Typical Applications
A42MX16-1VQG100 is suitable for 6 applications: Legacy PLD Integration, Industrial Motor Control Interface Logic, Defense and Avionics Legacy Systems, 5V Microprocessor Glue Logic and Bus Bridging, Secure Industrial Control and Anti-Tamper Logic, Test and Measurement Fixture Logic.
Legacy PLD Integration
The A42MX16-1VQG100 consolidates multiple 22V10 PALs, GALs, and smaller PLDs from legacy boards into one 24K-gate antifuse device on a single 5.0V rail. Because the MX16 accepts 5.0V-tolerant I/O environments, it interfaces directly with legacy TTL-level buses without level shifters, eliminating two or three voltage domains. After one-time antifuse programming the design is permanently fixed, matching the deterministic behavior of the replaced fixed-logic devices. A typical consolidation replaces 3-5 PLDs, cutting board area, BOM count, and qualification effort in long-lifecycle industrial programs.
Recommended
Industrial Motor Control Interface Logic
In industrial drives, the A42MX16-1VQG100 bridges microcontroller PWM outputs to gate-driver and protection circuits, implementing dead-time logic, fault latching, and encoder decoding with sub-100 ns -1 speed-grade delays. The instant-on antifuse behavior means control logic is active within microseconds of power application - before soft-start completes - which is essential for safe power-up interlocking in 5.0V industrial environments. Its 83 user I/Os accommodate encoder quadrature inputs plus six PWM channels and fault feedback simultaneously, all in one 100-TQFP package with proven long-term availability.
Recommended
Defense and Avionics Legacy Systems
The antifuse MX16 suits defense and avionics platforms because its programmed configuration cannot be read back and contains no configuration memory to corrupt under radiation or power disturbance. The A42MX16-1PQG100M military-flow variant shares the same die for programs requiring higher screening levels. Designs qualified years ago on MX silicon can be re-sourced without redesign, since Microchip maintains the family for legacy programs. The 5.0V architecture matches MIL-STD-era bus levels, and one-time programming guarantees the flight-critical netlist is identical in every shipped unit.
Recommended
5V Microprocessor Glue Logic and Bus Bridging
Legacy 5.0V microprocessor systems require address decoding, wait-state generation, and interrupt arbitration at true 5V logic levels. The A42MX16-1VQG100 natively operates from a 5.0V supply, so its 83 I/Os drive and receive TTL/CMOS 5V buses directly without level translators, unlike modern 3.3V or lower FPGAs. The -1 speed grade easily meets classic bus timing of tens of nanoseconds. One 100-TQFP device typically replaces several 74-series decode and latch functions, reducing board complexity while preserving the exact fixed timing of the original discrete implementation after programming.
Recommended
Secure Industrial Control and Anti-Tamper Logic
Antifuse programming gives the A42MX16-1VQG100 inherent design security: there is no bitstream to intercept and no readback path, so proprietary control algorithms stored in the interconnect cannot be cloned by decapping competitors' devices. This matters for industrial equipment vendors protecting specialized machine-control IP on long-production boards. Combined with instant-on non-volatile behavior, the device also prevents boot-time attacks that target SRAM FPGA configuration loading. Designs are compiled in Libero SoC and programmed once, after which security no longer depends on supply-chain handling of configuration files.
Recommended
Test and Measurement Fixture Logic
Production test fixtures benefit from the A42MX16-1VQG100's instant-on, fixed-function behavior: the fixture logic is guaranteed identical on every power cycle and every unit, with no configuration download step adding test-cycle time. The 5.0V supply matches the TTL signaling common on legacy test equipment backplanes, and 83 I/Os cover channel expansion matrices and pass/fail combinational logic. Because each programmed device is permanently configured, fixture designs ship with verified units and cannot drift from the approved netlist - a frequent audit requirement in regulated manufacturing environments.

Key Differentiators
- Non-volatile instant-on operation with zero boot time (vs SRAM-based FPGAs (e.g., Xilinx XC4000))
- Readback-proof design security (vs SRAM FPGA families)
- Native 5.0V architecture (vs A42MX16-1PLG84 (same die, 84-PLCC))
Design Notes
The A42MX16 is one-time programmable - antifuse links cannot be reset. Complete full RTL simulation, timing closure, and ideally a hardware prototyping pass before releasing a programming file. Keep the Libero SoC project and programming file under revision control with checksums, because the programmed part cannot be re-read to recover the netlist.
The MX16 operates from a single 5.0V rail. During antifuse programming, dedicated programming current paths activate - consult the DS2136 datasheet programming specification for programmer supply requirements. In application, provide local 0.1uF decoupling per VCC pin pair plus 10uF bulk, and account for antifuse FPGA static-dominant current, which is lower and steadier than SRAM FPGA dynamic current but spikes during clocked operation.
The 100-TQFP (0.5 mm lead pitch) requires careful solder-paste stencil design to avoid bridging. Tie unused user I/Os per the datasheet recommendation (typically grounded via the Libero unused-pin setting) rather than leaving them floating, which can cause static current increase and noise susceptibility. Connect all VCC and GND pins; do not leave any supply pin unconnected even if the design uses few I/Os.
Compliance Information
Distributor listing (PCB Electronics) marks A42MX16-1VQG100 as LEAD FREE. Full RoHS/REACH certificates should be requested from Microchip.
