Typical Applications
A42MX24-F is suitable for 6 applications: Legacy PLD Consolidation, 5V PCI Add-in Cards, Industrial Control and Automation, ASIC Prototyping and Bridge Logic, Transportation and Rugged Systems, Test and Measurement Instrumentation.
Legacy PLD Consolidation
The A42MX24-F is marketed by Microchip as an ideal platform for integrating legacy PLDs into a single, low-cost device. Its 24,000 system gates absorb multiple PAL/GAL/22V10 devices and older Actel 1200XL or 3200DX designs, while the 5.0V architecture directly matches legacy board supply rails. Because the antifuse fabric is non-volatile, the consolidated design powers up instantly with no boot flash. The Microchip migration application note documents package-equivalent paths from 1200XL/3200DX, reducing redesign risk when consolidating mature industrial boards.
Recommended
5V PCI Add-in Cards
Per the Microchip MX datasheet, the MultiPlex I/O structure is fully compliant with the PCI Local Bus Specification version 2.1 and supports programmable PCI at both 5.0V and 3.3V with a low-power mode. The A42MX24-F therefore suits 5V PCI add-in cards for industrial PCs, test instruments, and medical equipment where the host bus is still 5V-tolerant. D-module wide-decode circuitry accelerates address decode and chip-select generation, while the antifuse configuration eliminates the boot-device reliability concerns typical of SRAM FPGAs on plug-in cards.
Recommended
Industrial Control and Automation
Industrial controllers frequently mix 5V and 3.3V logic, and the MultiPlex I/Os of the A42MX24-F handle both domains natively at up to 5.0V. Its 24,000 gates implement state machines, encoders, and interface glue for motor drives, PLC I/O modules, and factory sensors. Non-volatile antifuse configuration means equipment powers up functional immediately after a brownout, without FPGA reconfiguration logic. Design security is inherent because no bitstream file exists to extract, protecting proprietary control algorithms in high-volume shipped equipment.
Recommended
ASIC Prototyping and Bridge Logic
Microchip positions the MX family as a reliable, single-chip ASIC alternative that shortens system design and development cycles. The A42MX24-F is well matched toASIC prototyping of medium-size gate-array designs and to implementing bus-bridge or co-processor glue logic before committing to a mask. The C/S-module structure maps both combinational datapath and registered pipeline logic efficiently, while D-modules provide CPLD-like wide-input AND decode for fast memory or peripheral selection. Instant-on antifuse configuration simplifies power-sequencing requirements relative to SRAM prototyping platforms.
Recommended
Transportation and Rugged Systems
Transportation and rugged electronics benefit from antifuse immunity to configuration memory upset and from the MX family's low power operation. The A42MX24-F implements I/O formatting, sensor-interface glue, and safety interlocks in vehicle-mounted controllers where instant-on operation after ignition events is mandatory. The 5.0V I/O capability interfaces directly with legacy sensor and actuator electronics common in commercial vehicles and railway equipment, while non-volatile programming removes configuration storage components that would otherwise add failure points in high-vibration environments.
Recommended
Test and Measurement Instrumentation
Bench and automated test equipment often requires deterministic, instantly available logic for timing generation, trigger control, and bus interfacing. The A42MX24-F delivers this with 24,000 gates of non-volatile antifuse fabric and PCI 2.1-compliant I/O for host integration. D-module wide decode implements fast instrument address decoding across backplane slots, and the 5.0V/3.3V MultiPlex I/O bridges mixed-voltage instrumentation buses. Because configuration is fixed at programming time, instrument behavior is fully repeatable across production units and service cycles.

Key Differentiators
- Higher density on same family architecture (vs A42MX16-F)
- Native 5.0V I/O capability (vs SRAM FPGAs (e.g., modern Lattice/Xilinx devices))
- D-module wide-decode fabric (vs A42MX09-F)
Design Notes
The 42MX architecture runs from a 5.0V core per the Microchip MX datasheet, so board supplies must deliver a regulated 5V rail with adequate transient margin for simultaneous switching of the MultiPlex I/Os. Decouple VCC with bulk capacitance plus 0.1uF ceramic caps at each supply pin pair. When interfacing 3.3V logic through MultiPlex I/Os, configure the bank accordingly and verify current limits per the DS2316 electrical tables.
Antifuse programming is permanent and irreversible. Complete full functional verification, including corner-case timing, before programming production devices, and reserve engineering spare devices for iterations. Because there is no reconfiguration, a defective design cannot be recovered by reflashing. Plan an unprogrammed-device stock buffer for repairs since a damaged FPGA must be physically replaced.
Use the D-module wide-decode resources for address and chip-select generation rather than routing wide AND functions through the general fabric, to minimize propagation delay. Keep global clock routing short and balanced across the BGA fanout. Follow the Microchip migration application note when porting 1200XL/3200DX layouts, since some legacy packages do not exist in 42MX and footprint changes may be required.
