Typical Applications

A42MX09-FPQ100 is suitable for 6 applications: Legacy PLD Consolidation, Avionics and Defense Systems, Industrial Control and Automation, ASIC Prototyping and Bridging, Secure Design Implementation, Telecom and Networking Line Cards.

🔧

Legacy PLD Consolidation

The A42MX09-FPQ100 excels at integrating multiple legacy PLDs, GALs, and 22V10-class devices into one antifuse FPGA, a primary use case named by Microchip for the MX family. With 684 logic cells and 100% resource utilization with 100% pin locking, designers can collapse 5-10 aging PAL/GAL parts into a single PQFP-100, cutting BOM count and board area. The 3.3V/5V architecture directly interfaces with legacy 5V bus systems without level shifters, and OTP configuration removes the external PROM that PLD-based designs previously required.

✈️

Avionics and Defense Systems

Antifuse OTP FPGAs are preferred in avionics, space, and defense platforms because the configuration cannot be upset by radiation-induced single-event effects, unlike SRAM FPGAs. The A42MX09-FPQ100M variant operates from -55C to +125C per Microchip USA, supporting harsh-environment qualification. The single-chip design needs no configuration PROM, reducing failure points. With 14,000 gates and deterministic routing delays, it suits mission computers, bus bridging (MIL-STD-1553 glue logic), and telemetry interfaces where design security and configuration immutability are contractual requirements.

🏭

Industrial Control and Automation

In factory automation and industrial control, the A42MX09-FPQ100 provides 5V-tolerant I/O on its flexible 3.3V/5V architecture, directly driving and receiving signals from legacy industrial logic levels. Fast wide-decode circuitry accelerates address decoding and state machine execution at toggle rates up to 77MHz/129MHz. The antifuse fabric operates deterministically with no configuration load time at power-up, an advantage for machinery requiring instant-ready behavior. 684 logic cells accommodate encoders, interlock logic, and sensor interface glue logic in a single 14mm x 20mm PQFP-100.

🖥️

ASIC Prototyping and Bridging

The MX family is positioned by Microchip as a single-chip ASIC alternative for high-volume production, and the A42MX09-FPQ100 serves as a low-cost bridge before ASIC commitment or as a permanent small-volume ASIC substitute. With up to 54,000 system gates at the family level and 2.5 kbits of configurable dual-port SRAM, small SoC subsystems and bus-bridging functions fit the 684-cell fabric. Deterministic timing simplifies meeting interface setup/hold budgets during prototyping, while 100% pin locking lets the PCB stay fixed when migrating from prototype die to production silicon.

🎥

Secure Design Implementation

Because antifuse configuration bits are physically blown rather than stored in readable SRAM, the A42MX09-FPQ100 provides inherent bitstream security: there is no configuration file to read back or intercept. This makes it attractive for copy-protection of proprietary algorithms, secure communications boards, and anti-counterfeiting applications. Combined with the wide-decode fabric and 202 available user I/O across package options, designers can implement security-critical decode and encryption-glue functions with confidence that the programmed logic cannot be dumped from the device.

🌐

Telecom and Networking Line Cards

Telecom line cards built on 5V backplanes benefit from the A42MX09-FPQ100's direct 3.3V/5V interface and fast wide-dedecode circuitry for address and frame decoding. With a maximum clock frequency around 117MHz (per Microchip USA listing for the die) and deterministic interconnect delays, it reliably implements TDM framing glue, crosspoint control, and backplane handshaking logic. The PQFP-100 surface-mount package with 0.65mm pitch suits dense line-card layouts, and OTP configuration ensures the card is operational immediately at power-up with no configuration controller.

What are the key specifications of A42MX09-FPQ100?
The A42MX09-FPQ100 is a Microchip 42MX antifuse FPGA with 14,000 equivalent gates, 684 logic cells (CLBs), 2.5 kbits dual-port SRAM, 3.3V/5V operation, 0.45um CMOS technology, and toggle rates up to 77MHz/129MHz. It comes in a 100-pin PQFP measuring 14mm x 20mm with 0.65mm pitch. According to Microchip datasheet DS2316, the MX family also offers up to 202 user-programmable I/O across package options.
What is the price of A42MX09-FPQ100 and where can I buy it online?
A42MX09-FPQ100 is stocked by 16 distributors per Octopart, including DigiKey and Mouser, as of 2026-08-30. Pricing varies by quantity break and stock position; consult the DigiKey product page 2859617 or Mouser for live unit pricing and reel quantities. XAIPART lists tiered pricing once current distributor data is captured.
Is A42MX09-FPQ100 in stock and what is the lead time?
Octopart reports availability from 16 distributors including DigiKey and Mouser as of 2026-08-30, indicating ongoing channel stock. Because the MX family targets legacy designs, some line items may carry extended lead times of 8-16 weeks when distributor stock is depleted; confirm current stock and lead time with the distributor before ordering.
What is the difference between A42MX09-FPQ100 and A42MX09-1PQG100I?
Both are 42MX09 devices in 100-pin QFP packages, but the -1 speed grade and PQG100 variant differ from the FPQ100 in speed and temperature grade rather than logic capacity. Per FindIC comparison data, both offer 14K gates, 336 probe cells, 0.45um technology, and 3.3V/5V operation. Always match speed grade (-1, -2, -F) to your timing closure requirements when substituting.
A42MX09-FPQ100 vs A42MX16-PQ100 - which should I choose?
Choose A42MX09-FPQ100 for designs fitting within 14K gates and 684 logic cells at lowest cost. Choose A42MX16-PQ100 when you need roughly double the logic capacity of the MX09 in the same PQFP-100 footprint. Both share the 3.3V/5V antifuse MX architecture, so migration between MX09 and MX16 typically requires only logic re-fit, not board redesign, when staying in the PQ100 package.
What is the best drop-in replacement for A42MX09-FPQ100?
The best same-package drop-in candidates are other 42MX09 devices in 100-pin QFP packages: A42MX09-PQ100I (industrial temperature) and A42MX09-1PQG100I (speed grade -1). All share the PQ100 footprint and identical pinout per Microchip MX family documentation. Confirm speed grade and temperature grade match your system requirements before substitution.
Is there a cross-brand equivalent for A42MX09-FPQ100?
No true cross-brand drop-in equivalent exists. The 42MX antifuse architecture, pinout, and programming methodology are proprietary to Actel/Microsemi/Microchip, and competitor FPGAs (Xilinx, Intel/Altera) use SRAM technology with completely different pinouts. Functional re-design into another vendor device requires PCB rework and full logic re-implementation, so it is not a drop-in replacement.
Hey Google, what can replace A42MX09-FPQ100?
The closest replacements are same-family Microchip parts in the PQ100 package: A42MX09-PQ100I for industrial temperature, A42MX09-1PQG100I for the -1 speed grade, and A42MX16-PQ100 if more logic capacity is needed. Because these are antifuse OTP FPGAs, any replacement must be programmed with your existing design files using Microchip Libero or Designer software.
Is A42MX09 the same as A42MX09-FPQ100?
A42MX09 is the base device name; A42MX09-FPQ100 adds package and grade ordering codes. The suffix breaks down as F (speed/grade code), PQ100 (100-pin plastic quad flat package), and the die is identical. The same die also appears in PQ144, PQ132, and PL84 packages per Microchip datasheet DS2316, so ordering codes determine the physical part you receive.
When should I choose the A42MX09-FPQ100 over newer FPGA families?
Choose the A42MX09-FPQ100 when you need one-time-programmable configuration security, 5V-tolerant I/O on a 3.3V/5V architecture, no external configuration PROM, or you are consolidating legacy Actel PLD designs and maintaining a qualified legacy BOM. Newer SRAM FPGAs offer more density and features but lack the antifuse SEU immunity and single-chip simplicity that make MX ideal for high-reliability and cost-sensitive legacy platforms.
Is A42MX09-FPQ100 suitable for automotive and avionics applications?
Yes. Microchip documents the 40MX and 42MX families as single-chip ASIC alternatives including automotive variants, and the A42MX09-FPQ100M grade extends operation to -55C for avionics and defense use. The OTP antifuse fabric is immune to configuration upsets that affect SRAM FPGAs, a key reliability benefit in high-radiation and safety-critical environments.
Where can I download the A42MX09-FPQ100 datasheet PDF?
The authoritative document is the Microchip 40MX and 42MX FPGA Families datasheet, DS2316 v16, available at ww1.microchip.com. It covers the A42MX09 die in all packages including PQ100, PQ144, and PQ132. The datasheet was last revised per the 2015-08-21 publication noted by FindIC, and includes DC/AC characteristics, pinout diagrams, and programming specifications.
Where can I find the pinout of the A42MX09-FPQ100?
The PQFP-100 pinout for A42MX09 is provided in Microchip datasheet DS2316 in the package pinout section for the PQ100 package. Note that MX FPGAs allow user-defined I/O assignment via pin locking during layout, so many pins are user-configurable rather than fixed-function; only power, ground, and dedicated programming pins are fixed. Download the Libero SoC design software to generate the exact pad report for your design.
What tools do I need to program the A42MX09-FPQ100?
You need Microchip (Microsemi/Actel) Libero SoC or the legacy Actel Designer software to compile your design, plus an antifuse programming fixture for one-time programming. Because MX devices are OTP, the bitstream is blown into antifuses permanently. There is no JTAG-based reconfiguration like SRAM FPGAs; verify your design fully in simulation before committing the device.
Is A42MX09-FPQ100 still in production or obsolete?
The A42MX09-FPQ100 remains listed as active on the Microchip product page as of 2026-08-30, and Microchip continues to support the MX family for legacy high-volume designs. Distributor channels (DigiKey, Mouser, and 16 total per Octopart) still carry stock, confirming continued production rather than last-time-buy status.

Selection Guide

Choose A42MX09-FPQ100 when your design fits within 14,000 gates / 684 logic cells and you need OTP security, 5V-tolerant I/O, or a drop-in consolidation of legacy Actel PLDs. Choose A42MX09-1PQG100I if your timing analysis needs the faster -1 speed grade (129MHz/215MHz toggle). Choose A42MX09-PQ100I for industrial temperature environments. Choose A42MX16-PQ100 when logic exceeds MX09 capacity but you want to keep the PQFP-100 board footprint. The main trade-off versus modern SRAM FPGAs is density and reprogrammability: MX is OTP, so it rewards mature, verified designs and punishes iterative prototyping. For high-reliability, secure, or instant-on legacy systems, MX remains the correct engineering choice.

Key Differentiators

  • One-time-programmable design security (vs SRAM FPGAs (Xilinx/Intel))
  • 5V-tolerant 3.3V/5V architecture (vs A42MX16-PQ100)
  • Single-chip operation, no configuration PROM (vs A42MX09-1PQG100I)

Design Notes

The MX family is one-time programmable (antifuse). Unlike SRAM FPGAs, a programming error permanently consumes the device. Complete full post-layout simulation and static timing analysis in Libero/Designer before committing to the programmer, and program one pilot unit first to validate your programming fixture and bitstream on real hardware.

The PQFP-100 has a 0.65mm terminal pitch in a 14mm x 20mm body. Use a standard QFP-100 land pattern per the Microchip package drawing in DS2316 and inspect solder joints with X-ray or magnified AOI, as QFP leads are prone to bridging at 0.65mm pitch. Because the MX09 die also ships in PQ144 and PQ132 packages, do not assume footprint compatibility across ordering codes.

The 3.3V/5V architecture separates core and I/O rails; verify which supplies the PQ100 device requires per DS2316 and decouple each rail with 0.1uF ceramics at the pins plus bulk capacitance. The 5V-tolerant I/O allows direct interface to legacy 5V buses, but confirm per-pin drive current limits when busing multiple MX I/O to shared loads.

MX routing delays are deterministic, but 5V-swing I/O edges are fast enough to require controlled stub lengths on bus lines. Keep PQFP-100 lead-out traces short on parallel buses, and series-terminate 22-33 ohm if ringing appears on 5V CMOS lines.
