Xilinx FPGAs require at least two power supplies: VCCINTfor core circuitry and VCCO for I/O interface. For the latestXilinx FPGAs, including Virtex-II Pro, Virtex-II and Spartan-3, a third auxiliary supply, VCCAUX may be needed. Inmost cases, VCCAUX can share a power supply with VCCO.The core voltages, VCCINT, for most Xilinx FPGAs, rangefrom 1.2V to 2.5V. Some mature products have 3V, 3.3Vor 5V core voltages. TABLE 1 shows the core voltagerequirement for most of the FPGA device families. TypicalI/O voltages (VCCO) vary from 1.2V to 3.3V. The auxiliaryvoltage VCCAUX is 2.5V for Virtex-II Pro and Spartan-3, andis 3.3V for Virtex-II.
