A42MX16-2TQG176I Descripción general
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable routing, allowing designers to implement custom digital logic without fabricating an ASIC. Within the programmable logic hierarchy, the MX family sits as a low-cost, high-volume platform positioned as a reliable single-chip ASIC alternative and a consolidation vehicle for legacy PLD designs.
Key features include an efficient, flexible 5.0V-tolerant architecture, 0.45um process technology, and maximum toggle/clock frequencies of 129 MHz and 215 MHz as cited by distributor data. The -2 speed grade with industrial (I) temperature rating makes this part suitable for environments without commercial-grade temperature guarantees. The device is lead-free per distributor listings.
Technically, the A42MX16 provides 608 CLBs implemented in a CMOS antifuse-style architecture originally developed by Actel and continued by Microsemi and now Microchip. The MX family is designed for designers integrating multiple legacy PLDs, PALs, and GALs into one low-cost device, reducing board count, inventory SKUs, and assembly cost in high-volume production.
Typical applications include legacy PLD consolidation, glue-logic integration, industrial control boards, and 5V-legacy system upgrades where newer low-voltage FPGAs cannot directly interface with 5V TTL buses.
Design consideration: because this is a 5V/3.3V dual-rail architecture, verify power sequencing and I/O bank voltage compliance early in the design, and confirm one-time-programmability implications for field-update requirements before committing to the platform.

Aplicaciones típicas
A42MX16-2TQG176I es adecuado para 6 aplicacións: Legacy PLD Consolidation, Industrial Control Systems, 5V Legacy System Interface, ASIC Prototyping and Bridge Logic, Communications and Networking Interface Cards, Test and Measurement Equipment.
Legacy PLD Consolidation
The A42MX16-2TQG176I excels at consolidating multiple legacy PALs, GALs, and 22V10-class PLDs into a single 24K-gate device, as Microchip explicitly positions the MX family for integrating legacy PLDs into one low-cost device. Its 5.0V-tolerant architecture matches the 5V TTL I/O levels of the legacy components being replaced, eliminating level-shifting circuitry. Designers typically migrate the original ABEL or CUPL equations into Libero SoC and fit them into the 608 CLBs, cutting board area, part count, and procurement SKUs while retaining the original through-hole era timing margins at 129/215 MHz maximum frequencies.
Recomendado
Industrial Control Systems
With an industrial temperature rating of -40C to +85C (TA) and dual 3.3V/5V supply capability, the A42MX16-2TQG176I suits factory automation controllers, motor-drive interface boards, and PLC I/O modules. The 140 user I/O provide ample pins for parallel sensor and actuator interfaces, while the one-time-programmable antifuse fabric gives deterministic timing and immunity to configuration bitstream corruption from industrial noise. Because the device powers from a 4.5V~5.5V rail, it connects directly to 5V industrial logic without translators, and the TQFP-176 package withstands typical industrial reflow and vibration profiles.
Recomendado
5V Legacy System Interface
Older backplane and equipment designs built around 5V TTL cannot directly interface with modern 1.8V/2.5V FPGAs. The A42MX16-2TQG176I accepts a 4.5V~5.5V core/IO supply, letting it sit directly on a 5V VME, ISA-era, or custom parallel bus. Its 24K gates absorb address decoding, bus arbitration, wait-state generation, and glue logic that previously occupied dozens of 74-series devices. The 0.45um process and MX architecture tolerate the 5V signal environment natively, making this part a common choice for medical equipment service boards, test fixtures, and avionics ground equipment still locked to 5V ecosystems.
Recomendado
ASIC Prototyping and Bridge Logic
Microchip markets MX as a reliable single-chip ASIC alternative, making the A42MX16-2TQG176I useful for low-volume ASIC bridge logic, mask-rom emulation, and prototyping of small gate-array designs. The one-time-programmable antifuse fabric provides ASIC-like determinism - no configuration time at power-up and consistent interconnect delay - which matters when emulating an ASIC's power-up behavior. Designers use the 608 CLBs to map netlists generated from ASIC synthesis flows, and the 215 MHz class routing supports moderate clock domains during functional verification before mask commit.
Recomendado
Communications and Networking Interface Cards
Interface cards for legacy telecom and networking equipment frequently need 5V-tolerant glue logic, address decoders, and simple protocol state machines. The A42MX16-2TQG176I implements these functions with 140 I/O and clock rates up to 129 MHz for the -2 grade, sufficient for E1/T1 framing support logic, HDLC framing assists, and backplane handshaking. The dual-rail operation (3V~3.6V and 4.5V~5.5V) lets one device bridge a modern 3.3V microcontroller section to a 5V line-card section, and the industrial temperature rating supports outdoor and unconditioned telecom cabinets.
Recomendado
Test and Measurement Equipment
Bench instruments, automated test equipment (ATE), and rack systems from the 5V era rely on programmable logic for trigger logic, timing generators, and scan controllers. The A42MX16-2TQG176I's deterministic antifuse timing suits precision trigger paths, and its 24K gates absorb counter/timer and comparator-interface logic. Because one-time programming removes configuration boot time, instruments power up in their functional state immediately - an advantage over SRAM FPGAs in production test environments where every second of boot delay counts. The TQFP-176 footprint eases replacement in existing socket-compatible designs.

Notas de diseño
The A42MX16-2TQG176I uses dual supply ranges of 3V~3.6V and 4.5V~5.5V per the MX architecture. Decouple each VDD pin pair on the TQFP-176 with 0.1uF ceramic capacitors placed within 3 mm of the pin, plus bulk 10uF at the board level. Since MX devices are one-time programmable with no configuration current surge, inrush is dominated by decoupling charge, but 5V-rail ripple still affects I/O timing margins - regulate with an LDO or buck rated for the 5V rail load of 140 switching I/O.
MX antifuse FPGAs are one-time programmable: unlike SRAM FPGAs there is no reconfiguration, so functional bugs require a new device. Fully verify the design in simulation and, if possible, prototype on a faster/lower-cost die-mate before committing industrial-grade -2 parts to production. Also confirm the temperature grade in the ordering code: A42MX16-2TQG176 (commercial, 0C~+70C) and A42MX16-2TQG176I (industrial, -40C~+85C) are physically identical but not interchangeable in specification.
The 176-TQFP (24x24 mm) has a 0.5 mm pin pitch - specify a nominal 0.5 mm pitch land pattern per the Microsemi/Microchip 40MX/42MX datasheet DS2136 package section and use solder-mask-defined pads to reduce bridging risk in reflow. Fan out with 0.2 mm via-in-escape traces; all 176 pins are perimeter-mounted, so route the two dedicated clock inputs with short, direct traces and a local ground return to preserve the 129 MHz class timing.
