Hello Wlodek,
Thank you very much for your response. The linked informations you gave are exactly what I was looking for.
It removes a doubt about longevity of the DZ32 given by our distributor.
We use it for several years and plan to use it on a new developpement, (we also use QE16 on an other successful design)
(mains reasons are speed, 12 bits ADC, complete but simple modules, and quality of ducumentation)
Of course it can not compete with small DSP we also use but this is not the purpose.
Best regards from france
