A42MX16-PQG100A Visão geral
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements digital circuits through a fabric of configurable logic blocks, flip-flops, and routing resources. Unlike SRAM-based FPGAs, the MX family uses antifuse programming technology, which is one-time programmable (OTP): the configuration becomes permanent at power-up with no boot time and no external configuration memory required.
Key features include the flexible 5.0V architecture that directly interfaces with legacy 5V TTL and 5V PLD logic, low power consumption, inherent design security (no bitstream to steal), and the single-chip ASIC-alternative positioning Microchip promotes for high-volume designs. The MX family is an ideal platform for integrating legacy PLDs and glue logic into a single low-cost device, and its antifuse fabric is immune to configuration-upset issues that affect SRAM FPGAs in radiation-prone environments.
Architecturally, the 42MX device combines combinational modules and sequential modules arranged in a sea-of-modules fabric with dedicated routed clocks. Logic capacity is expressed as 24K system gates with 608 usable cells, and the device achieves 153 MHz toggle performance on a 0.45 um CMOS process. Design entry is performed with Microchip Libero SoC design tools targeting the MX families.
Typical applications include legacy 5V system redesigns, industrial control, defense and aerospace programmable glue logic, automotive control modules, and bridging between microprocessors and peripheral logic where 5V tolerance and instant-on operation matter.
Design consideration: because the device is one-time programmable, verify the design fully in simulation and, where practical, prototype on a larger-density MX device before committing to production programming. Pricing referenced as of 2026-08-30 from distributor data.

Aplicações típicas
A42MX16-PQG100A é adequado para 6 aplicaçãos: Legacy 5V System Redesign, Automotive Control Modules, Industrial Glue Logic Consolidation, Defense and Aerospace Programmable Logic, ASIC Prototyping and Bridge Logic, Secure Embedded Controllers.
Legacy 5V System Redesign
The A42MX16-PQG100A's native 5.0V architecture directly interfaces with legacy TTL, 5V CMOS, and older PLD logic without level translators. Its 83 user I/O and 24K gates absorb several discrete glue-logic devices into one antifuse FPGA, while the one-time-programmable fabric powers up instantly with no configuration device - a key benefit when refreshing boards that must keep 5V signaling. Sourcing gets simpler too: MX is a high-volume, long-lifecycle platform designed explicitly for consolidating legacy PLDs, reducing BOM count and obsolescence risk in mature industrial products.
Recomendado
Automotive Control Modules
The A suffix on A42MX16-PQG100A denotes automotive-grade screening, making it appropriate for in-vehicle controllers that need deterministic, instant-on logic. Antifuse configuration cannot be corrupted by power glitches, and the permanent fabric removes external configuration memory from the reliability chain. With 153 MHz capability, the device handles motor sequencing, sensor interface decoding, and module interconnect bridging at 5V automotive signaling levels. Design teams should validate temperature-range and screening documentation from Microchip for the specific build standard required by their automotive qualification program.
Recomendado
Industrial Glue Logic Consolidation
Factory automation and process-control boards frequently carry multiple PLDs, PALs, and bus-interface devices. The A42MX16's 608 cells and flexible fabric integrate address decoders, state machines, interrupt controllers, and bus bridges into a single 100-pin PQFP, cutting board area and assembly cost. The 5V I/O tolerance simplifies interfacing with legacy industrial sensors and actuators still operating at TTL levels. Because the design is programmed once and locked, field-updated firmware risk and configuration corruption - concerns with SRAM FPGAs on electrically noisy factory floors - are eliminated by the antifuse technology.
Recomendado
Defense and Aerospace Programmable Logic
Antifuse MX FPGAs are favored in defense and aerospace for radiation-tolerance characteristics and configuration immunity: the permanent interconnect cannot be upset by single events the way SRAM configuration bits can. The MX family extends to military-screened orderable variants (for example A42MX16-1PQG100M in the same package), letting teams reuse one PCB layout across commercial, industrial, and military screening levels. The device suits command decoders, telemetry formatting, and interface adaptation where 5V heritage signaling and instant-on, configuration-free startup are required at power application.
Recomendado
ASIC Prototyping and Bridge Logic
Microchip positions the MX family as a reliable single-chip ASIC alternative for high volumes. Before committing to an ASIC, engineers can implement the design in an A42MX16 - the 24K-gate capacity suits controller blocks, protocol adapters, and data-path glue logic - and validate it in-system at full 5V operating conditions. If volumes stay below ASIC economic thresholds, the FPGA itself can ship in production, avoiding mask costs entirely. The 153 MHz fabric performance covers many microprocessor peripheral and memory-interface bridging tasks on legacy 5V bus systems.
Recomendado
Secure Embedded Controllers
Where intellectual-property protection matters, the A42MX16-PQG100A's antifuse technology is a strong security asset: there is no configuration bitstream stored externally or readable from the device, so reverse engineering the implemented logic is exceptionally difficult compared with SRAM FPGAs that load bitstreams at boot. This suits secure access terminals, encoders, authentication bridges, and proprietary control algorithms. The instant-on behavior also means the secure logic is active before any external configuration process could be attacked, closing a window that SRAM-based designs must otherwise protect against.

Notas de projeto
The 42MX family operates from a single 5.0V rail. Verify the datasheet DS2316 for per-rail current consumption at your toggle rate; antifuse FPGAs draw dynamic current proportional to clock frequency and switching activity. Decouple VDD with at least 0.1uF per power pin plus bulk capacitance near the device. Because the device is instant-on, ensure the 5V rail ramps monotonically - there is no configuration supervisor to gate logic activity during brownouts.
The 100-pin PQFP has leads on 0.635 mm pitch on all four sides. Keep trace lengths from the dedicated clock input short and route away from switching I/O to minimize skew and jitter. Boundary-scan TDI/TDO/TMS/TCK pins are chained per the DS2316 datasheet - bring them to a header for production programming and ICT access. The PQFP body requires the full footprint land pattern per Microchip's recommended layout.
The A42MX16 is one-time programmable: a logic error cannot be fixed by reflashing, only by scrapping the part. Fully simulate in Libero SoC, run timing analysis at your speed grade (-1, -3), and prototype on a lower-cost variant or larger MX device before committing production units. Also confirm the correct speed grade suffix when ordering - PQG100, -1PQG100, and -3PQG100 differ in timing only.
