Power Requirements
Power consumption is extremely low for the automotive-grade eX devices due to the low capacitance of the antifuse
interconnects. The antifuse architecture does not require active circuitry to hold a charge (as do SRAM or EPROM),
making it the lowest-power FPGA architecture available today.
