Is it possible to in-system programmability (ISP) update or program a MAX® II device design in the Configuration Flash Memory (CFM) without overwriting the contents of the User Flash Memory (UFM)?

Description

Yes, it is possible to ISP program the MAX II device design in the CFM without overwriting the content of the UFM. The opposite is also true - you can ISP program the UFM contents without overwriting the MAX II device design in the CFM. The Quartus II Programmer provides the option to individually program :

  • The MAX II device design stored in the CFM block
  • The entire user flash memory (UFM) block
  • Or the entire MAX II device (CFM and UFM content)
