Typical Field Programmable Gate Array (FPGA)
Power Requirements
The flexibility of FPGAs
leads to the requirement for multiple supply voltages and
currents.
Core Voltage/Power
In large FPGAs, the logic core generally has the most
demanding current requirements, up to tens of amps depending
on the number of gates being used and the clock frequency.
Designated VCCINT by Altera, by
platform the voltage required is:
Stratix® and Cyclone® series = 1.5V
Stratix II series = 1.2V
I/O Voltage/Power
Designated VCCO and equal to 1.5V,
1.8V, 2.5V or 3.3V depending on the I/O standard selected.
I/O standards can be set independently by block in the FPGA,
so more than one I/O voltage for a single FPGA is possible.
