Typical Applications
A42MX24-1PQG160M is suitable for 6 applications: Glue Logic Consolidation, Industrial Control Systems, ASIC Prototyping and Bridge Logic, Aerospace and Defense (SEU-Immune Configuration), Legacy 5V System Integration, Secure Embedded Systems.
Glue Logic Consolidation
The A42MX24-1PQG160M excels at replacing multiple discrete SSI/MSI logic chips and legacy PLDs with a single 36,000-gate antifuse device. Its 912 logic cells and D-module wide-decode circuitry implement fast, wide-input AND functions similar to CPLD architectures, while 125 user I/Os handle diverse board-level interconnect. Because configuration is non-volatile antifuse, the consolidated logic is live at power-up with zero boot delay - critical for systems that must act immediately on power application. The 3.3V/5.0V dual-voltage multiPlex I/O eases interfacing with both legacy 5V and modern 3.3V board regions.
Recommended
Industrial Control Systems
Industrial controllers benefit from the A42MX24's instant-on, SEU-immune antifuse configuration and wide 3.3V/5.0V operating architecture. In PLC I/O modules and motor-control interface boards, the device's 125 mixed-voltage I/Os directly bridge legacy 5V sensors to 3.3V microcontroller domains without level shifters. The -1 speed grade at low cost suits high-volume control logic, while inherent bitstream security protects proprietary control algorithms from cloning. Designers should verify thermal and timing closure in Libero SoC, as the one-time-programmable nature demands thorough pre-production simulation.
Recommended
ASIC Prototyping and Bridge Logic
As a reliable single-chip ASIC alternative, the A42MX24 serves ASIC prototyping, low-volume ASIC replacement, and bus-bridge logic. Its 0.45um CMOS antifuse process delivers deterministic timing comparable to hard-wired logic, and the 36K-gate capacity accommodates moderate protocol bridges and address decoders. The multiPlex I/O architecture supports programmable PCI interfaces at both 5.0V and 3.3V signaling. Unlike SRAM FPGAs, there is no configuration readback path, so designs shipping to customers retain full IP confidentiality throughout the product lifecycle.
Recommended
Aerospace and Defense (SEU-Immune Configuration)
Antifuse configuration makes the 42MX family attractive for harsh-environment and defense applications where configuration upsets from radiation are unacceptable. The A42MX24's configuration data resides in physical antifuse elements that cannot flip like SRAM cells, eliminating configuration SEU failure modes entirely - a major advantage over SRAM FPGAs needing external mitigation. With instant-on behavior, the device is ready before supervisory circuits complete power-good assertions. Pair with industrial-temperature speed grades such as the -2 or -3 I variants for extended temperature operation.
Recommended
Legacy 5V System Integration
Many deployed industrial and telecom boards still run 5.0V backplanes. The A42MX24-1PQG160M's efficient 5.0V architecture and multiPlex I/Os allow direct connection to 5V TTL signaling while also supporting 3.3V banks, letting designers integrate modern logic into legacy systems without bus-violation risk. The 160-pin PQFP has gull-wing leads compatible with standard SMT assembly, and its non-volatile configuration means no firmware image must be stored on aging configuration PROMs - removing a common field-failure point in legacy equipment service and repair.
Recommended
Secure Embedded Systems
For products where reverse engineering is a business risk - payment terminals, licensed peripherals, proprietary industrial equipment - the A42MX24 offers inherent design security. Because the antifuse interconnect cannot be read back and the bitstream never exists outside programming equipment, attackers cannot clone functionality as they can with SRAM FPGAs. The 912 cells implement authentication logic, custom bus functions, or cipher accelerators. Combine with an external secure MCU for challenge-response schemes; the FPGA holds the unclonable fused logic while the MCU manages transactions.

Key Differentiators
- Inherent configuration security and SEU immunity (vs SRAM-based FPGAs (e.g., Xilinx Spartan family))
- Instant-on, non-volatile operation (vs A42MX24-2PQG160I)
- Dual 3.3V/5.0V mixed-voltage I/O (vs A42MX09-1PQG160I)
Design Notes
The 42MX architecture operates from 5.0V with 3.3V support via multiPlex I/O. Decouple both rails with 0.1uF ceramic capacitors placed within 5 mm of the PQFP supply pins, plus 10uF bulk capacitance per rail. Antifuse devices draw no configuration current at power-up, but I/O switching current can spike - size the 5V regulator for simultaneous I/O switching worst case rather than average current.
The A42MX24 is one-time programmable: a design revision requires a physically new device. Complete full functional simulation and static timing analysis in Microchip Libero SoC before programming production units, and hold a small programmed-spare inventory. Verify the '-1' speed grade meets your timing at your operating temperature - faster -2/-3 grades exist in the same 160-PQFP if margin is insufficient.
The 160-pin PQFP gull-wing package needs careful land-pattern design per the DS2316 mechanical drawing to avoid solder bridging on 0.65mm-class pitch. Support unused I/O as defined in the Libero pin report - do not leave them floating. The M-suffix tray packaging requires Moisture Sensitivity handling per the bag label before reflow; check MSL rating and floor-life.
