A42MX16-VQG100I 概要
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements custom digital circuits after manufacturing. The MX family uses Actel antifuse technology, a one-time-programmable interconnect that is inherently non-volatile, low-power, and resistant to configuration upset - making MX devices a reliable, single-chip ASIC alternative for high-volume designs and legacy PLD consolidation.
Key features include the cost-effective 5.0V architecture, single-chip operation without external configuration devices, industrial temperature range (-40C to +85C) denoted by the -I suffix, and secure antifuse programming that leaves no bitstream to read back. With 24K system gates, the device integrates glue logic, bus interfaces, and state machines that previously required multiple discrete PLDs.
Technically, the 42MX architecture combines combinatorial logic modules with sequential modules, routing through low-resistance antifuse elements. This yields deterministic timing, low static power, and immunity to configuration errors compared to SRAM FPGAs. The trade-off is one-time programmability: design changes require a new device rather than a re-flash.
Typical applications include industrial control systems, military/defense upgrades, legacy ASIC/PLD integration, 5V bus interfacing, and high-volume embedded controllers where non-volatile, tamper-resistant logic is required. Designers should verify design freeze before programming, as antifuse devices cannot be reworked in the field. Use Microchip Libero SoC for design entry and programming file generation.

主な用途
A42MX16-VQG100I の用途: 6 件s: Industrial Control and Automation, Legacy PLD and ASIC Integration, Military and Defense Upgrades, 5V Bus Interface and Glue Logic, Secure and Tamper-Resistant Embedded Logic, Test and Measurement Instrumentation.
Industrial Control and Automation
The A42MX16-VQG100I fits industrial control because its 24K gates and 83 user I/Os consolidate PLC glue logic, motor control state machines, and sensor interfaces that previously occupied multiple PLDs. Its 5V core with 3.3V/5V I/O tolerance interfaces directly with 24V-system front-end logic and legacy TTL backplanes without level shifting. As an antifuse device, it powers up instantly in the correct configuration with no boot device - critical for deterministic startup in factory automation. Industrial -40C to +85C rating covers unconditioned cabinets.
おすすめ
Legacy PLD and ASIC Integration
The MX family is explicitly positioned by Microchip as a single-chip ASIC alternative for integrating legacy PLDs. The A42MX16-VQG100I provides 24K system gates and 608 cells - enough for multiple 22V10-class PLDs plus glue logic on one die. Antifuse one-time programming means the consolidated design cannot be read back or corrupted, protecting legacy IP in long-lifecycle products. Using Libero SoC, designers migrate aging schematics once, then lock the netlist into silicon for high-volume production with stable, deterministic timing.
おすすめ
Military and Defense Upgrades
The A42MX16-VQG100M variant shares the same 100-pin VQFP footprint with military screening, letting defense upgrade programs qualify one board across commercial and screened builds. The standard -I device at -40C to +85C suits ground-based systems, while the 0.45um antifuse process resists configuration upset that affects SRAM FPGAs under radiation - a documented MX family advantage. With no external configuration flash, there is no boot-time vulnerability window. The 5V I/O directly drives legacy MIL-STD logic families common in retrofitted platforms.
おすすめ
5V Bus Interface and Glue Logic
Modern FPGAs with 1.2-1.8V cores cannot tolerate 5V signaling, but the A42MX16-VQG100I is built on a 5.0V architecture with 3.3V/5V I/O, so it connects directly to 5V TTL buses, ISA-style backplanes, and peripheral controllers. Its 83 I/Os handle wide data buses, address decoding, bus arbitration, and handshaking in one chip. Deterministic antifuse routing keeps propagation delays fixed, simplifying bus timing analysis. Designers typically combine it with bus transceivers for extended fan-out and ESD margin.
おすすめ
Secure and Tamper-Resistant Embedded Logic
Antifuse technology leaves no readable configuration bitstream, unlike SRAM FPGAs whose bitstream can be intercepted or cloned. For products protecting proprietary algorithms, encryption keys, or licensing logic, the A42MX16-VQG100I stores the design permanently in silicon with no readback path. Instant-on behavior also removes cold-boot attack windows. With 24K gates, engineers fit small AES cores, authentication engines, or anti-counterfeit checkers alongside application logic. This makes MX a cost-effective option where Microchip's security-oriented families are overkill and volume is high.
おすすめ
Test and Measurement Instrumentation
In bench and ATE instruments, the A42MX16-VQG100I implements trigger logic, counter/timers, bus decoders, and stimulus sequencers with cycle-accurate deterministic timing - a benefit of fixed antifuse routing delays. The 103 MHz/172 MHz toggle capability supports fast event capture, and 83 I/Os connect to front-end MUXes, comparators, and display drivers on a single device. Non-volatile configuration means instruments are ready the moment power is applied. Industrial temperature rating suits rack-mounted environments without forced-air cooling restrictions.

主な差別化要因
- Non-volatile antifuse configuration in a single chip （vs A42MX16-1VQG100I)

- Same footprint across screening grades （vs A42MX16-VQG100M)
設計ノート
The A42MX16 is one-time programmable antifuse silicon - once programmed, the design cannot be changed or read back. Freeze your design after full functional simulation, static timing analysis, and (where possible) prototype validation on the same device type. Ordering spare programmed units for each design revision is standard practice for MX-based production.
The 42MX family operates on a 5.0V core with 3.3V/5V I/O capability. Provide a clean 5V rail with local 0.1uF ceramic decoupling per supply pin group plus 10uF bulk capacitance. Antifuse FPGAs have low static current, but dynamic I/O switching current on 83 outputs can be significant - verify ground bounce with simultaneous-switching analysis when driving wide 5V buses.
The 100-pin VQFP has 0.5mm lead pitch requiring fine-pitch soldering; use a 0.5mm-pitch footprint per IPC-7351 conventions and inspect with magnification or X-ray. Route all VQFP supply pairs with short, wide traces. Since all A42MX16 VQG100 speed grades share this footprint, design the board once and accommodate any grade for procurement flexibility.
