Unclear datasheet AT25XV041B
Posted byKonstantinS32 points 2 repliesDear Support,
I would be very happy if you could answer the following 3 questions as we would like to start with a 0-series production.
1) Is theAT25XV041Bsoon going to be marked end of life / not recommended for future development?
2) On page 46, theAT25XV041Bdata sheet lists the dimensions of the package type that dont fit the technical drawings.
Which dimensions are the correct ones to look at? The Package Type table or the technical drawings?
3) What does the order code AT25XV041B-UUVHR-T stand for?
The UUV seems clear at first, but what would the HR stand for?
I found this in a mouser offer:https://eu.mouser.com/ProductDetail/Adesto-Technologies/AT25XV041B-UUVHR-T?qs=AX3SRYwdf7H0g3d80jh3uA%3D%3D
If you have any questions feel free to call me directly.
Best regards,
Konstantin

We have no plans to EoL the AT25XV041B-UUV-T part but I can find no mention of this part with the High Temp (HR) suffix.
The 3x2x3 refers to the ball pattern and NOT to the physical dimensions. I will ask our marketing team to correct this. The correct dimensions are shown in the drawing a few pages below.
HR => High Temp
Just as a note - If you do not need to operate at 4.4V and do not need High Temp, I would suggest you qualify the AT25XE041D parts at the same time. I understand that you may only be looking at this part due to shortages else where. Note also that we use the same silicon for the High Voltage and the High Temp parts but run them down different test paths. So if you are looking to find replacement parts for the standard AT25XE041B the the XE041B-UUVHR-T (high temp 3.6V) or the XV041B-UUV-T (4.4V) will both work without modification to HW or SW.
