Axcelerator FPGAs

The Axcelerator Family of Antifuse FPGAs

Axcelerator, our antifuse family of FPGAs, offers high performance and unprecedented design security at densities of up to 2 million equivalent system gates.

Utilizing our AX architecture, Axcelerator devices have several system-level features, such as embedded SRAM (with embedded FIFO control logic), PLLs, segmentable clocks, chip-wide highway routing and the ability to carry logic.

Developed with a CMOS antifuse process technology based on 0.15 µm and seven layers of metal, Axcelerator devices offer a level of performance previously only available in ASIC technology.

Key Benefits of Axcelerator FPGAs

The Axcelerator FPGA family is a single-chip, nonvolatile solution offering high performance and unprecedented design security at densities of up to 2 million equivalent system gates. Utilizing the AX architecture, Axcelerator devices have several system-level features, such as embedded SRAM (with embedded FIFO control logic), PLLs, segmentable clocks, chip-wide highway routing and carry logic. The solution is based on a 0.15-μm, seven-layers-of-metal CMOS antifuse process technology and 350-MHz system performance.
