Typical Applications
A42MX24-1PQG160 is suitable for 6 applications: Legacy 5V Industrial Control, PLD Consolidation / Single-Chip ASIC Alternative, Communications Backplane Glue Logic, Motor Drive and Control Interface Logic, Test and Measurement Instrumentation, Aviation, Military and High-Reliability Legacy Systems.
Legacy 5V Industrial Control
The A42MX24-1PQG160's native 5.0V-tolerant architecture makes it a natural fit for industrial controllers still running 5V TTL/CMOS logic rails, where modern 1.0-3.3V FPGAs would require level shifters on every I/O. Its 36K gates and 125 user I/O consolidate discrete PLDs, counters, and glue logic into one device. Placed directly on the 5V backplane with standard PQFP-160 footprints, it eliminates bus-transceiver mismatch risk and reduces board area while keeping proven 5V noise margins intact.
Recommended
PLD Consolidation / Single-Chip ASIC Alternative
Microchip positions MX FPGAs as a reliable single-chip ASIC alternative for high-volume production. A typical redesign integrates several 22V10-class CPLDs, PALs, and glue logic into the A42MX24's 912 CLBs, cutting component count and programming variants. Because the MX family offers a 5.0V flexible architecture, existing 5V board power trees are preserved. Using D-module wide-decode resources, address decoding functions that span multiple legacy devices execute in one fast path, shortening system development cycles.
Recommended
Communications Backplane Glue Logic
In telecom and datacom line cards, the A42MX24-1PQG160 performs address decoding, bus arbitration, and status-register functions between processors and backplane transceivers. The 125 I/O provide enough pins for 32-bit data paths plus control, and the -1 speed grade supports the sub-100 MHz timing typical of legacy backplanes. The 160-pin PQFP gull-wing package simplifies inspection and rework compared with BGA alternatives, an advantage for long-life systems maintained in the field.
Recommended
Motor Drive and Control Interface Logic
Industrial motor controllers use the A42MX24-1PQG160 for PWM generation, quadrature-encoder decoding, and fault-latching logic interfacing 5V gate drivers. The device's predictable 0.45um CMOS timing and wide 5V I/O thresholds interface directly with gate-driver and optocoupler circuitry. With 36K gates, a full three-phase control state machine plus protection interlocks fit comfortably, and the D-modules accelerate the wide fault-input AND functions needed for fast shutdown paths.
Recommended
Test and Measurement Instrumentation
Bench instruments and automated test fixtures employ the A42MX24-1PQG160 for timing generation, pattern capture, and interface adaptation. The MX architecture's deterministic routing simplifies timing closure for fixed stimulus patterns, and the 5.0V I/O withstand common fixture over-voltages better than modern low-voltage FPGAs. The PQFP-160 package allows socketed prototypes for rapid iteration. Designers typically implement pattern generators, frequency dividers, and handshaking state machines across the 912 CLBs.
Recommended
Aviation, Military and High-Reliability Legacy Systems
The MX family extends into military and space-grade variants (A42MX24-PQG160A and M-suffix screenings), making the commercial A42MX24-1PQG160 relevant for maintaining ground-support and legacy defense platforms. Long availability cycles and the stable 0.45um process support programs requiring multi-decade component supply. Using the same footprint across commercial, industrial, and military-grade PQFP-160 members lets one PCB layout cover multiple program temperature and screening requirements.

Key Differentiators
- Lowest-cost speed grade within the same die (vs A42MX24-3PQG160I)
- Highest logic capacity sharing the PQFP-160 footprint (vs A42MX16-2PQG160)
- Native 5.0V I/O architecture (vs Modern low-voltage FPGAs (e.g., PolarFire))
Design Notes
Power the A42MX24-1PQG160 from a clean 5.0V rail (3.3V options exist in the MX family architecture per Microchip). Decouple all VCC/VPP pins with 0.1uF ceramic capacitors placed within 5 mm of each supply pin, plus bulk 10uF at the board level. Follow the 40MX/42MX datasheet (DS2136) power-up sequencing requirements to avoid configuration corruption at startup.
The 160-pin PQFP has 0.65 mm-pitch gull-wing leads requiring careful solder-paste stencil design; use NSMD pads and a 1:1 aperture. Keep configuration and JTAG traces short and away from high-current motor or relay lines. Provide a solid ground plane under the device to return I/O switching currents and maintain the MX family's noise margins in 5V systems.
Do not mix speed grades within a system expectation: a design meeting timing on the -3 grade may fail on the -1 grade; run static timing analysis in Libero SoC at your actual grade. Also confirm lifecycle expectations - the 0.45um MX family serves legacy markets, so lock in long-term supply agreements before committing new production volumes.
Compliance Information
Distributor listing (PCB Electronics Supply Chain) identifies the part as LEAD FREE. Formal RoHS/REACH certificates should be confirmed via Microchip's product page for A42MX24.
