This ISP programmer circuit, based on AT90S1200 device.

I found the schematic of this programmer in my "AVR software and technical Library - April 2003" CD-rom and decide to publish it. The reason was, that this programmer is very stable and works perfect with AVR Studio 4.  I had tested it before published it, with AT90s2313 and its worked fine!!!

To work this programmer you must to connect a crystal  4MHz to slave device at the XTAL1 and XTAL2 pins, or if you have an device with internal oscillator (AT90S2343, ATmega161 etc) and its enabled , its not need any external oscillator.

If you want you can use MAX232 or MAX202 instead transistors, capacitors and resistors to connect master AT90S1200 with Personal Computer (PC). There is no problem (i check this hardware by using MAX202).

More AVR devices ?

John Samperi made some modifications to the AVR910.asm file and create the AVR910_2313_v3.asm. This code can program more devices than AVR910.asm v2.2 does. The AVR prog 1.37 show all this devices. I don't know if really program them with v3.0. All devices that ( maybe) can be programmed by version 3 are:

 Hardware modifications:

- Instead of BAS16 diodes you can use 1N4001

- Instead of BC847C you can use BC547C

- Instead of BC857C you can use BC557C
