Typical Applications
A42MX09-PLG84M is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control Systems, Defense and Avionics Hardware, Communication Backplane Glue Logic, Test and Measurement Instrumentation, ASIC Prototyping and Low-Volume Bridge.
Legacy PLD Consolidation
The A42MX09's 14K system gates allow multiple legacy PAL, GAL, and 22V10 devices to be merged into a single MX FPGA, reducing board area, BOM count, and assembly cost. Its 5.0V I/O directly connects to older TTL/CMOS buses that modern 3.3V FPGAs cannot safely interface with. Because MX uses antifuse configuration, no external boot PROM is required, preserving the single-chip simplicity of the original PLD designs. At up to 72 user I/O in an 84-PLCC footprint, the device comfortably hosts typical multi-PLD address decoding and bus-control logic.
Recommended
Industrial Control Systems
Industrial controllers often retain 5V backplanes and sensors, and the A42MX09's 5.0V architecture eliminates level-shifting circuitry, reducing parts count and improving noise margins in electrically harsh factory environments. The antifuse interconnect provides deterministic, ASIC-like timing after programming, which simplifies worst-case timing analysis for interlock and sequencing logic. The 84-PLCC J-lead package is mechanically robust and compatible with long-standing industrial SMT processes, making the MX09 a low-risk fit for control boards with multi-year production lifecycles.
Recommended
Defense and Avionics Hardware
Mature defense and avionics platforms frequently specify MX FPGAs because the silicon is fully characterized, change-controlled, and supports extended-temperature suffix options. Antifuse configuration cannot be flipped by radiation-induced configuration upsets in the same manner as SRAM FPGAs, improving configuration reliability in flight environments. The M-suffix A42MX09-PLG84M targets these extended-range applications, and the 72 I/O / 14K-gate capacity typically covers command decoding, telemetry multiplexing, and bus-interface glue logic on legacy mil-spec boards.
Recommended
Communication Backplane Glue Logic
Telecom and datacom backplanes built around 5V TTL signaling historically used MX FPGAs for slot addressing, bus arbitration, and status aggregation. The A42MX09 provides 72 I/O with predictable timing, letting designers close timing on multi-drop backplane buses without extensive constraint work. Single-chip antifuse integration removes configuration PROMs from the BOM, improving field reliability, and the PLCC-84 package supports board designs dating to the original 5V backplane era while remaining available for service and repair programs.
Recommended
Test and Measurement Instrumentation
Bench instruments and automated test fixtures benefit from the MX09's deterministic post-programming timing, since fixture logic must deliver repeatable strobe and handshake behavior across units. Its 5V I/O connects directly to legacy instrument buses and DUT interfaces that cannot tolerate 3.3V logic levels. With 14K gates, the device implements state machines, counter/timer functions, and address decode for fixture control, while the 84-PLCC through-hole-compatible J-lead footprint simplifies prototyping and repair on existing fixture boards.
Recommended
ASIC Prototyping and Low-Volume Bridge
MX FPGAs serve as a low-risk bridge between prototyping and production for ASIC-like logic: Microchip positions the MX family as a single-chip ASIC alternative for high volumes, and the same design netlist can move from FPGA verification to antifuse production without SRAM configuration concerns. The A42MX09's 14K gates suit small datapath and control blocks, and the locked-in antifuse programming gives ASIC-like security for IP protection. Designers prototype in Libero SoC, then commit the verified design to one-time-programmed production units.

Key Differentiators
- Extended-temperature M-suffix option (vs A42MX09-3PLG84)
- Single-chip antifuse configuration (vs A1240A-PL84I)
- Native 5.0V I/O architecture (vs A42MX09-3PLG84)
Design Notes
The A42MX09 operates from a 5.0V supply. Provide bulk (10uF+) and local (0.1uF) decoupling at each VCC/GND pin pair of the 84-PLCC package. Do not substitute a 3.3V rail: unlike some MX variants that support dual 3.3V/5.0V operation, this 5V-architecture device requires the correct supply per the datasheet power pin table. Verify inrush on hot-swap boards since antifuse FPGAs draw no configuration current but I/O loads may switch simultaneously.
MX antifuse devices are one-time programmable. A design change after programming requires a new physical device, so complete simulation and timing verification in Microchip Libero SoC before programming production units. Additionally, do not confuse speed-grade and temperature suffix codes: the M suffix in A42MX09-PLG84M encodes a specific speed/temperature combination that must be verified against the Microchip ordering-code table before substituting -2, -3, or I-suffix parts.
The 84-PLCC (J-lead) package uses leads along all four sides that must not be soldered rigidly to relieve thermal expansion stress; use standard PLCC land patterns per IPC guidance and avoid routing traces under the package body without solder mask. J-lead joints are inspectable with AOI, and PLCC sockets (including PLCC-to-DIP adapters) are available for prototyping - but note sockets add inductance and are unsuitable for high-speed clocking above roughly 50 MHz.
