Conclusion
MAX II devices can be used to incorporate logic and memory devices on a design
board, eliminating chip-to-chip delays, minimizing board space, and reducing total
system cost. Since you can program the UFM block to suit your needs, MAX II devices
offer more interface flexibility than an off-the-shelf EEPROM device.
