The following examples provide some guidelines of device performance. The actual performance depends on the
specific application and how it is physically implemented in the iCE65P FPGA using the Lattice iCEcube2 software.
The following guidelines assume typical conditions (VCC = 1.0 V or 1.2 V as specified, temperature = 25 ˚C). Apply
derating factors using the iCEcube2 timing analyzer to adjust to other operating regimes.
