAPL138 and C6747 have been launched one decade ago, it should still be available for the 5 next years?
We will look at the AM570x family which seems interesting. What would be the advantage of using the C6747 instead of the AM570x for a new project?
This is for a microphone-array product, so the DSP has a key importance.
Thanks.
Best regards,
Jorge

Jorge,
TI takes seriously any EOL decision and our policy explain more in details. OMAPL138 and C6747 are used largely by our customers.
Regarding your 2nd question, C6747 has DSP only while AM570x has DSP plus Arm, what allows you to use the Arm as application processor while DSP handle other tasks.
But if you are looking for microphone array, I would recommend to check this reference design before anything: www.ti.com/.../TIDA-01454
I hope this helps.

Thanks Rogerio.
It seems that we can reuse the code developed for the C6747 on the AM570x, right? this would be great.
Do you see any reason to use the OMAP-L138 instead of the newer AM570x?
What kind of libraries for the DSPs are available for microphone-array Beam Forming, Noise Reduction, Acoustic Echo Cancellation and Automatic Gain Control?
Thanks.
Best regards,
Jorge

Jorge,
C6747 has a C67 DSP and AM570x has C66 DSP, and C66 runs the same code.
OMAL138 would have lower cost, smaller package, lower power consumption all because of the features it has, while AM570x is more multimedia device. The sales responsible for your account would be in a better position to give you pricing idea for the volume you have in mind.
Now regarding libraries, there are details here: www.ti.com/.../telecomlib

Jorge,

Just a little bit more information to your questions:

- Differences among C674x DSP and AM570x:
IN addition to performance differences, you will find the C674x DSPs are lower power consumption than AM570x. A good estimate for C674x is ~1W (application dependent of course). You will find AM570x to be at least twice that. Price ranges are a bit different also, as you might expect given the performance and integration of the AM570x.

Microphone Array processing:
We have an example of multi-microphone array processing done on the C6747 DSP. Please see this TI Design: www.ti.com/.../tidep-0099. You may find it very useful as a starting point.

Good luck!

Thank you John.

It seems that the AM570x was launched around 2015, while OMAP L-138 was launched around 2009, right?

So AM570x seems to be a much newer product.

But regarding DSP, the AM570x uses DSP c66x which does not seem much newer than c6747.

Besides price and performance aspects, would AM570x be the right choice for a new project?

Thank you.

Best regards,

Jorge

Jorge,
let me jump here.
AM570x was released to production this year.
And C66 combines the benefits of Floating Point with Fixed Point, being compatible with C67x as well as C64x families of DSP.
After analyzing the features, you can decide which one is a better fit for your design.
All these devices are in full production.

Thank you Rogerio.

Best regards,

Jorge
