A cheap option for low-power, high-performance designs is the eX series of FPGAs. These devices are perfect for power-sensitive applications due to the antifuse technology's inherent low power characteristics and an additional low static power mode. These devices are produced using cutting-edge 0.22 mm CMOS antifuse technology, which results in great performance with negligible power loss.
Using 0.22 m design criteria, the Microsemi eX family is realized on a high-voltage twin-well CMOS technology. With almost no chip area lost to connection components or routing, the eX family architecture has a "sea-of-modules" design where the whole floor of the device is covered with a grid of logic modules.
Metal-to-metal programmable antifuse connector elements, a Microsemi invention, are used to connect these logic modules together. The antifuse connection has a "on" state resistance of 25 and a capacitance of 1.0 fF for low-signal impedance. It is constructed from amorphous silicon, dielectric material, and barrier metals. When programmed, the antifuses, which are by default open circuit, create a stable low-impedance connection.
