Schematic for ATTINY2313 Programmer

[mackscb]

Anyone seen a schematic or how-to for the programmer for the attiny2313 chip? I have the one from the Mountainman software, but would like to know some info on what to buy for the 3.57mhz crystal.

I'm trying to buy the crystal to build the attiny2313 programmer. I have found one that has a load impedance of 18 pf and drive level 0.5mW fundamental frequency. The other one has inpedance listed as series and drive level as 4.0mW maximum.

Which one would be the correct one to use?

You shouldn't need a crystal/x-tal with the simple programmer for the Attiny2313 chip. It should be almost exactly like the simple programmer for the Atmel2313, but with a slightly different layout. I havn't found a schematic yet, but will post it if I find it. Havn't looked very hard yet either since I don't have any Attiny chips.

I have found two schematics. One is the one in the MountainMan software and the other I can't remember where I found it. Both show the crystal. I can post those if you like.

Can you do attachments now. Last couple of times I tried it, I couldn't make it work.

Here are the schematics I have.

I need to use the 2-ChipRom103Rev38b.hex flash to setup my 625 and I would like to know if this flash can be used on the attiny2313 chip? Can/should it be programmed with the Mountainman software?
