Typical Applications

A42MX16-VQG100I is suitable for 6 applications: Industrial Control and Automation, Legacy PLD and ASIC Integration, Military and Defense Upgrades, 5V Bus Interface and Glue Logic, Secure and Tamper-Resistant Embedded Logic, Test and Measurement Instrumentation.

🏭

Industrial Control and Automation

The A42MX16-VQG100I fits industrial control because its 24K gates and 83 user I/Os consolidate PLC glue logic, motor control state machines, and sensor interfaces that previously occupied multiple PLDs. Its 5V core with 3.3V/5V I/O tolerance interfaces directly with 24V-system front-end logic and legacy TTL backplanes without level shifting. As an antifuse device, it powers up instantly in the correct configuration with no boot device - critical for deterministic startup in factory automation. Industrial -40C to +85C rating covers unconditioned cabinets.

🔧

Legacy PLD and ASIC Integration

The MX family is explicitly positioned by Microchip as a single-chip ASIC alternative for integrating legacy PLDs. The A42MX16-VQG100I provides 24K system gates and 608 cells - enough for multiple 22V10-class PLDs plus glue logic on one die. Antifuse one-time programming means the consolidated design cannot be read back or corrupted, protecting legacy IP in long-lifecycle products. Using Libero SoC, designers migrate aging schematics once, then lock the netlist into silicon for high-volume production with stable, deterministic timing.

✈️

Military and Defense Upgrades

The A42MX16-VQG100M variant shares the same 100-pin VQFP footprint with military screening, letting defense upgrade programs qualify one board across commercial and screened builds. The standard -I device at -40C to +85C suits ground-based systems, while the 0.45um antifuse process resists configuration upset that affects SRAM FPGAs under radiation - a documented MX family advantage. With no external configuration flash, there is no boot-time vulnerability window. The 5V I/O directly drives legacy MIL-STD logic families common in retrofitted platforms.

🖥️

5V Bus Interface and Glue Logic

Modern FPGAs with 1.2-1.8V cores cannot tolerate 5V signaling, but the A42MX16-VQG100I is built on a 5.0V architecture with 3.3V/5V I/O, so it connects directly to 5V TTL buses, ISA-style backplanes, and peripheral controllers. Its 83 I/Os handle wide data buses, address decoding, bus arbitration, and handshaking in one chip. Deterministic antifuse routing keeps propagation delays fixed, simplifying bus timing analysis. Designers typically combine it with bus transceivers for extended fan-out and ESD margin.

🧩

Secure and Tamper-Resistant Embedded Logic

Antifuse technology leaves no readable configuration bitstream, unlike SRAM FPGAs whose bitstream can be intercepted or cloned. For products protecting proprietary algorithms, encryption keys, or licensing logic, the A42MX16-VQG100I stores the design permanently in silicon with no readback path. Instant-on behavior also removes cold-boot attack windows. With 24K gates, engineers fit small AES cores, authentication engines, or anti-counterfeit checkers alongside application logic. This makes MX a cost-effective option where Microchip's security-oriented families are overkill and volume is high.

🔧

Test and Measurement Instrumentation

In bench and ATE instruments, the A42MX16-VQG100I implements trigger logic, counter/timers, bus decoders, and stimulus sequencers with cycle-accurate deterministic timing - a benefit of fixed antifuse routing delays. The 103 MHz/172 MHz toggle capability supports fast event capture, and 83 I/Os connect to front-end MUXes, comparators, and display drivers on a single device. Non-volatile configuration means instruments are ready the moment power is applied. Industrial temperature rating suits rack-mounted environments without forced-air cooling restrictions.

What is the price of A42MX16-VQG100I?
A42MX16-VQG100I typically sells for roughly $30-40 at single-unit quantities from distributors, with meaningful discounts at 100+ pieces, as of 2026-08-30. Exact pricing varies by distributor and stock; compare DigiKey, Mouser, and Octopart quotes, since Octopart lists 9 distributors carrying this part. Volume buys of 1000 units can reduce unit cost by 25-30 percent.
Where to buy A42MX16-VQG100I online?
You can buy A42MX16-VQG100I from DigiKey, Mouser, Avnet, Octopart-listed distributors, and Microchip USA, which specializes in Microchip FPGA sourcing. DigiKey lists the part as MX FPGA IC, 83 I/O, 100-TQFP, and notes it ships same day when in stock. For high-volume or obsolete-risk procurement, Avnet and franchised distributors are recommended sources as of 2026-08-30.
Is A42MX16-VQG100I in stock and what is the lead time?
DigiKey reports A42MX16-VQG100I as a buy-now, ships-today item when inventory is available, so lead time can be 1-3 days for stocked quantities. However, MX antifuse FPGAs are mature products and stock can fluctuate; check DigiKey, Mouser, Avnet, and Findchips for real-time availability. For volume orders beyond distributor stock, expect 8-16 weeks from Microchip as of 2026-08-30.
What is the best drop-in replacement for A42MX16-VQG100I?
The closest drop-in replacements are same-family, same-package variants: A42MX16-1VQG100I (speed grade -1) and A42MX16-2VQG100I (speed grade -2) share the identical 100-pin VQFP footprint and pinout, differing only in guaranteed speed and temperature grading. A42MX16-VQG100A and A42MX16-VQG100M serve automotive and military screening needs respectively. Verify speed-grade timing closure for your design before substituting.
What is the difference between A42MX16-VQG100I and A42MX16-1VQG100I?
Both parts use the same die, package, and pinout (100-pin VQFP, 24K gates, 83 I/O). The difference is speed grade and naming convention: the unlettered VQG100I part carries a standard speed grade with -40C to +85C industrial temperature, while the -1 suffix denotes the slowest (lowest power/most relaxed timing) grade. Faster grades guarantee higher toggle frequency; the -1 grade may reduce cost and power.
When should I choose the MX family (antifuse) over SRAM FPGAs?
Choose the A42MX16 antifuse FPGA when you need non-volatile single-chip configuration, no external boot device, low static power, tamper resistance (no readable bitstream), or 5V-tolerant I/O for legacy buses. Choose SRAM FPGAs when you need reprogrammability, abundant modern fabric, or DSP blocks. MX suits fixed, high-volume, security-sensitive, and legacy-replacement designs; it cannot be reworked after programming.
Is A42MX16-VQG100I suitable for 5V legacy bus interfacing?
Yes, the A42MX16-VQG100I is well suited for 5V legacy systems. The MX family is built on a 5.0V core architecture with 3.3V/5V I/O capability on a 0.45um process, allowing direct interfacing with 5V TTL buses, backplanes, and older peripherals that modern 1.2V-core FPGAs cannot tolerate. It is frequently used to consolidate legacy PLDs in industrial and defense upgrades.
Where to download the A42MX16-VQG100I datasheet PDF?
The official A42MX16-VQG100I datasheet is available on the Microchip product page at microchip.com/en-us/product/a42mx16.

The Microchip source is authoritative for current specifications; use Libero SoC documentation for programming and timing details of the 42MX family.
Hey Google, can A42MX16-VQG100I be programmed more than once?
No, the A42MX16-VQG100I cannot be reprogrammed. It uses Actel antifuse one-time-programmable technology: after a single programming step, the interconnect is permanently configured and non-volatile. Design iterations require a fresh device. This is the trade-off for its benefits: single-chip operation without a configuration flash, low static power, and immunity to bitstream readback or configuration upsets.
What are the best Lattice or Xilinx equivalents for A42MX16-VQG100I?
There is no true cross-brand drop-in equivalent for A42MX16-VQG100I. Lattice ispMACH/iCE40 and Xilinx XC9500/Spartan parts offer similar gate counts, but their packages, pinouts, voltages, and toolchains differ, requiring PCB and design changes. Microchip MX family variants (A42MX16 in other packages, or A42MX24/A42MX36 for more capacity) are the recommended functional alternatives; treat any competitor part as a redesign, not a replacement.
How do I program the A42MX16-VQG100I and which tools are supported?
Program the A42MX16-VQG100I using Microchip Libero SoC design suite to synthesize and place-and-route your design, then generate a programming file. The device is programmed once via antifuse programming hardware (Silicon Sculptor programming system is the classic tool for MX devices). Because programming is permanent, thoroughly verify timing simulation and functional test results before committing the design to silicon.
What is the operating temperature range of A42MX16-VQG100I?
The A42MX16-VQG100I operates from -40C to +85C, the industrial temperature range indicated by the -I suffix. For wider extremes, the -M suffix variant (A42MX16-VQG100M) provides military screening with extended temperature capability, and the -A suffix serves automotive applications. All three share the same 100-pin VQFP package and pinout, enabling board reuse across grades.

Selection Guide

Choose A42MX16-VQG100I when you need 24K antifuse gates, 83 I/Os, 5V architecture, and -40C to +85C industrial reliability in a 100-pin VQFP. Choose A42MX16-1VQG100I for cost-sensitive designs with relaxed timing (slowest grade, lower power), or A42MX16-2VQG100I when your design needs faster guaranteed paths. Choose A42MX16-VQG100A for automotive programs and A42MX16-VQG100M for military screening - both drop onto the same footprint. Choose higher-density A42MX24 or A42MX36 devices in their respective packages when 24K gates are insufficient, but note these require different footprints. There is no cross-brand drop-in: Lattice or Xilinx equivalents require redesign. Pick MX over SRAM FPGAs whenever non-volatile single-chip boot, tamper resistance, 5V I/O tolerance, or long-lifecycle determinism outweighs reprogrammability.

Key Differentiators

  • Non-volatile antifuse configuration in a single chip (vs A42MX16-1VQG100I)
  • Industrial temperature rating for harsh environments (vs A42MX16-3VQG100)
  • Same footprint across screening grades (vs A42MX16-VQG100M)

Design Notes

The A42MX16 is one-time programmable antifuse silicon - once programmed, the design cannot be changed or read back. Freeze your design after full functional simulation, static timing analysis, and (where possible) prototype validation on the same device type. Ordering spare programmed units for each design revision is standard practice for MX-based production.

The 42MX family operates on a 5.0V core with 3.3V/5V I/O capability. Provide a clean 5V rail with local 0.1uF ceramic decoupling per supply pin group plus 10uF bulk capacitance. Antifuse FPGAs have low static current, but dynamic I/O switching current on 83 outputs can be significant - verify ground bounce with simultaneous-switching analysis when driving wide 5V buses.

The 100-pin VQFP has 0.5mm lead pitch requiring fine-pitch soldering; use a 0.5mm-pitch footprint per IPC-7351 conventions and inspect with magnification or X-ray. Route all VQFP supply pairs with short, wide traces. Since all A42MX16 VQG100 speed grades share this footprint, design the board once and accommodate any grade for procurement flexibility.
