Typical Applications
A42MX16-1PQG100 is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control and Automation, Obsolescence Management for Defense Systems, 5V Bus Interface Bridging, High-Volume Cost-Sensitive Logic Integration, Test and Measurement Instrument Logic.
Legacy PLD Consolidation
The A42MX16-1PQG100 is purpose-built for consolidating multiple legacy PLDs, GALs, and TTL glue-logic devices into a single low-cost 24K-gate FPGA. Its native 5.0 V architecture directly replaces aging 5V logic families without level translation, cutting board area and BOM count. In a typical consolidation, two to five 22V10-class PLDs plus address decoders fit into the 24K gates with margin. Because the antifuse configuration is non-volatile, no configuration PROM is needed on the bill of materials, keeping the replacement cost and provisioning simple for long-life production programs.
Recommended
Industrial Control and Automation
In industrial control and automation boards, the A42MX16-1PQG100 implements state machines, motor-control sequencing, and bus-interface logic that must tolerate 5V signaling environments. The 83 user I/O provide sufficient pin count for parallel fieldbus interfaces and sensor polling, while the -1 commercial speed grade comfortably meets sub-100 MHz control logic timing. Antifuse configuration is immune to power-glitch corruption, an important reliability trait on factory floors with unstable power, and IEEE 1149.1 JTAG boundary scan supports in-circuit production test of assembled control boards.
Recommended
Obsolescence Management for Defense Systems
Defense and avionics sustainment programs use the A42MX16-1PQG100 and its military-grade siblings to keep legacy 5V programmable logic in production after original PLD vendors exit the market. Microchip maintains the MX family specifically as a long-term platform for such programs. The 100-pin PQFP with gull-wing leads is easy to inspect and rework during depot-level repair, and the one-time-programmable antifuse technology provides inherent tamper resistance and configuration security valued in defense platforms where configuration readback must be impossible.
Recommended
5V Bus Interface Bridging
The device serves as a bridge between legacy 5V parallel buses (VME-style backplanes, ISA-derived interfaces) and newer subsystem logic. With 83 I/O operating at 5.0 V, it drives and receives TTL-level signals directly, eliminating bus transceiver banks. The MX architecture's wide-decode capability implements address decoding and chip-select generation efficiently in the 24K gates. Designers should budget I/O clamp considerations and follow datasheet DS2136 DC specifications for VOH/VOL at required drive currents to guarantee bus timing margins across the commercial temperature range.
Recommended
High-Volume Cost-Sensitive Logic Integration
For consumer and industrial products in volumes above roughly 10K units per year, the A42MX16-1PQG100 functions as a low-cost single-chip ASIC alternative: no NRE mask charges, immediate design changes, and non-volatile configuration that removes firmware provisioning from the assembly line. The antifuse technology makes cloned re-programming impossible, protecting logic IP in cost-sensitive markets. At the ~$258 unit price point as of 2026-08-30 it targets programs where reliability and IP security outweigh the per-unit cost of modern low-voltage FPGAs.
Recommended
Test and Measurement Instrument Logic
Benchtop instruments and rack-mounted test equipment use the A42MX16-1PQG100 for timing sequencers, trigger logic, and interface glue logic that must remain fixed and deterministic across production units. The one-time-programmable nature guarantees identical configuration in every shipped unit - no firmware corruption risk in the field. JTAG boundary scan (IEEE 1149.1) enables full board interconnect testing during instrument calibration, and the 5.0 V I/O directly interfaces the legacy backplane and front-panel signaling common in long-lived instrument platforms.

Key Differentiators
- 24K gate density in the MX family PQ-100 footprint (vs A42MX09-2PQG100I)
- Non-volatile antifuse configuration with no boot PROM (vs A42MX16-PQ100)
- Military temperature variant available on same die (vs A42MX16-1PQG100M)
Design Notes
The MX family operates from a single 5.0 V supply. Decouple each VDD pin of the PQ-100 package with 0.1 uF ceramic capacitors placed within 5 mm of the pin, plus bulk 10 uF tantalum per supply rail. Current consumption depends on toggling activity; obtain dynamic current estimates from the Microchip Designer tool power calculator rather than assuming worst-case datasheet numbers, and size the 5V regulator with margin for simultaneous output switching.
This is a one-time-programmable antifuse FPGA - a programmed device can never be reprogrammed. Complete full functional simulation and static timing analysis in Microchip Libero/Designer before releasing a design to Silicon Sculptor programming. Do not treat the -1 speed grade as interchangeable with -2 parts in timing-critical paths; check AC timing tables in datasheet DS2136 for your actual operating conditions.
With 83 5.0 V CMOS I/O, ground bounce can be significant when many outputs switch simultaneously. Assign high-toggle-rate signals near GND pins, use the MX family's programmable output slew-rate options to slow non-critical edges, and maintain a solid, unbroken ground plane under the PQFP. Follow Microchip MX application notes for recommended max simultaneous switching output counts per ground pin.
Compliance Information
The G suffix in A42MX16-1PQG100 denotes lead-free packaging per distributor listings (PCB Electronics: 'LEAD FREE'). RoHS/REACH certificates should be requested from Microchip directly.
