Differences Between UltraScale FPGA Families - Differences Between UltraScale FPGA Families - UG570

This document uses the Kintex UltraScale and Virtex UltraScale families as the basis for descriptions and examples. The following defines some of the differences in the Artix UltraScale+, Kintex UltraScale+, and Virtex UltraScale+ families:

• Master serial and master SelectMAP configuration modes are not supported in the UltraScale+ FPGAs. These modes are not recommended in the other UltraScale families.
• The configuration interface can operate only at 1.8V or 1.5V in the UltraScale+ FPGAs. There is no CFGBVS pin in UltraScale+ devices. When migrating from an UltraScale FPGA to an UltraScale+ FPGA, the CFGBVS pin location becomes RSVDGND and must be connected to GND.
• The configuration timing and configuration rate options are different between UltraScale FPGAs and UltraScale+ FPGAs. The configuration frame size is 123 32-bit words in UltraScale FPGAs and 93 32-bit words in UltraScale+ FPGAs.
