Flash Memory AT25DF021A-UUNHR-T

During the design phase in which I find myself, I cannot find anywhere the footprint of the relevant component as mentioned above. I notice that on Page 8 of that datasheet, I find that the TOP VIEW is strangely different from the TOP VIEW on Page 57. I kindly ask if anyone can explain to me about this and which part of the two pages I should take into consideration. Thank you for your attention.

  • Hello,

    It sounds like you're dealing with a bit of a datasheet dilemma. When you encounter discrepancies in the TOP VIEW of a component footprint on different pages of a datasheet, it can be quite confusing. Here are a few steps you can take to resolve this issue:

    Check for Revisions: Sometimes, datasheets are updated, and different pages might reflect different revisions of the component. Look for any revision notes or version numbers on the datasheet.

    Compare Dimensions: Carefully compare the dimensions and pin configurations on both pages. Ensure that the measurements match the component you have.

    Manufacturer's Website: Visit the manufacturer's website to see if there are any updated datasheets or additional documentation that might clarify the discrepancy.
