General Description

ProASIC3E, the third-generation family of Microsemi flash FPGAs, offers performance, density, and features beyond those of the ProASICPLUS? family. Nonvolatile flash technology gives ProASIC3E devices the advantage of being a secure, low power, single-chip solution that is Instant On. ProASIC3E 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.
