A42MX16-PQG160I Übersicht
A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that engineers configure in the field, sitting within the broader hierarchy of programmable logic devices (PLDs) - above CPLDs in density and below ASICs in volume cost. The MX family uses antifuse programmability, meaning connections are permanently set at programming time, which yields very low static power, high resistance to configuration corruption, and inherent design security compared to SRAM-based FPGAs that load their bitstream from external memory at every power-up.
Key features of the A42MX16 include its efficient 5.0V-tolerant architecture, single-chip ASIC-alternative role for legacy PLD integration, 0.45um process technology, and system speeds reported at 103 MHz (toggle) and 172 MHz (internal performance figures per family documentation). The antifuse fabric eliminates configuration PROMs, reducing bill-of-materials count and improving reliability in high-vibration and radiation-sensitive environments.
Technically, the device provides 608 logic elements (cells) organized into the MX compile-and-route fabric supported by Microchip Libero SoC design software. Because configuration is one-time programmable, designs benefit from latch-up immunity to bitstream upset, and no external flash is required - a decisive advantage in defense, avionics, and industrial systems where configuration integrity is mandatory.
Typical applications include glue logic consolidation of legacy PLD/ASIC designs, industrial control interfaces, military and aerospace subsystems requiring secure non-reprogrammable logic, and communication backplane bridging where 5V-tolerant I/O remains essential.
Designers should note that antifuse devices cannot be reprogrammed in-system; a programming pinout and programming equipment are required during production, so board bring-up should be planned with programming access in mind.

Typische Anwendungen
A42MX16-PQG160I ist geeignet für 6 Anwendungs: Legacy PLD and ASIC Consolidation, Military and Aerospace Subsystems, Industrial Control Interfaces, Communication Backplane Bridging, Test and Measurement Equipment, Medical Device Control Logic.
Legacy PLD and ASIC Consolidation
The Microchip MX family is explicitly positioned as a single-chip ASIC alternative for integrating multiple legacy PLDs, PALs, and GALs into one low-cost device. The A42MX16-PQG160I provides 24,000 system gates and 125 user I/O, enough to absorb several 22V10-class or small CPLD devices at once, cutting board area, BOM line items, and assembly cost. Its 5.0V-tolerant architecture directly interfaces with legacy 5V logic levels that modern FPGAs cannot accept, removing level-shifter stages. Because the antifuse fabric is one-time programmable, consolidated designs retain the permanent, tamper-resistant configuration behavior familiar from mask-programmed parts.
Empfohlen
Military and Aerospace Subsystems
Antifuse FPGAs are a mainstay in defense and aerospace electronics because the configuration is physically programmed once and cannot be corrupted by radiation-induced bitstream upset, unlike SRAM FPGAs that reload configuration from external memory at each power cycle. The A42MX16-PQG160I's industrial -40C to +85C rating, 125 user I/O, and absence of external configuration devices simplify qualification of secure subsystems such as telemetry encoders, bus interfaces, and sensor front-end pre-processing. Design security is inherent: no bitstream file can be read back from a programmed device, protecting proprietary logic in programs with long service lives.
Empfohlen
Industrial Control Interfaces
In factory automation, motor control panels, and process instrumentation, the A42MX16-PQG160I consolidates address decoding, state machines, and bus-bridging logic that would otherwise occupy several TTL/CPLD devices. The 4.5V to 5.5V supply range tolerates noisy industrial 5V rails, and the industrial -40C to +85C temperature grade covers unconditioned cabinets. With 125 user I/O in a 0.65 mm-pitch PQFP-160, the device terminates parallel buses and field-signal banks on a single footprint. JTAG boundary scan (TDI-to-TDO chain per the family datasheet) enables production interconnect testing of dense industrial boards without a bed-of-nails fixture.
Empfohlen
Communication Backplane Bridging
Telecom and datacom backplanes still deployed with 5V signaling benefit from the A42MX16-PQG160I's direct 5V-tolerant I/O and 24K-gate fabric for protocol glue, multiplexing, and hot-swap supervisory interfacing. The device bridges legacy backplane buses to newer control processors without external translation ICs, and its fixed antifuse routing guarantees deterministic, unchanging timing across the entire production life - a requirement in systems certified once and deployed for decades. The 103 MHz / 172 MHz performance figures of the MX fabric cover typical backplane state-machine and framing-clock frequencies with margin.
Empfohlen
Test and Measurement Equipment
Bench instruments, ATE fixtures, and module-level test systems use the A42MX16-PQG160I as a reconfigurable-at-design-time timing, sequencing, and glue-logic engine. Because MX antifuse devices require no configuration download at power-up, instruments become immediately operational when mains is applied - an operational advantage over SRAM FPGAs that spend milliseconds to tens of milliseconds loading a bitstream. The fixed routing also delivers repeatable skew from unit to unit, valuable in calibration-sensitive measurement paths. Designers implement trigger synchronization, counter/timer arrays, and interface adaptation within the 608-cell fabric.
Empfohlen
Medical Device Control Logic
Diagnostic and laboratory medical equipment often requires long-lifecycle, fixed-function control logic with predictable behavior for regulatory documentation. The A42MX16-PQG160I's one-time-programmable antifuse fabric guarantees the shipped design cannot be altered in the field, simplifying change-control audits, while industrial temperature rating and very low static power suit portable and cart-based instruments. The 125 user I/O integrate front-panel controls, motor drivers, and sensor interfaces on one chip. Fixed antifuse routing yields unit-to-unit timing repeatability that eases verification and regulatory submission of the digital control section.

- Configuration security vs SRAM FPGAs (vs. Any SRAM-based FPGA)
Designhinweise
The A42MX16-PQG160I runs from a nominal 5V supply (4.5V to 5.5V range per Mouser data). Antifuse fabrics draw near-zero static configuration current, so total dissipation is dominated by dynamic switching and I/O loading. Estimate: with heavy simultaneous I/O switching at 5V and 103 MHz-class internal clocks, budget several hundred milliwatts; verify with the Libero SoC power estimator using your actual netlist. Per the family datasheet, maximum junction temperature is 150C and allowable dissipation is a function of theta-JA - provide solid ground planes under the PQFP for heat spreading.
Antifuse MX devices are one-time programmable: unlike SRAM FPGAs there is no design iteration by re-flashing in-system. Always validate your design in simulation and, if possible, on a lower-cost or carrier-board part before committing production devices to the programmer. Reserve programming access in your fixture; after programming, the die is permanently fixed and a logic change requires a new device. Also confirm the temperature grade suffix (I vs commercial) matches your environment - commercial-grade A42MX16-PQG160 variants are not rated below 0C.
The PQG160 PQFP uses a 0.65 mm pin pitch with gull-wing leads. Use a standard QFP-160 footprint with solder-mask-defined pads per the mechanical drawing in datasheet DS2316, and verify land pattern dimensions against IPC-7351 calculations during layout. Place 0.1 uF ceramic decoupling capacitors at all VCC/GND pin pairs, distributed around the package perimeter rather than clustered at one corner. Gull-wing leads allow visual inspection and rework with standard tools; avoid repeated reflow cycles, which can degrade lead finish.
The MX family provides JTAG boundary-scan with the register chain beginning at TDI and ending at TDO per the family datasheet. Route the JTAG chain (TDI, TDO, TMS, TCK) to a standard header even in production boards - it enables board-level interconnect test and production programming. Keep TCK short and, if daisy-chaining multiple devices, series-terminate the chain drivers. Because the fabric is 5V-referenced, series resistors on fast I/O banks can reduce ground bounce in mixed 3.3V/5V systems.
Compliance-Informationen
Mouser cross-listing marks A42MX16-PQG160I as LEAD FREE; the PQG package suffix denotes the lead-free variant. Obtain current RoHS/REACH declarations from the Microchip A42MX16 product page for definitive compliance certificates.
