eX FPGAs

eX Family of Antifuse FPGAs

The eX family of FPGAs meets all of your power, speed, package and price requirements. We optimized eX devices for wired and portable e-appliances, allowing you to use a flexible, single-chip FPGA for their traditional low-density ASIC requirements.

Key Benefits

Low power consumption
Ability to be live at power-up
2.5V, 3.3V and 5.0V mixed-voltage operation with 5.0V input tolerance and 5.0V drive strength
Up to 100% resource utilization with 100% pin locking
FuseLock secure programming technology that prevents reverse engineering and design theft
Availability in automotive temperature grades
