Introduction
Spartan®-7 FPGAs are available in -2, -1, and -1L speed grades, with -2 having the highest performance.
The Spartan-7 FPGAs predominantly operate at a 1.0V core voltage. The -1L devices are screened for lower
maximum static power and can operate at lower core voltages for lower dynamic power than the -1
devices. The -1L devices operate only at V_CCINT = V_CCBRAM = 0.95V and have the same speed
specifications as the -1 speed grade.
Spartan-7 FPGA DC and AC characteristics are specified in commercial and industrial 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 -1I industrial
speed grade device are the same as for a -1C commercial speed grade device). However, only selected
speed grades and/or devices are available in each temperature range. For example, the -1L speed grade is
only available in the industrial (I) temperature 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.
Available device and package combinations can be found in the 7 Series FPGAs Overview (DS180) [Ref 1].
This Spartan-7 FPGA data sheet, part of an overall set of documentation on the 7 series FPGAs, is available
