HELP! I blasted the ST72F264G2B5 MC on my EvalPractiSPIN board.

I have looked all over the web for replacement chips but Noooo.

The only ones I have found is ST72F264G2B6 and I have to buy 480 of them; Yikes

.

I only need a hand full < 5 for replacements if this failure occurs again.

Does anyone know where I can get some of these chips?

Are these obsolete?

I'm located a few miles from the St Wherehouse in Phoenix if that helps.

Thanks: Dennis

Hello Dennis. I'am your partner in this problem...like your.

now I 'm planning to re-produce the evalpractspin. I've only ST72264 mcu in SO version, but it's not a problem for me. Instead my problem is to have the FW, because the old MCU smoked for my error. So, I can reproduce the PCB craftmade using the SO MCU type but I haven't the FW. (from the ST's site it's possibile to update it only). do you think we can help ourself together? I can do two PCB and make a present of it for you. have you the FW or can you help me for this? contact me at

Hello,

after the installation process of EVALPRACTISPIN tool, in your root directory (tipically drive C:), inside ''Program Files/PractiSPIN'' folder there are three .s19 files (each one according to the motor type), that are the ST7's firmware binary files you are looking for.

I hope this helps you.

Best regards,

Tanio
