Anyone have programming information on the 25? Is it just a smaller, slower ATtiny85? Tnx.
smaller flash, EEPROM, SRAM

The datasheet provides all the relevant information for programming and otherwise using the device!
Heh. Yes. 234 pages of everything I need on 6 legs of a DIP (vcc, gnd given). If only Cliff Notes did data sheets.
Since your question wasn't very specific, what did you expect? People to magically provide you with what you hadn't realized you were looking for but that happens to precisely match whatever it is you're trying to do...?
Yes. Why do you expect me to actually describe what I seek?
I don't.
Not physically.
Nope
Ok. I poked around the 234 pages. Looks to have less space. I was thinking it was slower, but thanks for the answer that it is not. I wish I could read datasheets better. Just so much extra info, I get lost.
The AVR chips were produced in series like ATtiny85, ATtiny45, ATtiny25. Typically the only difference between the products in a series is memory, while the CPU and peripheral specs are the same.
The idea is that the manufacturer of a consumer product would like to have the option to reduce their BOM cost in exchange for the loss of memory capacity that is going unused by their firmware. It can also be handy to have a chip with more memory to use for the initial development and debugging when your program might be bigger than the final production version.
For the maker/hobbyist/educational market, it probably is most sensible to just pay a little extra for the less limiting chip, but the challenge of fitting a project into the constraints of one of these chips can sometimes be fun.
And of course in this time of supply chain troubles we might find that some parts are simply not available or significantly more expensive due to scarcity.
It helps uf you know what you're looking for. So the question "is a tiny25 nice to toy around with" doesn't make much sense - it becomes different if you ask for instance "what are the adc capabilities of the tiny25 and does it have an adc watchdog?" Then all of a sudden it becomes a lot easier to navigate that stack of pages.
It's like everything to do with knowledge. It takes the skill to ask the right questions. This is the essence of about 95% of the threads on this forum...
Thank you.
