A42MX24-3PLG84I Обзор
A field programmable gate array (FPGA) is an integrated circuit that engineers configure after manufacturing to implement custom digital logic. The MX family sits within the broader taxonomy of FPGA > programmable logic device > semiconductor, and unlike SRAM-based FPGAs, its antifuse-based programming is non-volatile and radiation-tolerant by construction, requiring no configuration device at power-up.
Key features include 36K system gates with D-modules arranged around the device periphery providing fast, wide-input AND decode functions similar to CPLD architectures, an efficient flexible 5.0V-tolerant architecture, and legacy PLD integration on a single low-cost device. Speed grade -3 denotes the fastest commercial/industrial bin in the family. The 84-PLCC (29.31x29.31 mm) surface-mount package offers through-hole-like mechanical robustness favored in aerospace, industrial, and defense retrofits.
Architecturally, the device combines combinatorial R-modules, sequential C-modules, and wide-decode D-modules, enabling glue logic consolidation, bus interfacing, and state-machine implementation with deterministic timing. Microsemi (now Microchip) positioned MX as a high-volume ASIC replacement platform.
Typical applications include legacy system obsolescence redesign, industrial control glue logic, military/aerospace interface bridging, and communications backplane control.
Design consideration: verify power sequencing of the 3.3V and 5.0V rails and confirm last-time-buy status against your lifecycle plan, as the MX family is in end-of-life transition. Prices as of 2026-08-30.

Типичное применение
A42MX24-3PLG84I подходит для 6 применениеs: Legacy System Obsolescence Redesign, Aerospace and Defense Interface Logic, Industrial Control Glue Logic, Communications Backplane Control, Test and Measurement Fixture Logic, ASIC Prototyping and Low-Volume Bridge.
Legacy System Obsolescence Redesign
The MX family is Microsemi's designated platform for integrating legacy PLDs and discontinued logic into a single chip. With 36K gates, dual 3.3V/5V operation, and the mechanically robust 84-PLCC package, the A42MX24-3PLG84I can absorb multiple 22V10-class PLDs, bus transceivers' glue logic, and address decoders while remaining pin-compatible with older MX-based boards. Its antifuse programming is non-volatile, so retrofitted systems power up instantly without configuration devices - a key requirement when replacing components in equipment that must boot unattended.
Рекомендуется
Aerospace and Defense Interface Logic
Actel/Microsemi antifuse FPGAs have a long heritage in defense and aerospace programs because their antifuse interconnect resists configuration upsets and needs no external boot flash. The industrial-temperature A42MX24-3PLG84I provides 36K gates of deterministic-logic for bus interface bridging, discrete I/O conditioning, and wide-decode functions via D-modules that emulate CPLD-style fast AND arrays. The 5V-tolerant architecture directly interfaces MIL-style 5V signaling, and the PLCC J-lead package withstands vibration better than fine-pitch QFP alternatives.
Рекомендуется
Industrial Control Glue Logic
In industrial controllers, PLC I/O cards, and motor-drive backplanes, the A42MX24-3PLG84I consolidates address decoding, interrupt arbitration, and status multiplexing that previously occupied several SSI/MSI devices. The dual 3.3V/5V supply ranges (3V~3.6V and 4.75V~5.25V) let it sit directly on legacy 5V control buses without level translators, while 912 logic cells and D-module wide-decode deliver fast, deterministic decode times. Its instant-on antifuse configuration eliminates boot-delay concerns in machines that must respond at power-up.
Рекомендуется
Communications Backplane Control
Telecom and datacom line cards historically used MX FPGAs for backplane handshaking, board identification, and hot-swap control sequencing. The A42MX24-3PLG84I's 72 user I/O and 36K gates implement JTAG boundary-scan-friendly control fabrics with wide-input AND decode for address and slot identification. Because the antifuse fabric is write-once and non-volatile, line cards recover instantly after power cycles or shelf storage - unlike SRAM FPGAs that need reconfiguration - reducing field MTTR in carrier-grade equipment.
Рекомендуется
Test and Measurement Fixture Logic
Bed-of-nails fixtures and automated test equipment benefit from the A42MX24-3PLG84I as a reprogrammable (one-time) but re-manufacturable decode resource: fixtures can be rebuilt with fresh devices per test revision. Wide-decode D-modules give fast channel-select AND functions with predictable propagation, important for timing-accurate stimulus routing. The 5V-tolerant I/O interfaces directly with legacy TTL-level test signals, and the PLCC socket-compatible package lets fixtures swap devices without soldering during calibration.
Рекомендуется
ASIC Prototyping and Low-Volume Bridge
Microchip markets MX as a reliable, single-chip ASIC alternative for high-volume, low-cost integration. Before ASIC tape-out, the A42MX24-3PLG84I prototypes control-plane logic of approximately 36K gates; the same netlist maps to production MX devices for bridge production. The 0.45 um antifuse process offers gate-level timing close to the original ASIC library targets, and the -3 speed grade minimizes timing closure risk. For volumes too low for ASIC economics, MX becomes the permanent production silicon itself.

Заметки по проектированию
The A42MX24-3PLG84I requires dual supplies: 3.3V (3V~3.6V) for core/output and 5V (4.75V~5.25V) per the 40MX/42MX datasheet DS2316. Verify rail sequencing against your board's power tree; add 0.1uF ceramic decoupling per supply pin plus bulk 10uF at the device. The 5V tolerance is a key legacy advantage, but do not mix 5V inputs on a 3.3V-only bank - consult the datasheet I/O configuration tables.
This part is antifuse-programmed and one-time programmable: an incorrect bitstream permanently consumes the device. Always validate the design fully in simulation (Libero/Microchip design tools) and, if possible, on a commercial-temperature A42MX24-3PLG84 before programming industrial units. Also confirm timing closure at speed grade -3; if slack is thin, the -2 or -1 grade parts will not meet timing as drop-ins.
The 84-PLCC J-lead package is socket-compatible, which simplifies field replacement but adds contact inductance; keep JTAG TCK lines short and series-terminate if the chain exceeds a few inches. Provide a solid ground plane under the PLCC and follow the DS2316 PLG84 mechanical drawing (29.31x29.31 mm) for land pattern dimensions to ensure socket compatibility.
