IWR1642BOOST: Is my EVM ES 1.0 or ES 2.0?

LAXMI KANT TIWARI

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hi,

I have silicon number written as follows but now sure which version is it.

IWR1642
QG

82ZCSN9
502AC    ABL     G1

Can you please anyone from TI confirm it, which version is this?

Laxmi,

Please refer to the "Device Nomenclature" of the IWR1642 datasheet that can be found here to determine which silicon revision you have:
www.ti.com/.../iwr1642.pdf

Also cross reference with the errata. Also this question has been addressed several times on this forum. You can find that answer on this forum.

You will need to look on the actual packaging to determine this information.

Regards,
Kyle

Hey Kyle,

Nomenclature is kind of confusing in the datasheet. If you visit page number 76, you will notice that nomenclature is not matching as said in the Datasheet. There is nothing mentioned about following

82ZCSN9
502AC

Do you understand what I am trying to say?

I had the same question and problem. Short version: I think that you and I both have a ES2.0 device, however, I am having difficulty proving this electronically (vs reading the IC nomenclature) because attempts to demos were unsuccessful. For more details regarding EVM version, see my posting here:

New evaluators might find my August 2018 forum questions to be helpful or interesting:

Thanks Raymond.

I would like to one more point here is that there is no IC available named IWR1642A. But I am not sure then how TI employees have been suggesting to look IWR1642A. I am still figuring it which board it is!!!

The takeaway is that an ES2.0 label applies not only to the board: it also applies to the version of the radar chip, which is also supported by TI's Akash Gondola:

If it [1642 radar chip] says 502 then it is ES1.0, and if it says 502A then it is ES2.0.

Laxmi,

You can verify that you have an ES 2.0 device by running the Out-of-Box demo from SDK 2.0.0.4 on your EVM successfully.

You can download the SDK here: www.ti.com/.../MMWAVE-SDK

You can use the demo visualizer here: dev.ti.com/.../

Kyle
