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 operat-
ing 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 parame-
ters included are common to popular designs and typical
applications.

able on the Xilinx website:
