attiny861

Hi!
I'm interested in to programming the attiny861 via the arduino. I'm succesfully programmed the attiny84, attiny2313, attiny 45. But I can't find the attiny861 core to arduino ide, to do the programing. Is there a way to use the attiny with the arduino?
Thanks in advance, and sorry for the bad english, I'm not a native english speaker.

This supports the ATTin861:

Thanks!
But it support the 861 only in 1mhz and 18,432mhz?

You can add more frequencies very easily.

Open the boards.txt file for the core and add more entries.

For example, this is for 8MHz:

attiny861at8.bootloader.extended_fuses=0xFF
attiny861at8.bootloader.path=empty

attiny861at8.build.mcu=attiny861
