Cyclone® V FPGA & SoC FPGA Altera Cyclone® V FPGA and SoC FPGA devices come in commercial and industrial grades. Commercial options include -C6, -C7, and -C8 speed grades, while industrial-grade devices are offered in the -I7 speed grade. Automotive devices are available in the -A7 speed grade. Altera Cyclone V SoC devices also offer a low-power variant, denoted by the 'L' power option in the part number. These low-power devices reduce static power by 30% for 25K LE and 40K LE devices and by 20% for 85K LE and 110K LE devices. The L power option devices are exclusively in the -I7 speed grade and share operating conditions and timing specifications with the standard -I7 devices.
