A42MX24-2PQG160 概要
A field-programmable gate array (FPGA) is a semiconductor device containing programmable logic blocks and interconnects that can be configured after manufacturing. Within the programmable logic hierarchy, the MX family sits in the antifuse FPGA category: one-time programmable (OTP), non-volatile, and inherently design-secure. The 42MX family is built on a 0.45 um CMOS process and operates from a 3.3V/5V supply, making it a cost-effective, single-chip ASIC alternative for high-volume systems and legacy PLD consolidation.
Key features include a maximum clock frequency of 114.75 MHz, D-modules arranged around the die periphery that provide fast, wide-input decode functions similar to CPLD architectures, and a flexible 5.0V-tolerant architecture. Antifuse programming gives the device zero configuration-time at power-up, high resistance to bit-stream theft, and low static power compared to SRAM FPGAs.
The -2 speed grade balances performance and availability within the family. Logic is implemented in clocked logic blocks and combinatorial modules routed through a segmented interconnect fabric, while dedicated D-modules accelerate wide-decode functions such as address decoding and state-machine detection.
Typical applications include legacy system redesign and PLD integration, industrial control logic, glueless bus interfacing, military/industrial 5V systems, and high-volume designs where design security and instant-on operation matter more than reprogrammability.
Designers should note that MX devices are one-time programmable: prototype thoroughly in simulation and, where possible, use in-system verification before committing. Power sequencing and 5V/3.3V I/O banking must respect the datasheet electrical limits.

主な用途
A42MX24-2PQG160 の用途: 6 件s: Legacy PLD Integration and System Redesign, Industrial Control and Automation Logic, Glueless Bus and Processor Interfacing, Design-Secure High-Volume Systems, Instant-On Boot Logic and System Sequencing, 5V Military and Ruggedized Platforms.
Legacy PLD Integration and System Redesign
The A42MX24-2PQG160 is specifically positioned by Microchip as a platform for integrating legacy PLDs into a single, low-cost device. Its 36,000 gates, 912 CLBs, and 1890 logic cells absorb multiple PAL/GAL/CPLD functions from aging boards, while D-modules provide the fast wide-input AND decode functions that legacy state machines and address decoders rely on. Because the 42MX family retains a 3.3V/5V I/O architecture, it connects directly to legacy 5V buses without level shifting. The antifuse fabric programs once and powers up instantly, so a redesigned board boots identically to the original - a decisive advantage when replacing discontinued programmable logic in long-lifecycle industrial and defense equipment.
おすすめ
Industrial Control and Automation Logic
In factory automation, the A42MX24-2PQG160 implements deterministic control glue logic: encoder interfaces, interlock logic, and I/O handshake controllers. The 114.75 MHz maximum clock and -2 speed grade comfortably cover industrial timing requirements, while 125 user I/O in the 160-PQFP provides the pin count for parallel fieldbus and sensor interfaces. The 5V-tolerant architecture interfaces directly with legacy 24V-buffered and 5V TTL subsystems common on factory floors. Because the antifuse configuration is non-volatile and cannot be corrupted by brownouts or EMI-induced configuration resets, control logic keeps functioning through power disturbances - a frequent failure mode of SRAM FPGAs that must reload configuration from external flash.
おすすめ
Glueless Bus and Processor Interfacing
The wide-decode D-modules around the die periphery make the A42MX24-2PQG160 well suited to address decoding, chip-select generation, and wait-state logic for legacy microprocessor systems. D-modules deliver a fast, wide-input AND function similar to CPLD architectures, so multi-signal address-range comparisons complete in a single fast path rather than through general routing - critical for zero-wait-state bus cycles. With 125 user I/O, the device can simultaneously host a full address bus, data bus, and control strobes. Designs interfacing to processors such as the TMS320F28027 or MSP430 family can offload all memory-mapped decode and bus-buffering tasks to this FPGA, simplifying board-level timing closure.
おすすめ
Design-Secure High-Volume Systems
Antifuse FPGAs are the architecture of choice when intellectual-property protection matters. The A42MX24-2PQG160 stores no configuration bitstream in external memory - there is nothing to intercept during power-up - and programmed antifuses cannot be read back as a netlist. For high-volume consumer, industrial, or commercial products, this eliminates both the configuration flash BOM cost and the cloning risk inherent to SRAM FPGAs. Microchip explicitly markets the MX family as a reliable, single-chip ASIC alternative for high-volume platforms: 36,000 gates provide ASIC-like integration at a fraction of NRE cost and lead time, making mid-volume designs that cannot justify an ASIC economically viable with strong security.
おすすめ
Instant-On Boot Logic and System Sequencing
Because the A42MX24-2PQG160 is non-volatile, its logic is active within microseconds of power application - no configuration load time. This makes it ideal for early-boot functions: power-good monitoring logic, reset distribution, clock-enable generation, and supervisor handshaking for processors such as the AM6528 or TMS320F28335. An SRAM FPGA cannot perform these functions because it is blank during configuration. The 3.3V/5V supplies align with typical backplane rails, and the -2 speed grade handles sub-10 ns decode paths needed for prompt reset release. Pairing the MX FPGA with Microchip supervisors creates a robust deterministic power-up sequence for multi-rail systems.
おすすめ
5V Military and Ruggedized Platforms
The 42MX family's 5V architecture, antifuse reliability, and available screened variants (A42MX24-PQG160M, PQG160A) address military and ruggedized platforms that still operate on 5V logic standards. The one-time-programmable fabric has no configuration memory to upset under radiation or power transients, and the ceramic-compatible 160-PQFP 0.635 mm pitch suits long-lifecycle board designs. With 36,000 gates, designers implement bus interfaces, telemetry formatting, and command-decode logic in one device. Microchip's continuity of the MX line also supports programs with decades-long support requirements, where sourcing continuity of the exact die is as important as the electrical specification itself.

設計ノート
The A42MX24 is a one-time-programmable antifuse FPGA - there is no second chance after programming. Complete gate-level timing simulation, static timing analysis at the -2 speed grade corners, and board-level signal-integrity review before generating the fuse file. Per the 40MX/42MX family datasheet, D-modules provide the fastest wide-decode paths; make sure address-decode functions are mapped to D-modules in the Libero/MX place-and-route flow rather than general fabric to meet bus timing.
Plan for both 3.3V and 5V rails per the MX 3.3V/5V architecture. Decouple VCC and VCCA with local 0.1 uF ceramics at each supply pin pair of the 160-PQFP, plus bulk 10 uF near the device. Estimated: with 1890 logic cells at typical CMOS activity, core current is modest, but 5V I/O banks driving heavy legacy loads can dominate the power budget - compute per-bank current from your I/O loading before selecting regulators.
The 160-PQFP has 0.635 mm terminal pitch. Use surface-mount land patterns per the manufacturer package drawing, with fan-out via escape routing on 0.5 mm-pitch-compatible grids. Keep high-speed clock routing short and matched; the 114.75 MHz maximum toggle capability of the -2 grade means clock traces over 10 cm should be length-matched to associated data. Provide a solid ground plane under the die area for return-current integrity and thermal relief.
