A42MX16-3TQG176 概要
The MX FPGA family is a line of flash-based, single-chip ASIC alternatives from Actel (now Microchip). An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that designers configure after manufacturing, positioned in the programmable logic hierarchy between CPLDs and high-end FPGAs. The MX family integrates legacy PLD designs into a single, low-cost, high-volume device.
Key features include a 5.0 V architecture with inherent tolerance for legacy 5V industrial signal environments, antifuse-style nonvolatile programming that retains configuration at power-up without an external boot PROM, and anti-tamper security since configuration data is not stored in an accessible bitstream format. The 608 CLBs and 140 I/Os provide sufficient density for glue logic consolidation, bus interfacing, and legacy ASIC replacement.
The MX architecture uses a sea-of-modules structure with combinational and sequential logic modules connected by a segmented routing fabric. Programming is performed once at programming stations, after which the device behaves as a fixed-logic ASIC, giving deterministic timing and low static power typical of antifuse/flash-based programmable devices.
Typical applications include industrial control units (ECU logic), telecom line-card glue logic, military/aerospace legacy upgrades, and consolidation of multiple PAL/GAL/PLD devices into one chip. The 5V tolerant architecture makes it particularly suited to retrofit designs built around 5V buses.
Design consideration: MX devices are one-time-programmable; verify the design in simulation and, where possible, validate on a similar-chip debugging approach before committing production units.

主な用途
A42MX16-3TQG176 の用途: 6 件s: Industrial Control / ECU Logic, Legacy ASIC / PLD Consolidation, Telecom Line-Card Glue Logic, Military / Aerospace Legacy Upgrades, Test & Measurement Fixtures, Power Sequencing and Supervision.
Industrial Control / ECU Logic
The A42MX16-3TQG176 fits industrial electronic control units where legacy 5V signal buses and deterministic, fixed-logic behavior matter. Its 5.0V CMOS MX architecture directly accepts 5V industrial I/O without level shifters, and 608 CLBs consolidate multiple PAL/GAL devices into one chip. Because the MX family is one-time programmed, logic behaves like an ASIC with deterministic timing - valuable in motor control sequencing and factory automation state machines running at up to 129 MHz internal clocks.
おすすめ
Legacy ASIC / PLD Consolidation
Microchip positions MX FPGAs as a reliable single-chip ASIC alternative for high-volume legacy integration. The A42MX16's 24,000 gates and 140 I/Os absorb retired gate arrays and multiple PLDs, cutting board area and BOM count. Since configuration is nonvolatile, the replacement requires no boot PROM, simplifying long-lifecycle maintenance of obsolete-logic systems - a common need in aerospace, rail, and utility equipment with 15-25 year service lives.
おすすめ
Telecom Line-Card Glue Logic
In telecom line cards, the A42MX16-3TQG176 provides address decoding, bus bridging, and status aggregation between processors and framers. The 176-TQFP offers 140 I/Os, enough for wide parallel buses at 5V legacy levels, while the -3 speed grade's 129 MHz capability covers timing-critical decode paths. Nonvolatile programming means cards power up instantly functional, meeting carrier requirements for rapid service restoration without configuration controllers.
おすすめ
Military / Aerospace Legacy Upgrades
The MX family is widely used to refresh obsolescent military logic boards. The A42MX16-3TQG176's one-time-programmable, anti-tamper configuration (no readable bitstream) suits defense platforms where configuration IP must be protected. Its 24K gates and 5V I/O match the electrical environment of 1990s-era MIL boards, allowing insertion without redesigning power rails. Designers validate in simulation before programming since MX devices cannot be reconfigured in the field.
おすすめ
Test & Measurement Fixtures
Bench and production test fixtures use the A42MX16-3TQG176 as fixed stimulus/response logic. The 140 I/Os drive and sense 5V DUT buses directly, and the 129 MHz speed grade handles fast handshaking. Because the design is programmed once, fixture behavior is repeatable across units and years - important for ISO-traceable production test. Combinational decode in 608 CLBs replaces racks of 74-series glue in fixture electronics.
おすすめ
Power Sequencing and Supervision
The A42MX16 can implement custom power-supply sequencing, brownout detection, and reset trees for multi-rail systems. Paired with TI regulators and supervisors from the XAIPART catalog, its 5V-tolerant I/O monitors rail divider outputs directly. One-time programming ensures the sequencing policy cannot be corrupted, a requirement in safety-related industrial equipment. Designers should account for static 5V power in thermal estimates for sealed enclosures.

主な差別化要因
- 5.0V native I/O architecture （vs A42MX16-2PQG160I (same die, PQ160 package))
- Nonvolatile one-time programming （vs Modern SRAM FPGAs (e.g., Xilinx/Altera))
- Drop-in lead-free continuity （vs A42MX16-TQG176M)
設計ノート
The MX family operates from a single 5.0V supply. Budget power using static plus dynamic estimates from the MX datasheet current tables; one-time-programmed CMOS with fixed routing gives deterministic loading. Place 0.1uF ceramic decoupling at each VDD pin pair of the 176-TQFP plus one bulk 10uF near the corner VDD pins, per standard MX family power guidance.
MX devices are one-time programmable - there is no field reconfiguration. Complete timing simulation and test-vector verification in Microchip Designer/Libero before committing devices. Do not assume SRAM-FPGA development flows apply; a design that fits in software may fail timing after routing at the -3 grade.
The 176-TQFP (24x24 mm, S-PQFP-G176) requires a 0.5 mm-class land pattern per the datasheet mechanical drawing - confirm exact pitch from the datasheet before generating the footprint. Unmatched trace lengths on wide 5V buses are generally acceptable at 129 MHz internal operation, but series-terminate long outputs to reduce ground bounce.
