A42MX16-3PQG100 概要
An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that designers configure after manufacturing. Within the programmable logic hierarchy - FPGA -> programmable logic device -> digital integrated circuit - the MX family is unique because it uses antifuse programming technology, which is one-time programmable (OTP). Unlike SRAM-based FPGAs, antifuse devices retain their configuration permanently, require no external configuration memory, and provide inherent design security against bitstream extraction.
Key features include 608 configurable logic cells, a flexible 5.0V-tolerant architecture, and low power consumption typical of antifuse technology. The speed grade -3 designation indicates the fastest commercial timing tier within the A42MX16 family, making it suitable for glue logic consolidation and state machines with tight timing. Because configuration is stored in antifuse elements, the device is immune to configuration readback attacks, a key differentiator versus SRAM FPGA competitors.
The MX family positions itself as a reliable, single-chip ASIC alternative, allowing legacy PLD/CPLD integration into one low-cost, high-volume device. Typical applications include industrial control, aerospace and defense systems needing design security, telecommunications line cards, and legacy 5V system obsolescence bridging.
Design consideration: antifuse FPGAs are one-time programmable - functional changes require a new device, so verify the design fully in simulation or with a development device before committing production units. Pricing as of 2026-08-30 from distributor data.

主な用途
A42MX16-3PQG100 の用途: 6 件s: 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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
