General Description
ProASIC3, the third-generation family of Actel flash FPGAs, offers performance, density, and features beyond those of the ProASICPLUS® family. Nonvolatile flash technology gives ProASIC3 devices the advantage of being a secure, low-power, single-chip solution that is live at power-up (LAPU). ProASIC3 is reprogrammable and offers time-to-market benefits at an ASIC-level unit cost. These features enable designers to create high-density systems using existing ASIC or FPGA design flows and tools.
