ProASIC3, the third-generation family of Microsemi 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 Instant On. 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.

ProASIC3 devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well as clock conditioning circuitry based on an integrated phase-locked loop (PLL). The A3P015 and A3P030 devices have no PLL or RAM support.

ProASIC3 devices have up to 1 million system gates, supported with up to 144 kbits of true dual-port SRAM and up to 300 user I/Os. ProASIC3 devices support the ARM Cortex-M1 processor. The ARM-enabled devices have Microsemi ordering numbers that begin with M1A3P (Cortex-M1) and do not support AES decryption.
