There may be another advantage to the AXM0F343... I think onsemi has a SDK which will generate code for the ARM processor to talk to the attached ax5043. I'm not 100% sure about that, but I thought one of the support people mentioned that back when I was working on the ax5043.

Thanks Eric.
It is a factor of three time the price of the AX4053.
The quantity would indicate it’s not been a big seller when compared to the last quantities for the AX4053.
Digi-Key has a supply but end-of-life is noted with a last time to buy date of 12/30/2022.
Last week I checked the stock and they had a few which is normal with the supply chain but no notice of end-of-life.
I went back yesterday to order and the quantity was zero with EOL noted and found the same conditions at Mouser.
Arrow and Newark have about 2000 together and I found a few at LSCS Electronics in China but have never done business with them.
Now or never time.

Good discussion thread............................let's keep it going.
*GOOD NEWS**:* JK just sent me a FUTURE Electronics 'Featured Product' advertisement (attached) that he just received this morning for an AXM0F343 -- (thanks John). This appears to be a low budget/low freq RF SoC in the spirit of Xilinx's high end chips. It is a 5mm x 7mm QFN40 chip with 0.5mm pin pitch that contains an AX5043 PLUS an ARM Cortex M0+ microcontroller..................neat! This may be attractive for FOX+/PacSat multichannel applications, as it would appear that "n" of these chips on an RF card could provide "n" independent comm channels. That is, if one channel were to fail, that "should" not affect ops on the others I would think................*However*,
*BAD NEWS*: If you read the long list of ONSEMI's discontinued EOL chips that I sent earlier, you'll see THIS chip is also on that list!
*NEVERTHELESS*: If we studied this chip more carefully and concluded it could be a viable RF SoC component candidate for GOLF, FOX+, PacSat, LTM, etc, it is available in the thousands from Digikey, Mouser and others for a little over $6 each, Qty 25 for the 64kB Flash; 8 kB RAM version, or ~$8 each for the 256kB Flash; 32kB RAM version.
It's still not clear why ONSEMI is going EOL on their AX5043 core chips.....................does anyone know?
