The ACTEL AX2000-CQ256M is an Axcelerator family antifuse-based Field Programmable Gate Array (FPGA) from Actel (Microsemi / Microchip), delivering 2,000,000 equivalent system gates on Actel's advanced 0.15µm 7-layer metal CMOS antifuse process. The "CQ256M" suffix identifies the 256-pin ceramic CQFP hermetic package and military M-grade temperature rating of –55°C to +125°C. As the highest gate density device in the Axcelerator family at standard speed grade, the AX2000-CQ256M offers maximum logic capacity in a compact hermetic package for military and aerospace programs where board space is constrained.
Unlike SRAM-based FPGAs, the ACTEL AX2000-CQ256M is nonvolatile and Live At Power-Up — no external configuration memory or boot device is required, and the device is inherently immune to single-event upsets (SEU) and firm errors. It features 295 Kbits of embedded SRAM with integrated FIFO control logic, dual PLLs, segmentable clock networks, chip-wide highway routing for predictable high-speed timing, and FuseLock security technology to permanently prevent design readback and IP theft. Multi-standard I/O support including LVDS at 700 Mb/s, HSTL, SSTL, GTL+, and PCI/PCI-X provides the interface flexibility required for demanding military system integration.
