MAXII to MAX5 CPLD foot print compatability

Dear Team We are chaning MAX CPLD II EPM2210F256C5N with MAX V CPLD 5M2210ZF256I5N . 1. Are both CLPDs foot print compatiable? 2. In my old design for MAXII VCCINT 3.3V is there and Now I am chang...

    Hi,
    It's all described in device handbook and datasheet.

    GPIO have weak pull-up resistors to respective VCCIO until user mode becomes active. State of unused pins can be globally selected in Quartus device and pin options.

    "Reserves all unused pins on the target device in one of 5 states: as inputs that are tri-stated, as outputs that drive ground, as outputs that drive an unspecified signal, as input tri-stated with bus-hold, or as input tri-stated with weak pull-up."

    Personally, I won't choose high-Z without pull-up if there are any unconnected GPIO pins because floating inputs can involve additional device current consumption.

    Regards
    Frank

Regarding the issue of EPM2210F256C5N $50 and 5M2210ZF256I5N $29 out of stock, discontinued production, replacement, and large-scale ordering, we have set up a special team to conduct research and achieved good results. Are you interested in joining?
