Spartan-7 FPGAs Data Sheet: DC and AC Switching Characteristics DS189 (v1.9) March 13, 2019 Product Specification 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 =V = 0.95V and have the same speed CCINT CCBRAM specifications as the -1 speed grade. Spartan-7 FPGA DC and AC characteristics are specified in commercial (C), industrial (I), and expanded (Q) 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 -1Q expanded 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.

Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time might affect device reliability. 2. The lower absolute voltage specification always applies. 3. For I/O operation, refer to the 7 Series FPGAs SelectIO Resources User Guide (UG471) Ref 3 . 4. The maximum limit applies to DC signals. For maximum undershoot and overshoot AC specifications, see Table 4. 5. See Table 9 for TMDS 33 specifications. 6. For soldering guidelines and thermal considerations, see the 7 Series FPGA Packaging and Pinout Specification (UG475) Ref 4 .
