AWR2243: Delta file compare with AWR2243 and AWR1243 DFP

Part Number: AWR2243
Other Parts Discussed in Thread: AWR1243

Hi,

My customer is working on AWR2243 cascaded board and found some register setting value is not same as AWR2243 and AWR1243 and there are also new Radar Messages/sub-blocks supported on AWR2243. As you may know processor sdk for radar v3.8 only supports AWR1243, customer would like to know the difference of AWR2243 and AWR1243 on RF message side to modify the current sdk.

Would you pls help to share a delta file compare the difference with AWR2243 and AWR1243 DFP?

Below are one example of difference.

Jitendra,

Thanks for your feedback.

The release note only gives a brief of the difference, but not detail. For example, I can't find the change on RX gain in the release note. I only found below info.

3.1.1 New Features (DFP 2.0.3 - Compared to DFP 1.2/AWR1243)

 AWR2243 is TIs second generation 77GHz RF CMOS Radar, features supported in this firmware release are:
o This release is derived from AWR1243 DFP1.2 release baseline and backward compatible to AWR1243 DFP 1.2 supported APIs.
o Synthesizer RF frequency supported 76 – 81GHz
 VCO1: 76 – 78GHz
 VCO2: 76 – 81GHz
o Supports 20MHz IF bandwidth
o Supports 266MHz/us max slope
o Supports New programmable filter (not characterized in this engineering release)
o 20GHz LO cascade configuration improvements
 Refer mmWave-Radar-Interface-Control.pdf (ICD) for more information on AWR2243 ES1.0 API details.

Would you pls kindly provide a detail difference document/table?

Hello Chris,

Let me check this internally if any existing info or table is available for device difference.

Hello Chris,

Could you look at appendices of ICD from DFP for AWR2243 API changes

https://software-dl.ti.com/ra-processors/esd/MMWAVE-DFP-2G/latest/exports/mmWave-Radar-Interface-Control.pdf

At IC level there is a comparison table in the Datasheet.

Jitendra,

Thanks to point me to the ICD appendices. It has a lot of update info.

But for existing API update, the info is not so detail. For example, it only says there is update to reserved fields in AWR_PROFILE_CONF_SET_SB, but it doesn't provide which parameter is updated. Customer needs to check parameters one by one and it will take time. Do we have more detail info on this?

Below is copied from AWR2243 ICD appendices.

The following are the updates to existing APIs in ’reserved’ fields, backward compatibility is not
impacted due to these changes.

11. Updates to AWR_PROFILE_CONF_SET_SB

Hello Chris,

I'm afraid that there is no further documentation available apart from what I have already provided.

I would request you to form that difference list to assist the customer.
