Hey Forum,
I'm thinking of using an ATtiny26 in my designs. The
Wiki says:
Clocking the AVR from the RC oscillator with auto-calibration
V-USB requires a precise clock because [...]
[...]
[...]AVRs known to have this option are the ATTiny25, ATTiny45, ATTiny85, ATTiny26 (not recommended for new designs), ATtiny261, ATtiny461, ATtiny861.
What is that "not recommended for new designs" supposed to mean? I can't make sense of that. If you have a clarification, please enlighten me.
Thanks alot,
-Christoph

Normally that means that the chip has reached end-of-life and its production is about to be shut down. Seems that Atmel changed their mind tho, the last two entries from the ATTiny26 manuals revision history:
Rev. 1477K-08/10 Added tape and reel part numbers in “Ordering Information” on page 171. Removed text “Not recommended for new design” from cover page. Updated last page.
Rev. 1477J-06/07 1. “Not recommended for new design”
