Talk:ATtiny microcontroller comparison chart

Contested deletion
This article should not be speedy deleted as lacking sufficient context to identify its subject, because... (your reason here) --Krikkit1 (talk) 13:32, 2 August 2012 (UTC)

Because it is a table that probably nobody wants to have in the main article (Atmel_AVR) on it itself. The attiny doesn't justify a page on it's own, it's already covered well by the general Atmel_AVR page. I think the comparison chart is very valuable tool, as this information is otherwise scattered.

Copyright
This looks very much as though it is copied from the Atmel site, in which case it should not be posted here. In any case, it's not an encyclopaedic article. Peridon (talk) 14:11, 2 August 2012 (UTC)

Issues as stated above and elsewhere about this page
There is NO such table at the atmel site itself, even though you would expect that way. It seems once indeed there was such a table. The table is NOT copied, the information in the table is collected from the datasheets available at the site.

If I would rewrite this into an article about the attiny in general, would that count as a valuable encyclopaedic article? I don't think this table should be in the Atmel AVR article, it is already too long. Krikkit1 (talk) 17:06, 3 August 2012 (UTC)


 * You could at least explain what the thing is about. At the moment it's a bit, shall we say, specialised? I used to read data tables for transistors and ICs and other such with no problems, but to outsiders this sort of thing is gobbledygook. Wikipedia pages should explain what they are about before getting into the formulas, tables and other insider stuff I'll accept that there isn't a page at Atmel - I've not found one at least. Get some info at the top of the page to say what, who and possibly why. And add a ref or two that are independent of Atmel. Doesn't have to be in depth - just show that someone outside the factory has heard of them... Peridon (talk) 21:29, 3 August 2012 (UTC)


 * Okay, you have a point there. I will give it a shot very soon. Krikkit1 (talk) 19:31, 12 August 2012 (UTC)


 * Okay this way? Krikkit1 (talk) 13:27, 18 September 2012 (UTC)

Does ATtiny85 support SPI?
According to this table, it doesn't, but according to, it does. 95.143.93.93 (talk) 08:15, 6 September 2013 (UTC)
 * That page makes me raise my eyebrows... 5 output compare channels, 6 PWM channels? I can not construct a reasoning that would arrive at those numbers. Anyway, the SPI column on that page almost certainly refers to the USI unit the ATtiny85 has. I see that this article now lists both USI and SPI as if they were separare things, so I'm going to delete the SPI entry. It is the USI that supports SPI communication in this model.

PWM pins on ATtiny85?
It seems the information is not 100% ok - it looks like ATtiny85 has 3 PWM pins, although the 3rd one is not directly supported by Arduino IDE -  — Preceding unsigned comment added by 46.126.101.51 (talk) 21:04, 9 May 2016 (UTC)
 * Thanks for the heads up. Fixed. — Edgar.bonet (talk) 08:05, 10 May 2016 (UTC)

Number of Counters
As I'm working with the ATtiny85 right now, I know there is only a single 8 bit counter. There are, however, 2 compare registers that reference that single counter.

Now is the Counter column in the table supposed to be the number of counters, or comparators ? HiTechHiTouch (talk) 16:27, 23 February 2018 (UTC)

Table cleanup
Lots of great work before I showed up!

1) I reordered the rows in the table, by sorting against the left most part number. It's not a perfect fix, because multiple part numbers per row, but it's an attempt. Please insert missing parts in proper order.

2) I added a blank line between rows to make it visually easier to edit. This doesn't cause any problems with the WIKI engine, because I've done the same in the past with other large tables.  Please keep the blank lines.

3) I started cleaning up the package column. We should standardize on common terms to make it easier to compare parts, thus should put notes to clarify packages that might have multiple names.

4) I compressed the date field column by adding the "format=y" parameter to all "dts" templates. This will free up some horizontal space for a datasheet or webpage column on right side.

5) I added a webpage reference column on the right side. Pointing at the webpage instead of a PDF file, because there is more information available than a single datasheet.

6) I started adding Nowrap template around each package to prevent wrapping at the dash.

7) I changed the dash (missing features) to Red NO.

8) I removed date column, and move information into new 2nd table. The timeline table still needs to be finished... 2 unfinished groups very old chips (top line) and newer chips (bottom line).

9) I colorized the series buses: red mean doesn't exit, green means dedicated feature always exists, yellow means a multiple capability feature.

10) I added the 16-bit RTC timer to the timer column.

11) I swapped the location of 2 groups of columns: 1) "max clock", 2) "gpio pins" & "IC packages".

12) I'm done.

Help
Please help fix the remaining grey (gray) cells:
 * "PWM" column. 10 cells need fixed, all have timers, but I don't know how to create the "timers x waveform generators" format.
 * "GCC architecture ID" column. 1 cell needs fixed.

Thanks in advance! • Sbmeirow  •  Talk  • 07:56, 29 July 2018 (UTC)


 * Latest 2-series parts also use GCC architecture avrxmega3

GPIO Count
Some chips do not support input on all of the GPIO pins, thus the GPIO pin count is not very helpful. Might be worth adding max input pins, and max output pins. EdHayes3 (talk) 19:23, 1 October 2020 (UTC)

DAC
DAC data are missing. -- 2003:E4:A709:D047:10B0:55DE:5A07:2091 (talk) 20:15, 10 March 2021 (UTC)
