Typical Applications
A42MX09-VQG100M is suitable for 6 applications: Defense and Avionics Systems, Legacy PLD Consolidation, Industrial Control and Automation, Secure Embedded Systems, Glue Logic and Bus Bridging, High-Volume Cost-Sensitive Products.
Defense and Avionics Systems
The A42MX09-VQG100M's military temperature grade (M suffix) and antifuse OTP fabric make it a staple of defense, avionics, and space-adjacent legacy programs. The antifuse interconnect cannot be read back, providing inherent design security, and it requires no configuration device that could fail in radiation-prone or high-vibration environments. Its 14K gates and 83 I/Os at 5V-tolerant levels interface directly with legacy military logic families, consolidating multiple PLDs into one rugged single-chip solution.
Recommended
Legacy PLD Consolidation
The MX family is explicitly positioned by Microchip as a platform for integrating legacy PLDs into a single low-cost device. Designs built from multiple 22V10-style PLDs, GALs, or first-generation FPGAs on 5V buses map naturally into the A42MX09's 684 CLBs and 3.3V/5V I/O architecture. Consolidation reduces BOM count, board area, and assembly cost while the antifuse fabric removes configuration PROMs, boot time, and configuration-related failure modes from the production system.
Recommended
Industrial Control and Automation
In industrial control, the A42MX09-VQG100M provides deterministic, boot-free logic with 83 user I/Os for interfacing sensors, drives, and backplanes. The 5V-tolerant I/O directly drives TTL-level field interfaces without translation devices, and the OTP configuration means the FPGA is functional the instant power is applied - valuable in systems that must resume control deterministically after power interruptions. Wide availability through 7 distributors supports long-term industrial spares strategies.
Recommended
Secure Embedded Systems
Antifuse OTP FPGAs are a recognized choice where bitstream confidentiality is required: unlike SRAM FPGAs, the programmed interconnect cannot be dumped or reverse-engineered from the device. The A42MX09-VQG100M suits secure communication equipment, authentication modules, and anti-tamper designs. A glue-logic security wrapper around a main processor can be implemented within the 336 cells, and the military grading supports high-assurance platforms requiring temperature-qualified components.
Recommended
Glue Logic and Bus Bridging
With 129 MHz internal and 215 MHz decode performance, the A42MX09 handles address decoding, bus arbitration, and protocol bridging between 5V legacy buses and modern controllers. The 83 I/Os accommodate full 16/32-bit address/data buses plus control signals in a single 100-pin TQFP. Because the MX fabric is OTP, decoded chip-selects are active at power-up with zero configuration latency - a practical advantage over SRAM FPGAs in systems with fast processor boot requirements.
Recommended
High-Volume Cost-Sensitive Products
Microchip positions the MX family as a high-volume, single-chip ASIC alternative. Once the design is frozen, the A42MX09-VQG100M delivers ASIC-like unit economics without NRE masks or minimum-order die commitments. The standard TQFP-100 gull-wing package flows through conventional surface-mount assembly lines, and multi-source distributor stocking (DigiKey, Mouser, OnlineComponents and others) smooths supply for long production runs in appliances, meters, and instrumentation.

Key Differentiators
- Military temperature grade with secure OTP fabric (vs A42MX09-VQG100I)
- Lower unit cost than larger same-footprint die (vs A42MX16-VQG100M)
- Boot-free antifuse operation vs SRAM FPGAs (vs A42MX16-VQG100M (and all SRAM FPGAs))
Design Notes
The MX family is antifuse one-time-programmable: a programmed device can never be erased or reprogrammed. Burn in your design with a programmer (e.g., Microchip Silicon Sculptor) only after full simulation sign-off, and build rework margin into production plans. Keep unprogrammed spare sockets or accept that a design fix requires a new physical device and, if the pinout changed, a PCB respin.
The device supports 3.3V and 5V operation; decouple each VCC pin with 0.1 uF ceramic capacitors placed within 2 mm of the pin, plus one bulk 10 uF per rail. 5V-tolerant I/O eases interfacing to TTL-era buses, but verify per-bank supply selection against your actual I/O standards - driving outputs above the selected rail can breach absolute maximum ratings.
The 100-pin TQFP (0.5 mm pitch gull-wing) requires a conformal footprint per the 42MX datasheet package drawing; use solder-mask-defined or non-solder-mask-defined pads per your assembly house capability. Dedicated clock input pins provide the lowest-skew routing - assign high-fanout clocks (targeting the 129 MHz internal limit) to these pins rather than general I/O for best timing closure.
Compliance Information
Distributor listings (PCB Electronics) indicate LEAD FREE status; RoHS compliance indicated by distributor data. Military temperature grade - not AEC-Q100 automotive qualified.
