Chip Express builds rad-hard laser PGAs
NASA experts have tested laser programmable gate arrays (LPGAs) from Chip Express Corp. of Santa Clara, Calif., for radiation hardness and approved the devices for a range of space flight missions. The NASA tests were part of a program to evaluate the radiation tolerance of ASIC and FPGA devices to assure that in the drive to switch from special hardened devices to commercial off-the-shelf devices, that main elements of radiation protection are sustained. Laser programmable gate arrays offer "to
