A42MX16-1TQG176M Übersicht
An FPGA is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer programs to implement custom digital logic. Within the programmable logic hierarchy, the MX family sits as a low-cost, high-volume programmable logic platform, an alternative to fixed ASICs and legacy PLD consolidation. The 42MX subfamily is built on a 0.45 um process with a flexible architecture that supports dual supply domains of 3.0V to 3.6V and 4.5V to 5.5V, which is unusual among FPGAs and directly addresses legacy 5V system integration.
Key features include 24K system gates with 608 logic cells, 140 programmable I/O pins with gull-wing terminations, dual-voltage operation (3.3V core-compatible and 5V tolerant system rails), and military temperature grading (-55C to +125C TC) making the device suitable for defense and aerospace programs. The -1 speed grade provides 119 MHz/198 MHz timing performance, and the M suffix denotes the military screening flow.
Architecturally, the MX family uses Microsemi's proven act-module fabric with combinational and sequential modules, dedicated flip-flops, and embedded boundary-scan (JTAG, TDI-TDO chain) programming support per the 40MX/42MX families datasheet. The single-chip ASIC-alternative positioning allows designers to integrate legacy PLD, glue logic, and state machines into one low-cost device without NRE charges.
Typical applications include military and avionics glue logic, industrial control, legacy 5V system upgrades, communication interface bridging, and high-reliability embedded controllers where long-term availability and wide temperature operation matter more than cutting-edge density.
Design consideration: the dual supply ranges require careful power-rail sequencing and decoupling; verify the 0.45 um process timing derating across the full military temperature range using the -1 speed grade figures in the manufacturer datasheet.

Military and Avionics Glue Logic
The A42MX16-1TQG176M is purpose-built for defense and avionics subsystems because it combines the M-suffix military screening (-55C to +125C TC) with a proven 0.45 um process immune to deep-submicron radiation and reliability concerns. Its 24K system gates and 608 cells absorb address decoders, bus interfaces, state machines, and legacy PLD functions that previously consumed multiple 5V logic devices. The 140 user I/O pins interface directly to 5V and 3.3V backplane signals thanks to the dual 3V-3.6V / 4.5V-5.5V supply ranges, eliminating level-shift circuitry that modern 1.2V-core FPGAs would require. ROHS3 compliance permits use in mixed commercial-military platforms, and the 20-week factory lead time is offset by distributor stock for program sustainment.

Legacy 5V System Integration
The MX family is explicitly positioned by Microchip as an efficient, flexible 5.0V architecture for integrating legacy PLDs into a single low-cost device, and the A42MX16-1TQG176M delivers that benefit with 24K gates and dual 3V-3.6V / 4.5V-5.5V supply domains. In upgrade programs where a 5V VME, ISA-era, or industrial backplane must remain untouched, this FPGA accepts 5V signals directly, unlike modern FPGAs that need bus switches or series resistors. The 140 I/O replace several dozen TTL/PLD packages, cutting board area and failure points. Because the fabric is 0.45 um and the package is a large 24x24 mm TQFP, thermal and signal-integrity margins are generous, easing qualification of long-lifecycle industrial retrofits.
Empfohlen
Industrial Control and Automation
In factory automation controllers, motor-drive interface cards, and programmable-logic replacement modules, the A42MX16-1TQG176M provides deterministic, single-chip integration of encoders decoding, PWM generation, interlock logic, and fieldbus glue functions. The -1 speed grade toggles at 119 MHz/198 MHz, far exceeding the tens-of-megahertz needs of industrial sequencing, while the wide -55C to +125C rating covers unventilated control cabinets and outdoor encoders. The 176-TQFP's 0.5 mm-pitch gull-wing leads are compatible with standard reflow assembly, and the 608-cell fabric is programmed once and retained, avoiding configuration-flash reliability questions in electrically noisy environments. Dual-voltage operation bridges new 3.3V controller electronics to legacy 5V sensor and relay-driver rails.
Empfohlen
Communication Interface Bridging
The A42MX16-1TQG176M implements protocol bridges and interface converters between legacy serial, parallel, and backplane standards: 24K gates are sufficient for dual-UART arrays, synchronous serial framers, address/data bus multiplexing, and JTAG-controlled test-access logic. Boundary-scan cells chained from TDI to TDO, described in the 40MX/42MX families datasheet, enable board-level interconnect testing in telecom racks. The dual 3.3V/5V I/O domains connect directly to both modern line cards and legacy 5V backplanes, and the 140 I/O support wide parallel buses that pin-limited modern FPGAs cannot serve without serdes renegotiation. For systems with the military -55C to +125C envelope, the M grade removes derating compromises required with commercial parts.
Empfohlen
ASIC Prototyping and Low-Volume Replacement
Microchip positions the MX family as a reliable single-chip ASIC alternative, and the A42MX16-1TQG176M lets teams prototype or sustain gate-array-class logic (up to 24K gates, 608 cells) with zero NRE and immediate program-and-deploy turnaround. Designs captured in the MX fabric run at -1 speed grade timing (119 MHz/198 MHz toggle), adequate for control-plane and moderate-throughput datapath functions. In production-sustainment scenarios where an obsolete ASIC or gate array must be emulated, the same-package A42MX24 variants offer headroom, and the dual 3.3V/5V rails replicate the I/O signaling of 1990s-era ASICs. Tray packaging suits low-volume, high-mix defense and industrial build flows.
Empfohlen
High-Reliability Embedded Controllers
For satellite-adjacent ground equipment, test instrumentation, and railway or energy-sector controllers requiring wide temperature tolerance and long-term availability, the A42MX16-1TQG176M offers a -55C to +125C rating, ROHS3 compliance, and an active lifecycle status within Microchip's supported MX portfolio. The one-time-programmable fabric avoids configuration-readback upsets that concern SRAM FPGAs in safety-critical systems, and the generous 0.45 um process geometry provides superior total-ionizing-dose margins compared with 28 nm-class devices. The 24x24 mm TQFP dissipates little power at MX-class clock rates, typically eliminating heatsinks, and 140 I/O integrate all supervisory, interlock, and diagnostics logic in one screened component.

Designhinweise
The A42MX16-1TQG176M supports two supply domains: 3V-3.6V and 4.5V-5.5V. Determine early which domain each I/O bank uses, because the choice drives both the external rail design and the 5V-tolerance of connected circuits. Decouple each supply pin with 0.1 uF ceramic capacitors placed within 2-3 mm of the pin, plus bulk 10 uF per rail. Because the 0.45 um fabric draws modest dynamic current at MX-class clock rates, Estimated: a 140-I/O design toggling under 20 MHz typically stays well under 1W, but verify with Libero power analysis for your specific net toggle rates.
Do not mix speed grades without re-running static timing: the A42MX16-TQG176M (-0) toggles at 103 MHz/172 MHz versus 119 MHz/198 MHz for the -1 part, a roughly 14% timing reduction. Substituting a slower grade into a -1-timed design can fail marginal setup paths even though the package and pinout are identical. Also confirm temperature grade before second-sourcing: the I-suffix industrial part is not rated for the -55C to +125C military envelope of the M-suffix device, and swapping grades without program-office approval can invalidate qualification.
The 176-TQFP has 0.5 mm lead pitch gull-wing terminations on a 24x24 mm body. Use a 1:1 non-solder-mask-defined footprint per the manufacturer datasheet land pattern, with off-center thermal relief avoided under the die area. Route JTAG (TDI, TDO, TMS, TCK) as a daisy chain with series 22-33 ohm resistors on TCK to control ringback; the boundary-scan chain from TDI to TDO is used for both programming and in-system board test. Keep 5V-domain traces at least 2x dielectric width from 3.3V traces when both domains are used on the same board.
With 140 I/O available, simultaneous switching noise is the main integrity risk on wide 5V buses. Group outputs by bank, stagger switching edges in the RTL where feasible, and return every second pin position to ground in the floorplan where the pin map allows. At -1 grade toggle rates (up to 198 MHz), series termination (22-33 ohm) on clock and long parallel buses within the FPGA fabric output is a low-cost mitigation. The 0.45 um process output edges are slow by modern standards, which actually helps on legacy backplanes but limits use in modern high-speed interfaces.
