There is no such thing as PMS15A

freepdk opened this issue Β· comments

I have some PMS15A and when you read them out you can see that infact they are PMS150C (same hardware ID, amount of program memory is same, ...)

PMS15A is just a marketing name of PMS150C. Inside the IC is the exact same silicon. Not a single difference.

Only the PADAUK IDE is limiting the amount of code you can use in case you choose PMS15A. If you choose PMS150C then you can use the complete code memory (1K). Also original PADAUK WRITER happily writes the PMS150C code to a "PMS15A"... and of course, everything is working.

So you want to remove the device? However, if it actually is on the market, people will ask for it, regardless whether its the same as another type or not.

Btw, I also had this thought when I first saw the device. Since they don't even have identifying information on their packages, they could just relabel their reels.

We could have a 'notes' section at the top of the 'detail' page for the PMS15A explaining what @freepdk mentioned.
We could also modify the table for the PMS15A to just show a similar note instead of all the normal columns... or put an asterisk by the name with a note below the table.

Are we sure that Padauk won't introduce actual changes for the PMS15A in the future, or start shipping IC with potentially bad OTP memory in the upper half?

The notes section is a good idea. This could also be used to add information about other topics.

I also would do it like the data sheet and add is as a variant/ marketing name of the PMS150C in a "notes" section.

I added a note in #31. Let me know what you think. Preview: https://deploy-preview-31--free-pdk-preview.netlify.app/

The note is good, but it destroys your beautiful table.

How about showing ROM size as:
0.5 KW
(1 KW*)

And when you hover or click on the (1KW) then popup / tool tip shows the note ?

I also would place the row next to PMS150C (above or below).

done!

Hmm, I tend to like the current design with the extra table row. I feel like using a tooltip or popup is unnecessarily complicated (and would require JavaScript if we want to still have a clickable link to the "Source")

Alright, take another look at the preview πŸ‘

Looks great :-)
