A42MX24-PQ160I Übersicht
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. The MX family belongs to the one-time-programmable (OTP) antifuse FPGA category, positioned within the broader programmable logic hierarchy: FPGA -> programmable logic device -> digital IC -> semiconductor. Unlike SRAM FPGAs, antifuse programming is permanent, radiation-tolerant by nature, and requires no configuration PROM, making MX devices a reliable single-chip ASIC alternative for high-volume systems.
Key features include a flexible 5.0V-tolerant architecture with dual supply rails (3V to 3.6V core and 4.75V to 5.25V I/O per Microchip USA data), 0.45um antifuse process technology, and 125 programmable I/O supporting legacy 5V logic integration. The MX family enables consolidation of legacy PLDs, PALs, and glue logic into a single low-cost device, reducing board space and component count.
The Actel antifuse architecture (R-Cell and C-Cell modular blocks) delivers deterministic routing and inherent security against design theft, since the programmed netlist cannot be read back. This makes the A42MX24 well suited to applications where IP protection and configuration immutability matter.
Typical applications include industrial control systems, legacy 5V system migrations, aerospace and defense logic replacement, telecommunications interface boards, and high-volume consumer/industrial ASIC prototyping. The 160-BQFP package (28x28 mm) offers 0.65mm pin pitch for rework-friendly assembly.
Design consideration: antifuse FPGAs are one-time programmable - fully verify your design in simulation (Libero SoC or Actel Designer toolchain) before programming, as no design iteration is possible on the same device.

Typische Anwendungen
A42MX24-PQ160I ist geeignet für 6 Anwendungs: 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.
Empfohlen
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.
Empfohlen
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.
Empfohlen
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.
Empfohlen
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.
Empfohlen
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.

Wichtigste Unterscheidungsmerkmale
- Native 5V I/O rail eliminates level shifters (vs. XC4010E-4PQ160I)

- Industrial temperature at no package penalty (vs. A42MX24-PQ160)
Designhinweise
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.
