Space-grade, radiation-tolerant Virtex®-4QV FPGAs are available in the -10 speed grade and qualified for military (Tj = –55° C to +125° C) operational temperatures. Virtex-4QV FPGA DC and AC characteristics are specified for military temperatures only. 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 military device are the same as for a -10 speed grade industrial device).
