SI Programmer

Posted on Feb 4, 2014

With the following circuit you can easily program the AVR microcontrollers AT90S1200, AT90S2313 (or ATtiny2313), AT90S8515 and AT90S4414, using the freeware programmer PonyProg by Claudio Lanconelli. You can download the program for free from the author`s website ( ). The simple SI-Prog is actually a simplification of the more complicated program

mer designed by Claudio Lanconelli, which is supporting a large number of programmable devices. Attention: The circuit includes an adaptor to extend the number of the supported AVR microcontrollers. Simply connect each pin of the adaptor to the appropriate pins of the microcontroller (MISO pin of the adaptor with MISO I/O of the microcontroller, etc) without using additional components. Remember to connect a piezoelectric crystal (usually 4, 8 or 10MHz) to the XTAL pins of the microcontroller or the programming procedure will fail. Note: With the newer AVR micros that include an internal crystal, you don`t need the additional piezoelectric crystal. If this is the case, you simply connect the adaptor with the appropriate pins of the microcontroller and you are ready to program!
