Virtex-4 FPGA Data Sheet: DC and Switching Characteristics
DS302 (v3.7) September 9, 2009
Virtex-4 FPGA Electrical Characteristics
Virtex®-4 FPGAs are available in -12, -11, and -10 speed grades, with -12 having the highest performance. Virtex-4 FPGA DC and AC characteristics are specified for both commercial and industrial grades. 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 -10 speed grade industrial device are the same as for a -10 speed grade commercial device). However, only selected speed grades and/or devices might be available in the industrial range. All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications. This Virtex-4 FPGA Data Sheet is part of an overall set of documentation on the Virtex-4 family of FPGAs that is available on the Xilinx website: • • • • • • • • • Virtex-4 Family Overview, DS112 Virtex-4 FPGA User Guide, UG070 Virtex-4 FPGA Configuration Guide, UG071 XtremeDSP for Virtex-4 FPGAs User Guide, UG073 Virtex-4 FPGA Packaging and Pinout Specification, UG075 Virtex-4 FPGA PCB Designer’s Guide, UG072 Virtex-4 RocketIO™ Multi-Gigabit Transceiver User Guide, UG076 Virtex-4 FPGA Embedded Tri-Mode Ethernet MAC User Guide, UG074 PowerPC® 405 Processor Block Reference Guide, UG018
