It operates from a 5.0V supply, supports clock rates up to 153 MHz, and is fabricated on a 0.45 um process. The A suffix denotes automotive-grade screening, making it suitable for harsh-environment and high-reliability systems. An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements digital circuits through a fabric of configurable logic blocks, flip-flops, and routing resources. Unlike SRAM-based FPGAs, the MX family uses antifuse programming technology, which is one-time programmable (OTP): the configuration becomes permanent at power-up with no boot time and no external configuration memory required. Key features include the flexible 5.0V architecture that directly interfaces with legacy 5V TTL and 5V PLD logic, low power consumption, inherent design security (no bitstream to steal), and the single-chip ASIC-alternative positioning Microchip promotes for high-volume designs. The MX family is an ideal platform for integrating legacy PLDs and glue logic into a single low-cost device, and its antifuse fabric is immune to configuration-upset issues that affect SRAM FPGAs in radiation-prone environments. Architecturally, the 42MX device combines combinational modules and sequential modules arranged in a sea-of-modules fabric with dedicated routed clocks. Logic capacity is expressed as 24K system gates with 608 usable cells, and the device achieves 153 MHz toggle performance on a 0.45 um CMOS process. Design entry is performed with Microchip Libero SoC design tools targeting the MX families. Typical applications include legacy 5V system redesigns, industrial control, defense and aerospace programmable glue logic, automotive control modules, and bridging between microprocessors and peripheral logic where 5V tolerance and instant-on operation matter. Design consideration: because the device is one-time programmable, verify the design fully in simulation and, where practical, prototype on a larger-density MX device before committing to production programming.

The device includes dedicated routing resources and I/O registers to support high-speed data paths and complex state machines. Typical applications include industrial control, automotive electronics, communications infrastructure, and test and measurement equipment. The 5.0 V operation makes it particularly suited for interfacing with legacy 5 V logic families, while the 125 I/Os allow integration of multiple PLDs into a single device, reducing board space and cost. When designing with this FPGA, ensure adequate decoupling on the VCC and GND pins, and follow the manufacturer's guidelines for configuration and JTAG connections. The device is non-volatile in the sense that it can be configured from an external PROM, but it is not flash-based, so configuration data must be reloaded at each power-up.

The antifuse fabric eliminates configuration PROMs, reducing bill-of-materials count and improving reliability in high-vibration and radiation-sensitive environments. Technically, the device provides 608 logic elements (cells) organized into the MX compile-and-route fabric supported by Microchip Libero SoC design software. Because configuration is one-time programmable, designs benefit from latch-up immunity to bitstream upset, and no external flash is required - a decisive advantage in defense, avionics, and industrial systems where configuration integrity is mandatory. Typical applications include glue logic consolidation of legacy PLD/ASIC designs, industrial control interfaces, military and aerospace subsystems requiring secure non-reprogrammable logic, and communication backplane bridging where 5V-tolerant I/O remains essential. Designers should note that antifuse devices cannot be reprogrammed in-system; a programming pinout and programming equipment are required during production, so board bring-up should be planned with programming access in mind.
