Anyone tried looking for a 28-pin DIP part recently? You can't.

You certainly can't select your package type and even if you set 'pins' to 28 it shows no devices. You have to know that those parts are also available as 32-pin SMT parts and set the slider to 32 pins and then look at the datasheets to see if they are available as DIP.

Plus, some of the PDF links to the datasheets don't work.

Grrrrrr. They don't make it easy do they?

Now, don't be harsh. Some kiddie, who wears his cap backwards, knows how to program in Java, refers to everyone as "dude" and calls for attention with "yo!", has put a lot of effort into Atmels web pages and content management system. Appreciate his efforts, however decoupled from reality they are!

What does it matter that it is harder to use than ever and, as you've seen, is totally wrong sometimes? A middle manager, who owned the project and the budget, has seen the result and was happy. Perhaps he could even show it briefly to senior management, who thought it looked even flashier and thus where content and will grant new budget the next time the middle manager has two brain cells actually meet and they form a another bad idea?

I can't even find an up-to-date PDF version of the Product Selector Guide (latest I can find is Winter 2008) or the AVR Quick Reference Guide (latest appears to be Feb 2009).

It's enough to drive a man to Microchip.

I downloaded the spreadsheet or excel version which is just a csv file. I put it into a spreadsheet, then I can do all the good stuff that the moronic on-line selector does not do. As I recall, the button to do that is at the top of the selector page.

I also wrote a desktop app that would go through the csv file and find all lines with a user specified string, such as PDIP28, and make a new csv file from that. Anyone is welcome to it. Versions run on Mac, Win, and Linux. This app also works on Microchip selector downloads which are also csv files.

Hi Jim,

I'd seen the download as CSV option but, given that the package options are shown on the screen, I didn't bother with it. But lo, the downloaded file does contain package options.

And I've discovered package option can be made visible on-screen with the 'show-hide parameters' option. Woohoo!

But the Pins slider function is still borked.

You've invented grep! :D The prior art goes back to 1973, though. http://en.wikipedia.org/wiki/Grep http://gnuwin32.sourceforge.net/...

No, I did not re-invent grep.

I simply constructed an app with a convenient GUI that looks for lines with the specified string and writes those to a specified output file, after copying the header line. No grep in it and anyone can use it, without any grep knowledge.

Another problem with the selector is the lack of some significant information...I was recently looking for devices, including a 16 bit timer....the data only indicated whether 1 or 2 timers were available, not their width.

In the past I needed to determine which devices included the internal PLL to speed up PWM generation. A manual search was the only way to find out.

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!
