It operates from a dual supply of 3.0V-3.6V (core/support) and 4.75V-5.25V (I/O), and is rated for commercial 0C to +70C ambient operation. Speed grade -2 denotes the faster timing bin of the family. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure to implement custom digital circuits. FPGAs sit between fixed-function ASICs and microprocessors in the programmable logic hierarchy. The MX family is distinctive for its one-time-programmable antifuse technology, which is non-volatile, inherently secure, and immune to configuration readback. Key features include the efficient 5.0V-tolerant architecture that makes MX an ideal single-chip ASIC alternative and a low-cost platform for integrating legacy PLD designs into one device. With 336 logic cells, up to 161 MHz/269 MHz internal performance paths, and 0.45 um antifuse process technology, the device suits high-volume, cost-sensitive production where solder-down certainty and design security matter more than reprogrammability. Architecturally, the MX fabric combines combinational and sequential modules with pervasive routing, delivering predictable, ASIC-like timing. Because the antifuse configuration is permanent, there is no need for an external boot flash, reducing BOM cost, board area, and configuration-time failure modes compared to SRAM FPGAs. Typical applications include industrial control, legacy 5V system redesigns, military/aerospace program derivatives of PLD-based designs, glue logic consolidation, and high-reliability embedded systems. Design consideration: because MX devices are one-time-programmable, verify your design thoroughly in simulation and with device programming before production commit; plan a 10-week manufacturer lead time when scheduling builds (as of 2026-08-30).
