A42MX16-1PQG100M 概要
An FPGA (field-programmable gate array) is a semiconductor device containing programmable logic blocks and interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), the MX family positions itself as a reliable, single-chip ASIC alternative for high-volume, cost-sensitive systems, and is an ideal platform for consolidating legacy PLDs into a single low-cost device.
Key features include the flexible 5.0V architecture inherited from the Actel/Microsemi antifuse-based design philosophy, dual 3.3V/5V supply compatibility for mixed-voltage legacy systems, and 83 programmable I/O for glue logic, bus interfacing, and control functions. The MX family provides designers with a dependable migration path from multiple discrete PLDs to one programmable device, reducing board area, BOM cost, and inventory complexity.
Technically, the A42MX16 uses the MX routing architecture with segmented interconnect, configured once at programming time rather than via volatile SRAM, giving non-volatile, power-on-ready operation without an external configuration ROM. Design entry and programming flow through Microchip (Microsemi) Libero SoC tools, with back-annotation compatible with major simulators and cross-probing via the Silicon Explorer II verification tool per datasheet DS2136 (40MX and 42MX FPGA Families).
Typical applications include legacy 5V industrial control consolidation, military/aerospace system upgrades (the M suffix designates a screened/military-grade variant), telecommunications line cards, and obsolescence-driven redesigns where a dependable, single-chip ASIC alternative is required.
Design consideration: the 5V-tolerant dual-supply architecture is the primary reason to select this part over modern 3.3V/1.8V FPGAs - verify your I/O voltage domains and programming toolchain availability before committing to new designs.

主な用途
A42MX16-1PQG100M の用途: 6 件s: Military and Aerospace System Upgrades, Legacy 5V Industrial Control Consolidation, PLD Obsolescence Redesign, Telecommunications Line Cards, Test and Measurement Fixtures, Power and Sequencing Glue Logic in Power Supplies.
Military and Aerospace System Upgrades
The A42MX16-1PQG100M carries the M suffix denoting military screening, making it a primary choice for upgrading legacy military avionics, ground vehicles, and space-adjacent ground equipment. The MX non-volatile architecture powers up instantly without an external configuration PROM, a significant reliability advantage in mission-critical systems. With 24K gates and 83 user I/O at 5V-tolerant levels, it consolidates obsolete TTL/PLD glue logic into a single screened device. Engineering teams use Libero SoC to re-verify existing bitstreams; the fixed one-time-programmed configuration also resists configuration-upset concerns relevant to defense platforms.
おすすめ
Legacy 5V Industrial Control Consolidation
Many factory automation and process control systems still run 5V buses and TTL-level sensors. The MX family's native 5.0V architecture with 4.5V to 5.5V operation means the A42MX16-1PQG100M interfaces directly with legacy 5V logic without level shifters, reducing component count and failure points. Designers use its 83 I/O to replace multiple 22V10-class PLDs, PALs, and discrete glue logic in PLC I/O cards and motor control boards. Non-volatile one-time configuration removes the boot-time dependency of SRAM FPGAs, and the same-package A42MX16-1PQG100 commercial variant offers the identical function at lower cost for non-screened industrial builds.
おすすめ
PLD Obsolescence Redesign
When EOL notices arrive for legacy PLDs (PAL, GAL, 22V10, older Actel FPGAs), the A42MX16-1PQG100M serves as a consolidation target that absorbs several obsolete devices into one programmable part. Its 24,000 gates and 608 cells comfortably host multiple medium-density PLD functions, and Microchip explicitly positions MX as an ideal platform for integrating legacy PLDs into a single low-cost device. The 100-BQFP with 0.65 mm pitch is hand-assemblable for low-volume maintenance builds. Using Libero SoC, existing ABEL or schematic designs can be re-implemented and verified with Silicon Explorer II cross-probing before release.
おすすめ
Telecommunications Line Cards
Legacy telecom backplanes and line cards commonly use 5V signaling and require deterministic, instantly-on logic for framing, alarm, and control-plane functions. The A42MX16-1PQG100M provides 119 MHz toggle capability and 5V-tolerant I/O that connects directly to legacy backplane transceivers, while its non-volatile configuration ensures line cards become operational immediately at power-up - important for hot-swappable and redundancy schemes. The 83 user I/O cover address/data decode, interrupt aggregation, and status multiplexing. For density upgrades, the same-family A42MX24 parts scale gate count while retaining the MX toolchain and design methodology.
おすすめ
Test and Measurement Fixtures
Production test fixtures and ATE adapter boards benefit from the A42MX16-1PQG100M's combination of 5V-tolerant I/O and fixed one-time programming, which guarantees fixture logic cannot be accidentally altered between test runs. The 83 I/O handle boundary-scan chains, relay matrix control, and DUT interface multiplexing, while 24K gates implement address decoders and handshaking state machines at toggle rates up to 119 MHz. Because configuration is non-volatile, no programming controller or boot flash is needed on the fixture board. Engineering teams can replicate fixtures cheaply using the pin-identical commercial A42MX16-1PQG100 where screening is unnecessary.
おすすめ
Power and Sequencing Glue Logic in Power Supplies
High-reliability power supply and power-distribution boards often need 5V-compatible programmable logic for rail sequencing, fault latching, and supervisory decoding. The A42MX16-1PQG100M operates directly from 4.5V to 5.5V rails, eliminating auxiliary 3.3V supplies, and its deterministic non-volatile configuration ensures sequencing logic is active within microseconds of power application - before SRAM FPGAs would even finish loading configuration. Paired with modern TI power management ICs for regulation, the MX FPGA handles supervisory logic while devices like the TPS548B28 or UCC21521 gate drivers handle the power conversion stages.

主な差別化要因
- Military screening (M suffix) in a plastic 100-BQFP （vs A42MX16-1PQG100)
- Native 5.0V architecture eliminates level shifters （vs A42MX16-2PQG100I)
- Non-volatile configuration vs SRAM FPGA alternatives （vs Modern SRAM FPGAs (e.g., Artix-7))
設計ノート
The A42MX16-1PQG100M supports dual supply operation: 4.5V-5.5V (core/5V I/O) and 3.0V-3.6V. In mixed-voltage designs, decouple each VDD domain with at least 0.1uF ceramic capacitors per pin pair plus a 10uF bulk capacitor. Power-up sequencing between the 3.3V and 5V rails should be verified against the datasheet DS2136 power-up specifications to avoid I/O latch-up during ramp. Because configuration is non-volatile, no configuration power sequencing is required - logic is active as soon as supplies reach valid levels.
The 100-BQFP has a 0.65 mm pitch requiring careful PCB land pattern compliance; use the Microchip package mechanical drawing in DS2136 for exact pad dimensions. For military-screened builds, maintain controlled assembly processes (solder profile, cleanliness per program requirements). Keep clock routing short to the dedicated CLKA/CLKB pins, and provide ground return paths under high-activity I/O banks. The BQFP leads are relatively fragile - handle with ESD-safe vacuum pick during assembly.
Do not confuse A42MX16-1PQG100M (military screened, green package) with A42MX16-1PQ100M (standard lead finish) when procurement drawings specify one suffix - they differ in screening and finish. The MX family is one-time programmed: prototype with the commercial A42MX16-1PQG100 and only move to the M part for production screening, since programming errors on the M part are unrecoverable. Also confirm Libero SoC license availability and Silicon Explorer II access before committing the design flow.
