Combining Advanced Silicon Modular Block (ASMBL™) architecture with a wide variety of flexible features, the Virtex®-4 family from Xilinx greatly enhances programmable logic design capabilities, making it a powerful alternative to ASIC technology. Virtex-4 FPGAs comprise three platform families LX, FX, and SX offering multiple feature choices and combinations to address all complex applications.

The wide array of Virtex-4 FPGA hard-IP core blocks includes the PowerPC® processors (with a new APU interface), tri-mode Ethernet MACs, 622 Mb/s to 6.5 Gb/s serial transceivers, dedicated DSP slices, high-speed clock management circuitry, and source-synchronous interface blocks. The basic Virtex-4 FPGA building blocks are enhancements of those found in the popular Virtex, Virtex-E, Virtex-II, Virtex-II Pro, and Virtex-II Pro X product families, so previous-generation designs are upward compatible. Virtex-4 devices are produced on a state-of-the-art 90 nm copper process using 300 mm (12-inch) wafer technology.

Artix®-7 FPGAs are available in -3, -2, -1, -1LI, and -2L speed grades, with -3 having the highest performance. The Artix-7 FPGAs predominantly operate at a 1.0V core voltage. The -1LI and -2L devices are screened for lower maximum static power and can operate at lower core voltages for lower dynamic power than the -1 and -2 devices, respectively. The -1LI devices operate only at VCCINT = VCCBRAM = 0.95V and have the same speed specifications as the -1 speed grade. The -2L devices can operate at either of two VCCINT voltages, 0.9V and 1.0V and are screened for lower maximum static power. When operated at VCCINT = 1.0V, the speed specification of a -2L device is the same as the -2 speed grade. When operated at VCCINT = 0.9V, the -2L static and dynamic power is reduced.

Artix-7 FPGA DC and AC characteristics are specified in commercial, extended, industrial, expanded (-1Q), and military (-1M) temperature ranges. Except the operating temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a particular speed grade (that is, the timing characteristics of a -1M speed grade military device are the same as for a -1C speed grade commercial device). However, only selected speed grades and/or devices are available in each temperature range. For example, -1M is only available in the defense-grade Artix-7Q family and -1Q is only available in XA Artix-7 FPGAs.

All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications.
