Typical Applications
A42MX09-2VQG100 is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control Systems, Military and Aerospace Retrofits, Bridge and Glue Logic in 5V Systems, Test and Measurement Equipment, ASIC Prototyping and Low-Volume Production.
Legacy PLD Consolidation
MX FPGAs were explicitly designed to integrate multiple legacy PAL/GAL/22V10 PLDs into one chip. The A42MX09-2VQG100's 14K gates and 336 cells absorb dozens of small PLDs, while its 5.0V architecture directly interfaces with legacy TTL and 5V bus logic without level shifters. The -2 speed grade's 161 MHz internal performance comfortably covers state machines and decoders that ran in older PLDs. Consolidation reduces board area, power, and assembly cost, and Microchip's MX family documentation provides migration guidance for PLD designs.
Recommended
Industrial Control Systems
In factory automation and motor control backplanes still running 5V logic, the A42MX09-2VQG100 interfaces PLC I/O, encoders, and sensors directly. Its 83 user I/O in the compact 100-pin TQFP provides ample pins for parallel buses and discrete signals, and dual 3.3V/5V operation bridges old and new board sections. The non-volatile MX configuration eliminates external configuration devices, improving reliability in electrically noisy industrial environments. Industrial-temp variants such as A42MX09-VQG100I extend operation to -40C to +85C.
Recommended
Military and Aerospace Retrofits
The MX family has a long heritage in defense and aerospace programs, and the A42MX09-1VQG100M military variant in the identical VQG100 footprint lets long-life programs refresh obsolescent boards with the same 14K-gate die. The 5.0V architecture matches many legacy mil-spec interfaces, and the single-chip configuration approach avoids soldered-in configuration flash that complicates hi-rel qualification. Design teams migrating from military MX parts can share constraints and test vectors with the -2 commercial grade during prototyping.
Recommended
Bridge and Glue Logic in 5V Systems
Modern low-voltage FPGAs cannot directly drive 5V CMOS inputs, but the A42MX09-2VQG100's 5.0V-tolerant architecture acts as a native bridge between a 3.3V microprocessor section and 5V peripherals such as memory, ADCs, and communication ports. With 83 I/O and 161 MHz internal speed, it implements bus arbitration, wait-state generation, byte-swap logic, and interrupt controllers. The 0.5 mm pitch TQFP-100 is hand-reviewable and reworkable, which suits mixed-voltage retrofit engineering work.
Recommended
Test and Measurement Equipment
Bench instruments and rack systems frequently combine legacy 5V backplanes with modern interfaces; the A42MX09-2VQG100 implements scan chains, trigger logic, and programmable timing generators at 161 MHz internal performance. The deterministic MX routing architecture yields repeatable timing between units, important for calibration across a product line. Tray packaging supports efficient handling in production, and the same footprint accommodates the faster -3 grade (A42MX09-3VQG100) if timing margins tighten in later revisions.
Recommended
ASIC Prototyping and Low-Volume Production
The MX family is positioned by Microchip as a reliable single-chip ASIC alternative. Designers can prototype gate-level netlists in the A42MX09-2VQG100's 14K gates before committing to mask-based ASICs, or simply produce the FPGA in low-to-mid volumes. The 0.45 um process and mature timing models mean no retargeting surprises, and the same-package MX16 die provides a capacity upgrade path without PCB changes. Non-volatile configuration means instant-on behavior identical to an ASIC in the system.

Key Differentiators
- Optimized price/performance mid-speed grade (vs A42MX09-3VQG100)
- Commercial cost level for long-life designs (vs A42MX09-1VQG100M)
- 14K gate capacity with same-package upgrade path (vs A42MX16-2VQG100I)
Design Notes
The MX family operates from a dual 3.3V/5V supply scheme. Verify per-bank current consumption in the Microsemi/Microchip A42MX09 datasheet using the Designer tool power estimator before finalizing your rail sizing; 83 outputs switching simultaneously can create ground bounce, so place decoupling capacitors (100 nF per supply pin plus bulk 10 uF) directly at the package corners. The 0.45 um process draws essentially no static leakage, but dynamic power scales with toggle rate and load capacitance.
The 100-pin TQFP with 0.5 mm lead pitch requires solder-mask-defined pads sized per IPC-recommended TQFP footprints. Keep trace stubs short on global clock inputs, since MX dedicated clock resources assume low-skew board routing. Exposed lead fingers allow straightforward visual inspection; add fiducials on two opposite corners of the 14x14 mm body for pick-and-place alignment.
Do not substitute the -2 speed grade into timing-critical paths designed for the -3 grade: the MX09 -2 grade delivers 161 MHz internal performance versus the faster -3. Also, the commercial-temperature A42MX09-2VQG100 must not be used in industrial enclosures; select A-suffix industrial or M-suffix military variants instead. Finally, MX antifuse-style devices are one-time-programmable in system use - reserve the equivalent design netlist in version control.
