Spartan-XL Family DC Characteristics Over Operating Conditions
Supply Current Requirements During Power-On
Spartan-XL FPGAs require that a minimum supply current
I
on. If more current is available, the FPGA can consume
more than I

A maximum limit for I
using foldback/crowbar supplies and fuses. It is possible to
control the magnitude of I
available to the FPGA. A current limit below the trip level will
avoid inadvertently activating over-current protection cir-
cuits.
