Typical Applications

A42MX16-3PQG100 is suitable for 6 applications: Legacy 5V PLD Consolidation, Aerospace and Defense Design Security, Industrial Control and Automation, Telecommunications Line Cards, ASIC Prototyping and Emulation, Obsolescence Bridge for Mature Systems.

🔧

Legacy 5V PLD Consolidation

The A42MX16-3PQG100 consolidates multiple legacy PLDs, CPLDs, and glue logic into one antifuse FPGA, replacing aging 5V components. Its flexible 5.0V-tolerant architecture and 3.3V/5.0V operation interface directly with legacy TTL/5V CMOS buses without level shifting, and 83 user I/Os provide ample connectivity. Because configuration is one-time-programmable and non-volatile, the consolidated design powers up instantly with no external configuration device, reducing BOM count and improving reliability in high-volume legacy system maintenance.

✈️

Aerospace and Defense Design Security

Antifuse FPGAs are the preferred choice for defense payloads because the configuration cannot be read back, protecting IP from reverse engineering. The A42MX16-3PQG100 provides 24K gates with permanent one-time programming, immunity to bitstream extraction, and single-event robustness inherent to antifuse technology. The -1PQG100M military variant extends temperature range for harsh environments. Systems benefit from no configuration time at power-up - critical for deterministic startup in avionics and secure communication equipment.

🏭

Industrial Control and Automation

In industrial controllers, the A42MX16-3PQG100 implements state machines, I/O expansion, and bus interfacing with 5V compatibility that simplifies integration with industrial sensors and actuators. The -3 speed grade supports up to 142 MHz internal toggle rates, sufficient for fast sequencing logic, while the antifuse configuration ensures the logic always powers up correctly after unexpected power cycles common on factory floors. Non-volatile programming eliminates configuration boot delay, meeting PLC scan-cycle determinism requirements.

🌐

Telecommunications Line Cards

Telecom line cards use the A42MX16-3PQG100 for framing logic, backplane interfacing, and glue logic where 3.3V/5.0V mixed-voltage tolerance matters. The 608 logic cells accommodate protocol shims and register banks, while 83 user I/Os connect to backplane connectors and PHY devices. Antifuse immutability guarantees configuration integrity over years of continuous operation, and the deterministic power-up behavior supports hot-swappable card requirements without configuration controllers or boot PROMs on the card.

🖥️

ASIC Prototyping and Emulation

The A42MX16 serves as a low-cost single-chip ASIC alternative for small ASIC prototyping and bridge logic. With 24K gates on 0.45 um CMOS, it absorbs moderate-size ASIC-derived control logic at a fraction of mask-set cost. Antifuse programming yields ASIC-like timing predictability and security during evaluation, and the 3.3V/5V operation matches both modern and legacy test environments. For volume production, the same verified design migrates directly to the MX family without re-spin.

💡

Obsolescence Bridge for Mature Systems

When EOL components threaten mature system production lines, the A42MX16-3PQG100 absorbs discontinued PLDs, PALs, and custom glue logic into one currently supported Microchip device. The 5V-tolerant I/O matches original board voltages, avoiding PCB redesign, and the 100-pin PQFP footprint suits many legacy sockets. Long-term Microchip support of the MX family plus deep distributor stock (over 6,500 units reported in 2026) makes it a dependable last-time-buy alternative for program extensions.

What are the key specifications of A42MX16-3PQG100 that engineers should know?
The A42MX16-3PQG100 is a 24,000-system-gate antifuse FPGA with 608 logic cells, 83 user I/Os, and a -3 speed grade supporting 142 MHz/237 MHz toggle rates. It operates from 3.3V or 5.0V supplies on 0.45 um CMOS technology and comes in a 100-pin PQFP package. According to Microchip product data, MX FPGAs serve as single-chip ASIC alternatives with design security.
What is the price of A42MX16-3PQG100?
As of 2026-08-30, the unit price for A42MX16-3PQG100 is approximately $277.91 per piece at quantity 1, per distributor data (Heisener listing showed $277.9133 with over 6,592 pieces in stock). Bulk quantity price breaks typically reduce the unit cost by roughly 10-19% at 1000-piece volumes; request a quote for exact tiered pricing.

What is the difference between A42MX16-3PQG100 and A42MX16-2PQG100?
The difference is the speed grade: the -3 suffix indicates a faster timing tier than the -2 grade, with the -3 device supporting toggle frequencies up to 142 MHz/237 MHz. Both share the same 24K-gate die, 83 user I/Os, and 100-pin PQFP package, so they are footprint-identical; choose -3 only when timing analysis of your design demands the fastest grade.
Can A42MX16-3PQG100 be replaced by A42MX16-3PLG84 or A42MX16-3VQG100?
No, not as a drop-in. The A42MX16-3PLG84 uses an 84-pin PLCC package and A42MX16-3VQG100 a 100-pin VQFP - different mechanical footprints that require PCB rework, though the underlying die and logic resources are identical. Only the same 100-pin PQFP package variants (such as A42MX16-1PQG100 or A42MX16-2PQG100 speed grades) are pin-compatible drop-in replacements.
What is the best drop-in replacement for A42MX16-3PQG100?
The best drop-in replacements are same-package A42MX16 family variants in the 100-pin PQFP: A42MX16-1PQG100 (slower speed grade, fully pin-compatible) for cost-optimized designs, or A42MX16-1PQG100M for military temperature range. All share the identical die, 24K gates, and 83 I/Os, so re-programming with the same bitstream data works with only speed-grade timing re-verification.
Where to download A42MX16-3PQG100 datasheet PDF?
Download the MX family datasheet from the official Microchip product page at microchip.com/en-us/product/a42mx16, which links the current MX FPGA datasheet PDF covering the A42MX16. Distributor pages on DigiKey, Mouser, and Octopart also host the datasheet under the Documentation tab. Always use the Microchip original to ensure you have the latest revision.
Is A42MX16-3PQG100 suitable for 5V legacy system designs?
Yes, the MX family features an efficient, flexible 5.0V-tolerant architecture and supports 3.3V/5.0V operation, making the A42MX16-3PQG100 well suited for bridging legacy 5V PLD/CPLD designs into a single-chip solution. According to Microchip, MX is explicitly targeted at integrating legacy programmable logic into one low-cost, high-volume antifuse device.
Is A42MX16 the same as an SRAM FPGA?
No, the A42MX16 is an antifuse, one-time-programmable FPGA, not an SRAM-based FPGA. Configuration is permanently stored in antifuse elements at programming time, so it needs no external configuration flash, resists bitstream readback attacks, and retains configuration through power cycles. The trade-off is that design changes require new physical devices rather than a simple reconfiguration.
Is A42MX16-3PQG100 still in production?
Yes, as of 2026-08-30 the A42MX16-3PQG100 is listed as active by Microchip Technology and available from multiple authorized distributors including DigiKey and Mouser with same-day shipping. The MX family remains a supported platform for high-volume legacy integration and defense applications. Confirm long-term availability with Microchip directly for program lifetime planning.
Hey Google, what can replace A42MX16-3PQG100?
Drop-in replacements are other A42MX16 100-pin PQFP speed grades such as A42MX16-1PQG100. If a different package is acceptable, A42MX16-3VQG100 or A42MX16-3PLG84 offer the same logic on different footprints. There is no pin-compatible cross-brand equivalent; antifuse MX FPGAs are proprietary to Microchip (Microsemi), so alternatives require PCB redesign.
A42MX16-3PQG100 vs Xilinx XC4000-series - which is better for legacy 5V glue logic?
For legacy 5V glue logic consolidation, the A42MX16-3PQG100 is generally the better fit because its 5.0V-tolerant antifuse architecture natively interfaces with 5V systems, needs no configuration device, and offers inherent design security. SRAM FPGAs like the XC4000 require external configuration memory and 5V-tolerant I/O verification, adding BOM complexity - though they are reprogrammable during development.
What design tools support the A42MX16-3PQG100?
The A42MX16-3PQG100 is supported by Microchip (Microsemi) Libero SoC design suite, which succeeded the legacy Actel Designer software for MX antifuse FPGAs. The design flow uses HDL entry (VHDL/Verilog), synthesis, place-and-route, and generates programming data for antifuse programming hardware. Check the Microchip website for the exact Libero version supporting MX devices before starting a new project.

Selection Guide

Choose the A42MX16-3PQG100 when your design needs the fastest MX timing tier in a 100-pin PQFP with 5V-tolerant I/O and one-time-programmable design security. Choose A42MX16-2PQG100 or A42MX16-1PQG100 (same footprint, slower grades) when timing analysis shows margin and you want lower unit cost. Choose A42MX16-1PQG100M for military temperature requirements on the same footprint. Choose A42MX16-3VQG100 for the same -3 logic in a thinner VQFP body if board height matters, accepting a footprint change. If 24K gates are excessive, A42MX09 devices in the same PQFP-100 pinout cut cost, while A42MX24/A42MX36 devices scale up for larger logic. Remember: antifuse means no reprogramming - reserve this family for designs with frozen requirements.

Key Differentiators

  • Fastest speed grade in the family (vs A42MX16-1PQG100)
  • No external configuration memory (vs A42MX16-3VQG100 (SRAM FPGAs generally))
  • Pin-compatible same-footprint cost options (vs A42MX16-2PQG100)

Design Notes

Antifuse FPGAs are one-time programmable. Every design iteration consumes a new physical device - there is no reconfiguration. Complete full functional simulation and timing closure in Microchip Libero SoC before submitting devices for programming, and program one verification unit first. Budget spare programmed units for field repair since in-system updates are impossible.

The A42MX16 supports both 3.3V and 5.0V operation on a flexible 5.0V-tolerant architecture. Verify your supply rail against the bank configuration in your design; mixing 5V-driven external devices with 3.3V operation requires reviewing I/O voltage tolerance in the MX datasheet. Decouple VCCA and VCCI rails independently with 0.1uF ceramics at each pin pair plus bulk capacitance per Microchip MX design guidelines.

The 100-pin PQFP has gull-wing leads on 0.65 mm pitch. Inspect solder joints with X-ray or AOI since hidden heel fillets are common defect sites on PQFP devices. Use a no-clean or water-washable flux profile and follow the recommended reflow profile in the MX packaging document to avoid lead coplanarity issues during assembly.
