I require a PLC controller with DIO, AIO, Bluetooth, 64Bit process, industrial reliability. What do you suggest?

Dallas,
the link above has 15 processors recommended, all of them 32 bits.
If 64 bits architecture is a must, then we are recommending to you our AM6548 family that is sampling now. You have options of dual or quad core A53 that was designed for Industry 4.0 applications.

Thanks for considering our devices. I hope this helps.
