Hi all,
My company is facing a serious problem, we have an important module that is supplied from outside using an ALTERA FLEX6000

The model number is
"EPF6024AQC208-3"

Unfortunately, the supplier was closed recently, and we are now running out of spare modules. Concurrently when we are now seeking for legal consultations, since the module's IP was partly held by our company. I would like to ask is it possible to do the clone actually?
 

It is a while since I used the Flex 6000 but I seem to remember they are SRAM based and the programming is normally done with an EEPROM. If that is the case, it should be easy to duplicate - the data is not encrypted. It could be loaded from a device such as a microcontroller instead, which would be more tricky as that could be code protected. If you have the circuit diagram or a physical board, look for a small 8 pin EEPROM next to the Flex 6000. There would most likely be a JTAG programming connector as well.

Thanks Keith, I ve found an ALTERA EPC2LC20.
Since Flex6000 is SRAM based, does it mean there should be 'nth' inside the Flex6000 that I need to retrieve?

Also, It seems that there is no MCU on the board for encryption, thank you.
 

You should be fine - just copy the EPC2LC20. Nothing is permanently stored in the Flex 6000. Is there a JTAG connector? If not I assume the EEPROM is programmed before fitting to the board.

Yes, there is a JTAG connector as you mentioned.
Thank you so much for your great help~~~
So only thing I have to do is to copy the EEPROM, am i right?
 

Correct.

As I said, it is a while since I used the Flex 6k but I think you should be able to read the EEPROM on your existing board through the JTAG. I used to use the Altera Byteblaster to do that but there will be a newer low cost programmer from Altera I would think (USB based maybe).

USB Blaster is probably what you need:
