PAL16R4AM: PAL16R4A Full Power vs PAL16R4A-2 Half Power

PAL16R4A vs PAL16R4A-2

We were using the PAL16R4A-2 (half power part) in our design. We can no longer get it so we are switching to the 16R4A (full power). We are concerned that the Full Power device uses more power, but at the frequency and the burn file we are using we are measuring about the same current for both parts (half and full power). Can we assume that future Full Power parts will use the same amount of power that we are measuring now?

Thanks

Mike,

I am not certain on this, and will need to do a little research to see if I can find some details to help answer.

I will reply back with what I find.

Mike,

Can you provide me with the orderable device number for the a-2 half power device?

The original PAL we presently list on the BOM is pn: JM38510/50410BRX. for the Half Power device

The new PAL we are testing for addition to the BOM is pn: M38510/50404BRX for the Full Power Device

Mike,

I was able to confirm that the A-2 and the A versions used different die. I was not sure if devices were speed sorted for this.

Unfortunately, I was not able to locate any data on the implementation of the power savings for the A-2 devices as compared to the full power variants.

I would suspect that the material you are testing would be representative of the performance of the entire population of devices.

Hopefully this helps.
