Note that with higher voltage input supplies, such as 5V, power
dissipation in the linear regulator is of greater concern (see previously
presented power dissipation calculations).

3.3V Configuration
o
The Spartan-3 FPGA configuration and JTAG ports commonly use signals
with a 2.5-V swing. Alternatively, it is possible to use 3.3-V signals
simply by adding a few external resistors. The 3.3-V signals can cause a
reverse current that flows from certain configurations and JTAG input pins,
through the FPGA, to the V
