That new Atmel Tiny4

Started by Stefan Arentz December 17, 2009
I'm trying to get my hands on the new 6-pin SOT-23 Tiny controllers
that were recently announced. But I can't find them anywhere. This is
for hobby use so I just want a small bunch of them.

Has anyone been able to get them at all? I wonder if they have
actually been released.

Yo, what!?!? SOT-23-6 8-bit micros?? Where? I'll consider them even if they are from Atmel! I'm off to go look..... Jon

Hmm. Never mind. I forgot. I looked at that 4MB datasheet on Nov. 24th, this year. And wasn't able to find what I wanted. Jon

Super, but no Eeprom so limited use. good pwm etc,

Availability at Digikey (not that I buy them there, but it is an important indicator) and Mouser. ATTiny10 is qty 0's at Digikey, non-stock at Mouser. Reliable, programmable brown-out detect and POR, internal ring osc with 2-5% over temp, small eeprom, comparator, and bandgap -- adc as an option instead of the comparator, 5.5V down to maybe 2V operation (eeprom, included), 512-1kb flash, 32+ bytes ram, 50 cents in 100's, good hobby-level programming toolset at low cost, code protection _not_ needed, SOT-23-6, -20C to 85C temp range, internal programmable pullup and pulldown at roughly 22k ohm per I/O pin (not weak 100k+) with active high/low drive available, 10mA sink, 5mA source per pin or better.... did I mention a timer, sleep capability, wakeup on pin change, .... and very low power? Actually, it's the BOR and POR that are more crucial. I like these for specialized power-on reset and brown-out chips for other micros which don't have the brown-out built in. I often want to include a manual switch for resetting the board, as well. The _many_ SOT-23s out there for this kind of purpose do _not_ include the programmable brown-out nor the ability to store some info in eeprom, for example, and I want it all in one at similar price and size. I don't want to buy 10 boxes of almost-the-same chips. Rather just program up what I want from a single part number. Jon

You missed Temperature sense ?

I think Atmel chose to clone a PIC socket, and not look at the wider scope. Yes, EE is nice, but the paddle size in SOT23 is _very_ small, and EE has a high die cost. Perhaps in a _slightly_ larger package ? -jg

I don't need much EE. 8 bytes? But I think you are referring to the charge pump, which may be unavoidable over such a Vcc range? Of course, I also wanted 10mA sink, 5mA source ... or better. And that takes die space just for the fets alone. And the aluminum traces that carry that current, I suppose. But they benefit from not needing that many wire bond pads, yes? In any case, that's the application space for which I'd like a fill. Nice BOR and POR, ability to accept and debounce a manual switch, the ability for modest communications of parameters to the main cpu it is responsible for reseting and dealing with brown out situations, and tiny and cheap and versatile and ...

There has been a lot of discussion about them on AVR Freaks. Even the Tiny10 which was touted months ago isn't officially available yet, although one or two people have been able to get hold of a few samples. There doesn't appear to be any programming or debugging support for them yet in AVR Studio, but someone has manged to build his own programmer and write some software for it. Leon
