Anyone knows of a ATTiny87 core that would work with the current IDE (I'm still running 1.0.5, until 1.5 rises out of beta phase)? 87 does not seem to be in the toolchain either.
I have a project with the code at a bit over 5k, and needing 16 digital I/O lines. Prototype, running on Pro Mini works and the project is about to get its own PCB... ATTiny87 looks just right...
How about Atmega8A?
Same memory, already in the toolchain: AtmegaNG with Atmega8
Take a look at this:
Currently the following processors are supported:
ATtiny84,44,24
ATtiny85,45,25
ATtiny861
ATtiny87/167
ATtiny2313
If ATMega8, not sure if I can solder MLF/TQFP... The ATTiny87 comes in SOIC, which I can deal with.
Thanks for the pointer to TCWORLD/ATTinyCore. I already saw it but was not clear about a few items: Can I use it with Arduino IDE (what about toolchain?) or do I need to use UECIDE then?
Watch from 21:10 to 21:45 to see how easy it is to do:
I have no particular skill and I can solder 240 pin 0.5mm parts and 144 pin 0.4mm parts with no trouble.
Watch the rest of the video and Dave will explain all.
DIP then?
Attiny87 is Only available as SMD.

A search of Attiny87s shows only SMT packages at Digikey:
Datasheet shows these packages, none DIPs:

Oh, you're right. No DIPs.
The top one will fit on a DIP adapter board though...

And, even low-pin count QFP/QFNs have DIP adapters available. I've used these and they work great.

Soldering on the QFNs can be a bit more tricky. The QFPs are relatively easy, IMHO.
Maybe you could use ATtiny861 .
It comes in DIP and is supported by Tom Carpenters core
You could go for the ATTiny167, which is supported. It is basically the same as the 87, but with more flash.
The only thing that doesn't support the 167 directly is avrdude, though if you add the lines from the attached file into your avrdude.conf file, it will work fine.
ATtiny167.conf (6.57 KB)
Hey Tom, have 87 entry for avrdude.conf?
