A42MX24-TQG176 概要
An antifuse FPGA is a field-programmable gate array whose programmable interconnect elements are open circuits that permanently close when programmed. Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices such as the 42MX family retain their configuration through power cycles, require no external configuration PROM, and exhibit no configuration readback - making them inherently resistant to bitstream cloning and radiation-induced configuration upsets.
Key features include a 5.0V-tolerant architecture, a sea-of-modules fabric combining C-modules (combinational logic) and S-modules (sequential logic), plus D-modules around the device periphery that provide fast, wide-input AND decode functions similar to CPLD architectures. The A42MX24 provides 912 logic cells, supporting legacy PLD integration into a single low-cost device per Microchip product documentation.
Technically, the MX family is built on a 0.45-micron antifuse CMOS process, achieving deterministic interconnect delays ideal for safety- and reliability-focused designs. Because programming is permanent, timing does not vary with reconfiguration, simplifying signal-integrity analysis in industrial control and avionics heritage platforms.
Typical applications include glue logic consolidation, legacy PLD and ASIC integration, industrial automation control, and MIL/aerospace heritage system sustenance where firmware-update capability is not required and configuration security matters.
Design consideration: since the device is one-time-programmable, thoroughly verify the design in simulation and, if possible, prototype on a larger MX device before committing to production programming.

主な用途
A42MX24-TQG176 の用途: 6 件s: Legacy PLD Consolidation, Industrial Automation Control, ASIC Prototyping and Bridging, Aerospace Heritage Sustenance, Security-Sensitive Logic, Telecommunications Interface Cards.
Legacy PLD Consolidation
The A42MX24-TQG176 is purpose-built for consolidating multiple legacy PLDs, PALs, and GALs into one 36K-gate antifuse device. Its flexible 5.0V architecture per Microchip directly supports 5V legacy I/O, eliminating level translators. With 912 logic cells and D-module wide-decode periphery, it absorbs decode logic and state machines that older SPLDs handled. The one-time-programmable fabric locks in the consolidated design without external configuration memory, matching the non-volatile behavior of the devices it replaces.
おすすめ
Industrial Automation Control
In industrial automation, the A42MX24-TQG176 provides deterministic, configuration-immune control logic for motor sequencing, interlocks, and I/O expansion. The antifuse fabric cannot lose configuration from power glitches or SEUs, a benefit SRAM FPGAs cannot match without configuration scrubbing. 3.3V/5V I/O connects directly to legacy PLC signal levels. With 150 user I/O in TQFP-176, one device replaces several glue-logic chips, reducing BOM cost in high-volume factory equipment where firmware update capability is not required.
おすすめ
ASIC Prototyping and Bridging
As a single-chip ASIC alternative, the A42MX24-TQG176 serves as low-volume ASIC bridging or prototyping silicon for gate-array-class designs up to 36K gates. The C-module/S-module sea-of-modules fabric maps ASIC-synthesized netlists efficiently, and antifuse delays are deterministic, simplifying timing sign-off versus SRAM FPGA reconfiguration variability. For bridge ASICs in obsolete-component emulation, permanent programming protects proprietary netlists since there is no bitstream to read back, an advantage over SRAM-based competitors.
おすすめ
Aerospace Heritage Sustenance
Heritage avionics and defense programs designed around Actel MX devices continue to require authentic A42MX24 silicon for lifetime sustenance. The antifuse architecture's inherent tolerance to configuration upsets and absence of configuration readback made MX a long-standing choice in such programs. The TQG176M variant with M-suffix screening supports extended-environment needs. With 36K gates and 150 I/O, board-level drop-in replacement restores supply for existing layouts with zero redesign risk when the exact grade suffix is matched.
おすすめ
Security-Sensitive Logic
Because antifuse programming is permanent and the A42MX24 has no configuration bitstream to read back or intercept, it suits designs where IP protection matters: cryptographic glue logic, authentication decoders, and proprietary interface translation. Unlike SRAM FPGAs that load configuration from external flash at power-up (an interception point), the MX device powers up fully configured with zero boot latency - also valuable for time-critical startup in industrial and communications equipment requiring instant-on behavior.
おすすめ
Telecommunications Interface Cards
Telecom line cards and backplane adapters use the A42MX24-TQG176 for protocol glue, address decoding, and bus bridging. D-modules provide fast wide-input AND decode similar to CPLD structures, well matched to chip-select and address-map logic at the card edge. The 3.3V/5V I/O tolerates mixed-voltage backplanes common in legacy telecom racks. Deterministic antifuse timing ensures stable setup/hold across production units without configuration-dependent variation, easing qualification of high-volume card manufacturing runs.

主な差別化要因
- Highest 42MX density in TQFP-176 footprint （vs A42MX16-2TQG176)
- Configuration security with zero boot time （vs SRAM FPGAs (e.g., Xilinx XC4000-class))
- 5.0V-tolerant architecture （vs A42MX09-TQG176A)
設計ノート
The A42MX24 is one-time programmable - there is no field update path. Complete gate-level timing simulation and, ideally, program a sample device for hardware validation before committing production quantities. If capacity is uncertain, prototype on A42MX36 silicon and scale down, or design the board to also accept A42MX16/A42MX09 TQFP-176 devices since the family shares the footprint.
Follow the MX family datasheet power guidelines: decouple VCCA and VCCI rails with 0.1uF ceramic capacitors at multiple package corners plus bulk capacitance per rail. The TQFP-176 0.5mm-pitch leads require careful land-pattern compliance; use the mechanical drawing in the 40MX/42MX datasheet. Because no configuration device is needed, reserve no board space for a PROM - a simplification versus SRAM FPGA layouts.
The 5V-tolerant I/O simplifies interfacing to legacy TTL/5V CMOS, but observe per-bank current limits from the datasheet DC characteristics when driving many outputs simultaneously. Antifuse interconnect delays are deterministic and do not change after programming; still, run static timing analysis in Libero/Designer with worst-case commercial or industrial corners matching the ordered grade suffix (-1, -2, -3 or base).
