I have a ALTERA MAX3000A CPLD with two inscriptions:
EPM3256AFC256-7 --> commercial temp, speed grade 7 and EPM3256AFI256-10 --> industrial temp, speed grade 10
I bought the industrial one. Are this two CPLDs equivalent??? If yes -> if I buy the commercial, speed grade 7 - is this CPLD equivalent to the industrial temp, speed grade 10???
Thanks for your answers in advance, Manfred
