A42MX24-1TQG176I Übersicht
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, making it a single-chip ASIC alternative. The MX family sits within the broader taxonomy: FPGA -> programmable logic device -> digital IC, and is specifically optimized as a cost-effective, high-volume platform for consolidating legacy PLD designs.
Key features include the flexible 5.0V-tolerant architecture, multiPlex I/Os supporting mixed-voltage 3.3V/5.0V systems, programmable PCI support, and a low-power mode. The A42MX24 and A42MX36 devices additionally contain D-modules arranged around the device periphery, providing wide-decode circuitry that delivers fast, wide-input AND functions similar to CPLD architectures.
Architecturally, the MX fabric combines C-modules (combinational), S-modules (sequential with flip-flops), and D-modules (wide decode), enabling efficient glue logic, state machines, and bus-interface functions. The act-1 style logic granularity suits legacy schematics and older HDL designs common in industrial platforms.
Typical applications include industrial control and automation, legacy PLD consolidation, 5V mixed-voltage bus bridging (including PCI), and high-volume embedded systems where a single-chip ASIC alternative reduces BOM cost.
Design consideration: this is an antifuse/flash-style mature family programmed via Microchip Libero/Microsemi Designer tools; verify programmer availability and lock design files early, and confirm I/O voltage domain assignments when mixing 3.3V and 5.0V banks.

Typische Anwendungen
A42MX24-1TQG176I ist geeignet für 6 Anwendungs: Legacy PLD Consolidation, 5V Mixed-Voltage Bus Bridging, Industrial Control and Automation, Programmable PCI Interfaces, Test and Measurement Instrumentation, High-Volume Embedded Systems.
Legacy PLD Consolidation
The MX family is explicitly positioned by Microchip as a reliable, single-chip ASIC alternative for integrating legacy PLDs, PALs, and glue logic into one low-cost device. The A42MX24's 36,000 gates and 912 cells absorb multiple 22V10-class devices, while the flexible 5.0V architecture matches legacy board voltage rails without level shifters. Non-volatile one-time programming means the consolidated design powers up instantly with no configuration device, cutting BOM count and board area in high-volume industrial platforms.
Empfohlen
5V Mixed-Voltage Bus Bridging
The A42MX24-1TQG176I's multiPlex I/Os support mixed-voltage systems at both 5.0V and 3.3V simultaneously, per the DS2136 datasheet, making it ideal where modern 3.3V logic must talk to legacy 5V buses. With 150 user I/Os and programmable I/O banks, engineers can bridge VME-style backplanes, 5V parallel buses, or sensor networks into newer controller logic on one chip, eliminating discrete level translators and preserving signal integrity across the 0.45 um tolerant I/O structure.
Empfohlen
Industrial Control and Automation
Industrial-grade temperature rating of -40C to +85C plus 5V noise immunity make the A42MX24-1TQG176I suited for factory automation controllers, motor-drive interface logic, and machine I/O boards. D-modules around the device periphery provide fast, wide-input AND decode functions similar to CPLD architectures, enabling rapid address decoding and safety interlock logic. Non-volatile configuration ensures deterministic startup in environments where boot-time configuration loading is undesirable or where power glitches must not corrupt logic state.
Empfohlen
Programmable PCI Interfaces
The 42MX family delivers programmable PCI support through its I/O structure, operating at both 5.0V and 3.3V signaling environments per Microsemi documentation. The A42MX24's 150 I/Os and wide-decode D-modules implement PCI target or simple master interfaces, address decoding, and DMA handshake glue. For legacy industrial PCs and instrumentation cards retaining 5V PCI slots, this device provides a single-chip, RoHS-compliant interface fabric that modern low-voltage FPGAs cannot directly connect to without translators.
Empfohlen
Test and Measurement Instrumentation
Bench and rack instrumentation frequently mixes legacy 5V trigger buses, front-panel logic, and newer 3.3V digitizer sections; the A42MX24-1TQG176I bridges these domains on one chip with its mixed-voltage multiPlex I/O. Low-power mode helps conserve budget in multi-card mainframes, while industrial temperature rating handles long-duty-cycle thermal environments. Its 36K gates accommodate trigger state machines, clock dividers, and handshaking logic that would otherwise require several fixed-function devices, shortening design cycles for instrument variants.
Empfohlen
High-Volume Embedded Systems
Microchip positions MX as a high-volume platform, and the A42MX24-1TQG176I fits cost-sensitive embedded products needing configurable logic without FPGA-class pricing or configuration memory. One-time programmability prevents design theft and bitstream-corruption field failures, and Tray packaging supports automated assembly. Long-term availability commitments (distributors cite EOL references as distant as 2048) give OEMs supply-chain confidence for products with 10-20 year service lives such as utility meters, elevator controllers, and building automation nodes.

Wichtigste Unterscheidungsmerkmale
- Native 5.0V tolerant architecture (vs. A42MX16-3TQG176)
- Industrial temperature grade (vs. A42MX24-1TQG176)
- RoHS-compliant green package (vs. A42MX24-1TQ176I)
Designhinweise
The A42MX24 supports both 3.3V and 5.0V operation. In mixed-voltage designs, assign each I/O bank's voltage per the multiPlex I/O rules in datasheet DS2136 - a bank tied to 3.3V is 5V tolerant on inputs but verify output swing requirements for 5V receivers. Decouple VCC and VCCA pins with at least 0.1 uF ceramic caps per power pin plus bulk capacitance near the device. Confirm per-bank current limits against DS2136 I/O tables before driving heavy loads.
This is a one-time-programmable mature family: there is no re-programming after a design bug is fused in. Lock source projects, constraint files, and programmer access (Libero SoC / Microsemi Designer plus supported programming hardware) before production. Also note the -I suffix denotes industrial temperature (-40C to +85C); substituting the commercial A42MX24-1TQG176 in fielded equipment risks failures below 0C.
The 176-TQFP (24x24 mm body, 0.5 mm pitch) requires a nominal 0.5 mm-pitch land pattern per Microchip package drawing; use solder-mask-defined pads and inspect with AOI or X-ray for center-leader opens common on fine-pitch QFPs. Keep unused I/Os programmed as outputs driving low or inputs with defined pull to prevent floating-node noise in 5V systems.
