A42MX24-3PQG160I 概述
An FPGA (Field-Programmable Gate Array) is a class of programmable logic IC that sits above CPLDs and below ASICs in the integration hierarchy; the MX family is unique in using antifuse technology, which is one-time programmable, non-volatile, and inherently latch-up and configuration-pulse immune. This makes MX devices a reliable single-chip ASIC alternative for high-volume, cost-sensitive systems.
Key features include the 42MX fabric of C-Modules (combinational), S-Modules (sequential with D flip-flops), and D-Modules (wide-decode AND functions similar to CPLD architectures). MultiPlex I/O supports both 3.3V and 5.0V operation, programmable PCI support, and a low-power mode. The -3 speed grade indicates the fastest timing bin in the family.
The architecture is optimized for integrating legacy PLD, PAL, and GAL designs into a single low-cost device, and the 5.0 V tolerance makes it especially well suited for industrial systems, motor control, and military/defense boards that still run on 5 V rails. Typical applications include glue logic consolidation, bus interfacing, legacy ASIC replacement, and PCI bridge logic.
Design consideration: antifuse FPGAs are one-time programmable - finalize your Libero/Designer netlist before programming, and verify I/O bank voltage assignments against the 160-BQFP pinout in the 40MX/42MX datasheet (DS2316).

典型应用
A42MX24-3PQG160I 适用于 6 应用s: Legacy 5V Industrial Logic Consolidation, Defense and Avionics Upgrade Boards, PCI Bus Interface Logic, ASIC Prototype and Low-Volume Bridging, Motor Drive and Power Control Sequencing, Test and Measurement Interface Cards.
Legacy 5V Industrial Logic Consolidation
The native 5.0 V MX architecture lets designers replace boards full of 74-series PALs, GALs, and 5V glue logic with one A42MX24-3PQG160I. MultiPlex I/O accepts 5.0 V and 3.3 V signals directly, eliminating bus-holder and level-shifter components, while the antifuse fabric is immune to configuration errors at power-up - a common failure mode in SRAM FPGAs in noisy factory environments. The -40C to +85C industrial rating covers unconditioned cabinets and motor-control enclosures.
推荐
Defense and Avionics Upgrade Boards
Antifuse FPGAs are preferred in defense platforms because the programming is stored in the silicon itself: no configuration bitstream flash to corrupt, no readback of design data, and inherent resistance to SEU-induced configuration loss. The A42MX24's 36K gates consolidate legacy MIL-standard interface logic, and the 160-BQFP through-lead-style package suits rework-friendly upgrade cards. The I-suffix industrial range covers most embedded defense operating envelopes; -3 speed grade meets moderate system clock rates.
推荐
PCI Bus Interface Logic
The 42MX family explicitly supports programmable PCI implementations: the datasheet highlights MultiPlex I/O with PCI support operating at both 5.0V and 3.3V signaling levels. Designers can implement PCI target or simple master functions in the A42MX24 fabric, with the wide-input D-Modules accelerating the address decode and state-machine paths needed for 33 MHz PCI timing. The 5V/3.3V mixed I/O directly bridges legacy 5V PCI slots and 3.3V system logic without external transceivers.
推荐
ASIC Prototype and Low-Volume Bridging
Microchip positions MX as a reliable single-chip ASIC alternative for high volumes. Before committing an ASIC mask set, engineers map the RTL to an A42MX24-3PQG160I to validate functionality in silicon, and continue using it for low-volume shipments while ASIC production ramps. Because the antifuse device is non-volatile and pin-for-pin stable, prototype and production boards share the same 160-BQFP footprint, avoiding PCB respins during the transition.
推荐
Motor Drive and Power Control Sequencing
Industrial motor drives running on 5V control rails use the A42MX24 to implement PWM generation, fault-latching, and gate-driver sequencing state machines. The antifuse fabric starts operating immediately at power-up with no configuration latency, which is essential for safety-interlock and brown-out sequencing logic that must be active within microseconds. D-Modules provide the fast wide-input AND terms used in fault-vector decoding, and the industrial temperature rating matches drive ambient requirements.
推荐
Test and Measurement Interface Cards
Bench and rack instrumentation frequently retains 5V backplane signaling (VME, ISA-style, custom parallel buses). The A42MX24-3PQG160I implements bus arbitration, address decoding, and data-path formatting with 5V-tolerant I/O, connecting directly to legacy backplanes. The 125 available user I/O lines are sufficient for a full 16-bit data bus with address and control lines, and the non-volatile antifuse configuration ensures the card is functional the instant slot power is applied.

设计说明
The 42MX core runs from a single 5.0 V rail; budget supply current using the power calculator in Microchip Libero/Designer, since antifuse static current is low but dynamic current scales with clock rate and toggle activity in the 912-cell fabric. Decouple VDD with at least 0.1 uF ceramic per supply pin plus bulk 10 uF near the device. VPP (programming voltage) pins must be handled exactly as specified in DS2316 - tie per datasheet in normal operation, drive only during programming.
The 160-BQFP has a 0.65 mm pin pitch; use a solder-mask-defined land pattern per the datasheet package drawing and keep fan-out via stubs short to preserve signal integrity on the 125 user I/O. Group I/O so 5.0 V and 3.3 V bank signals do not interleave on adjacent pins, respecting MultiPlex I/O bank voltage rules. Antifuse devices cannot be re-programmed in-circuit - plan a programming socket or post-assembly programming flow.
The most common MX design error is treating the device like an SRAM FPGA: there is no configuration file, no re-work, and no partial reconfiguration. Lock your netlist and pin assignments before programming. Also confirm timing closure at the -3 speed grade using DS2316 AC tables, not simulation defaults, and remember A42MX16 and A42MX24 dies do NOT share identical pin maps despite similar package codes.
