Hi,

I have no PCA with MAX3000A device at hand right now, but I presume configuration can be read-out with programmer examine funtion, as long as security bit isn't set.

To operate JTAG interface, you need to connect JTAG and all power supply pins and apply 3.3V power supply. Coonnection according to pinout file.

MAX3000A programming is however also possible with some industry standard universal programmers. The datasheet mentions Data I/O and BP Microsystems.

Why you are trying to program MAX3000A without fitting it into a circuit with JTAG connection?

Hello, I actually want to read and back up the data in the chip I have. What I understand from what you said is that I need to connect the USB blaster to the bus pins on the chip and also supply 3.3v to the chip? Can you help me with the pins? There are 3.3v inputs on all sides of the card. Can you give me a reference point? Can I read the data on the card with the Quartus II 13.0sp1 program and write it to the same new chip?
