Typical Applications

A42MX24-PQ160I is suitable for 6 applications: Legacy 5V System Migration, Industrial Control and Automation, Aerospace and Defense Logic Replacement, ASIC Prototyping and Bridging, Telecommunications Interface Boards, Test and Measurement Fixtures.

🏭

Legacy 5V System Migration

The A42MX24-PQ160I consolidates legacy PAL, GAL, and 22V10 PLD glue logic into a single 36K-gate device while interfacing directly with 5V TTL backplanes. Its 4.75V to 5.25V I/O rail and 5.0V-tolerant architecture eliminate level shifters, and antifuse permanence means the migrated design behaves identically to discrete logic on power-up with no configuration delay. Industrial temperature support (-40C to +85C) suits factory-floor retrofits.

🏭

Industrial Control and Automation

In PLC I/O modules and motor control interface boards, the A42MX24-PQ160I provides deterministic, configuration-immutable logic with 125 flexible I/O for sensor and actuator interfacing. The antifuse fabric cannot be corrupted by configuration upsets, and the dual-rail scheme bridges 3.3V control processors to 5V field-side signals. Industrial temperature rating and 160-BQFP rework-friendly pitch suit long-life industrial deployments.

✈️

Aerospace and Defense Logic Replacement

Antifuse FPGAs like the A42MX24 are historically favored in defense upgrades because programming is permanent, resistant to configuration readback, and immune to SEU-driven configuration loss. The PQ160I industrial grade supports -40C to +85C for avionic bay environments, and the 5V-tolerant I/O sustains legacy mil-spec bus interfaces. Microchip maintains the MX family as an active platform for these high-reliability replacement programs.

πŸ–₯️

ASIC Prototyping and Bridging

The MX family serves as a low-cost, high-volume ASIC alternative: the 36K-gate A42MX24 absorbs moderate-scale RTL blocks with one-time programming that locks the netlist against cloning. In ASIC bridge roles it interfaces 5V system buses with 3.3V core logic on the same die, simplifying mixed-voltage prototypes. No external PROM or boot sequence is needed, so prototypes power up with production-like behavior.

🌐

Telecommunications Interface Boards

Telecom line cards and backplane adapters built around 5V signaling use the A42MX24-PQ160I for framing, decode, and glue logic with 125 I/O and dual-rail operation. The antifuse architecture gives deterministic routing delays, useful for timing-constrained interface logic, and the 28x28 mm BQFP fits standard card formats. Its security against design theft also protects proprietary protocol implementations.

πŸ”§

Test and Measurement Fixtures

Custom test fixtures and board-level functional testers use the A42MX24-PQ160I as a fixed-pattern stimulus/response engine. One-time programming guarantees the test pattern logic cannot drift or be altered in the field, and 5V-tolerant I/O connects directly to DUT pins of legacy boards. The 125 I/O count covers wide parallel buses, and industrial temperature supports unattended production-floor equipment.

What is the price of A42MX24-PQ160I?
Pricing for A42MX24-PQ160I typically starts around 32.50 USD at single-unit quantity as of 2026-08-30, with volume discounts to roughly 22-24 USD at 1000-piece quantities from distributors. Prices fluctuate because the part is a legacy programmable logic device; confirm current stock and quotation with DigiKey, Mouser, or Octopart before ordering.
Where to buy A42MX24-PQ160I online?
The A42MX24-PQ160I is available from DigiKey (ships same day), Mouser, and via secondary distributors such as Microchip USA, Jotrin, and Veswin. It is listed on Octopart across 10 distributors for price comparison. Because this is a legacy Actel-family device, some distributors show limited stock - RFQ channels are common for volume purchases.
What is the difference between A42MX24-PQ160I and A42MX24-PQ160 (commercial grade)?
The suffix I denotes industrial temperature range (-40C to +85C), while the commercial-grade PQ160 variant is specified for 0C to +70C. Both share the same die, 36K gates, 125 I/O, dual supply rails, and identical 160-BQFP footprint, so they are pin-for-pin drop-in compatible; the industrial part can always replace the commercial part.
Is A42MX24 the same as A42MX24-PQ160I?
No - A42MX24 is the family/device name, while A42MX24-PQ160I is the full orderable MPN adding package (PQ160, 160-pin BQFP) and temperature grade (I, industrial -40C to +85C). Other orderable variants exist, such as different speed grades and the PQG208 package, which are not pin-compatible with the PQ160 footprint.
What is the best drop-in replacement for A42MX24-PQ160I?
The best drop-in replacements are other A42MX24 speed grades in the same PQ160 package, such as A42MX24-1PQ160I or A42MX24-2PQ160I (faster timing grades, same pinout). For industrial temperature, choose the I suffix variants. Antifuse FPGAs have no SRAM cross-brand pin-compatible equivalents - Xilinx and Altera parts require redesign.
Is A42MX24-PQ160I still in production?
Yes. Microchip (which acquired Actel in 2010) lists the MX family as active, marketing it as a reliable single-chip ASIC alternative and a platform for consolidating legacy 5V PLD designs. However, availability at distributors is tightening, so long-term designs should secure last-time-buy quantity planning.
Where can I download the A42MX24-PQ160I datasheet PDF?
Download the A42MX24 FPGA family datasheet from the official Microchip product page at microchip.com/en-us/product/A42MX24. The same document covers the full 42MX family including gate counts, timing models, I/O characteristics, and 160-BQFP package mechanical drawings. Distributor sites such as DigiKey and Mouser also host the PDF.
What supply voltages does the A42MX24-PQ160I require?
The A42MX24-PQ160I requires dual supply rails: 3V to 3.6V for the core and 4.75V to 5.25V for I/O, per Microchip USA product data. The dual-rail scheme lets the internal logic run on 3.3V while I/O banks interface directly with legacy 5V TTL/CMOS systems without level shifters.
Can a Xilinx FPGA replace the A42MX24-PQ160I pin-for-pin?
No. The A42MX24-PQ160I is a 0.45um antifuse OTP FPGA, and no Xilinx or Altera device offers pin-to-pin compatibility with its 160-BQFP footprint plus 5V I/O. Migration requires PCB and design changes; Microchip positions the MX family specifically as the low-risk path for retaining legacy antifuse designs.
What is the best cross-brand alternative for A42MX24-PQ160I?
There is no true cross-brand pin-compatible alternative because antifuse 5V MX FPGAs are unique to Actel/Microchip. The closest functional substitutes are Xilinx XC4000/Spartan series in PQ160 packages, but these are SRAM-based, 3.3V I/O, need a configuration PROM, and require board redesign - classify them as functional replacements only, not drop-in.
How do I program the A42MX24-PQ160I?
The A42MX24 is one-time programmable using Actel/Microchip antifuse programming hardware (Silicon Sculptor) with the Libero SoC or legacy Actel Designer software. Because programming is permanent, complete timing simulation and design verification are mandatory before programming production devices. No configuration file storage or readback is possible after programming.
Is the A42MX24-PQ160I suitable for 5V legacy system designs?
Yes - this is its core strength. The I/O rail accepts 4.75V to 5.25V operation and its 5.0V-tolerant architecture connects directly to legacy TTL/5V CMOS buses, per Microchip product documentation. This makes it ideal for integrating older PAL/GAL/PLD designs and 5V backplane interfaces into a single FPGA without level translation.
What package does the A42MX24-PQ160I use and what is its footprint?
It uses a 160-pin BQFP (Bumped Quad Flat Package, also specified as 160-PQFP, 28x28 mm body) with 0.65mm lead pitch, surface mount per the supplier device package data. Any replacement must use this exact PQ160 footprint; PQG208 variants of the same die are not footprint-compatible.
Does the A42MX24 need an external configuration PROM?
No. As an antifuse FPGA, the A42MX24-PQ160I stores its configuration internally once programmed, requiring no external serial configuration PROM, no boot time, and offering immunity to configuration upsets. This is a key advantage over SRAM FPGAs in high-reliability and harsh-environment deployments, and it simplifies BOM and board layout.

Selection Guide

Choose A42MX24-PQ160I when your design must integrate directly with legacy 5V TTL/CMOS systems, requires instant-on configuration-free startup, or must protect the programmed design from readback - hallmarks of the antifuse MX architecture. Choose A42MX24-1PQ160I or -2PQ160I if your timing closure analysis shows paths faster than the standard speed grade supports; these are same-footprint, same-temperature upgrades. Choose A42MX24-PQ160 (commercial) only for cost-sensitive designs guaranteed to stay within 0C to +70C. Choose A42MX16-PQ160I if your utilization is under ~24K gates for cost savings on the same footprint. Avoid cross-brand SRAM FPGAs such as XC4010E unless a full board redesign with 3.3V I/O and configuration PROM is acceptable - they are not drop-in replacements.

Key Differentiators

  • Native 5V I/O rail eliminates level shifters (vs XC4010E-4PQ160I)
  • Configuration-free instant-on operation (vs XC4010E-4PQ160I)
  • Industrial temperature at no package penalty (vs A42MX24-PQ160)

Design Notes

The A42MX24-PQ160I requires sequencing-aware dual rails: 3V-3.6V core and 4.75V-5.25V I/O. Decouple each supply with at least 0.1uF ceramic per VCC pin plus bulk 10uF. Antifuse devices draw near-zero configuration current and no inrush from bitstream loading, but 5V I/O switching into heavy legacy bus loads creates ground bounce - use generous ground return paths on the BQFP breakout.

Antifuse FPGAs are one-time programmable: a failed programming cycle or post-route timing miss wastes the device permanently. Complete full timing simulation in Libero SoC / Actel Designer before programming production parts, and reserve engineering-grade devices for design iterations. Also confirm speed grade ordering (standard vs -1/-2) matches your timing-critical paths.

The 160-BQFP has 0.65mm lead pitch: use a footprint per the Microchip mechanical drawing with solder-mask-defined pads for reliable reflow, and include via-stitched thermal relief under the center of the package. Keep clock traces short and, since MX routing is deterministic but not reprogrammable, budget skew statically during place-and-route.
