Operating from a 5.0V supply, this device supports system speeds up to 192 MHz and is fabricated on a 0.45 um process, with an automotive-grade temperature rating (suffix A). An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements custom digital circuits after manufacturing. The 42MX family uses antifuse programming technology, which is one-time programmable (OTP): connections are permanently formed at programming time. Antifuse FPGAs are prized over SRAM FPGAs for their low power, high immunity to radiation and configuration errors, and instant-on behavior, making them a reliable, single-chip ASIC alternative for high-volume, cost-sensitive designs and legacy PLD consolidation. Key features include the efficient 5.0V MX architecture, which tolerates 5V-tolerant I/O environments common in industrial and legacy systems, high gate density per cost point, and the A-suffix automotive screening. With 14K gates the device suits moderate-complexity state machines, glue logic, bus interfaces, and control-plane designs that previously consumed multiple PLD devices. Architecturally, the MX fabric consists of combinatorial and sequential modules organized into clusters, with antifuse interconnect providing low on-resistance routing that contributes to deterministic, near-ASIC timing. Unlike SRAM-based FPGAs, no boot PROM is required, reducing BOM cost and configuration-time attack surfaces. Typical applications include industrial automation controllers, automotive subsystems, telecommunications line cards, medical instrumentation, and drop-in replacement of multiple 5V CPLDs/PLDs in legacy redesigns. Design consideration: because the device is one-time programmable, verify the design thoroughly in simulation before programming; plan revision strategy with the Microchip Libero/Designer flow, and reserve the A-grade variant for automotive-qualified programs.

Fabricated on a 0.45 um CMOS process, it operates from a dual 3.3V/5V supply and achieves toggle rates of 119 MHz to 198 MHz depending on routing tier. The '-1' speed grade and 'I' suffix denote standard speed and industrial operating temperature range (-40C to +85C). An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up programming time via antifuse links. Unlike SRAM FPGAs, antifuse programming is one-time and non-volatile, so the device retains its configuration with no external boot flash and inherently resists bitstream readback - a key reason the MX family serves as a single-chip ASIC alternative and legacy PLD consolidation platform. Within the power-management hierarchy of programmable logic, the MX family sits between simple CPLDs and high-density SRAM FPGAs. Key features include the flexible 5.0V-tolerant MX architecture, low cost per gate for high-volume production, no configuration PROM requirement, and security through non-readable programming. The 100-TQFP surface-mount package supports standard reflow assembly, and the industrial temperature rating suits harsh environments. Architecturally, the 42MX16 combines combinatorial and sequential logic modules connected through segmented antifuse interconnect, delivering deterministic timing without configuration-load transients. Performance tiers (119 MHz/198 MHz) reflect different routing resources. Typical applications include glue logic integration, industrial control, legacy ASIC/PLD replacement, military/aerospace subsystems requiring configuration security, and high-volume consumer boards where per-unit cost dominates. Design consideration: antifuse devices are one-time programmable - verify logic thoroughly in simulation and, ideally, on a companion deviice or emulation target before committing to production programming. Follow the DS2136 datasheet for power decoupling (0.1 uF per VCC pin) and JTAG boundary-scan programming requirements.
