A42MX09-TQG176A - 14K Gate 5V FPGA 176-TQFP | Microchip
MPN： A42MX09-TQG176A ✓ 啟用中A42MX09-TQG176A 概覽
An FPGA (field programmable gate array) is a semiconductor device configurable after manufacture via a hardware description language such as Verilog or VHDL. FPGAs sit within the broader taxonomy of programmable logic devices, which also includes CPLDs and SPLDs, and the MX family is specifically positioned as a single-chip ASIC alternative for high-volume legacy integration.
Key features include the efficient 5.0V MX architecture, which tolerates industrial noise margins and directly interfaces with 5V legacy logic without level shifting. The MX family uses Actel antifuse-based one-time programmable technology, providing a reliable, single-chip ASIC alternative, secure design protection against bitstream readback, and no external configuration PROM requirement. The TQFP-176 package offers 104 user I/O and 0.65 mm pin pitch for surface-mount assembly.
Architecturally, the A42MX09 combines combinatorial and sequential modules in Actel's C-Module and R-Cell structure, achieving predictable routing delays suited to 5V industrial control and embedded glue logic. With 336 cells and a 192 MHz maximum toggle performance, the device integrates multiple legacy PLDs, state machines, and address decoders into one low-cost package.
Typical applications include industrial automation controllers, legacy 5V system redesigns, motor control interfaces, test equipment, and avionics/defense platforms where one-time-programmable reliability and design security are valued. The automotive/industrial grade suffix A indicates extended screening per Microchip's A42MX datasheet (Actel MX FPGA family).
Design consideration: the MX family is one-time programmable (OTP), so functional errors cannot be fixed after programming; thoroughly simulate with Libero/Microsemi toolchains before committing hardware, and verify 5V power sequencing and decoupling on all VCC pins.

典型應用
A42MX09-TQG176A 適用於 6 應用s: Industrial Automation Controllers, Legacy PLD Consolidation, Avionics and Defense Systems, Motor Drive and Power Control, Test and Measurement Equipment, ASIC Prototyping and Low-Volume Bridge Logic.
Industrial Automation Controllers
The A42MX09-TQG176A fits industrial controller designs because its native 5.0V architecture interfaces directly with legacy 24V-zone I/O buffers, 5V sensors, and PLD replacement targets without level shifting, while 104 user I/O provide ample parallel interface density. In a controller board it typically implements state machines, address decoding, and motor drive sequencing at deterministic speeds up to 192 MHz. Because MX antifuse logic is non-volatile and OTP, no configuration PROM or boot delay occurs, improving power-up reliability in factory environments.
推薦
Legacy PLD Consolidation
The MX family is explicitly marketed by Microchip as an ideal platform for integrating legacy PLDs into a single, low-cost device, and the A42MX09-TQG176A's 14K gates and 336 cells provide capacity to replace multiple 22V10-class PALs and small CPLDs on one chip. In consolidation projects the antifuse OTP technology preserves the deterministic, non-configurable behavior of the original glue logic, while 192 MHz performance exceeds legacy device speeds. This reduces board area, BOM count, and procurement risk for long-life industrial and defense platforms.
推薦
Avionics and Defense Systems
Defense and avionics programs value the A42MX09-TQG176A's one-time-programmable antifuse fabric, which provides inherent design security - there is no bitstream to read back, unlike SRAM FPGAs - plus immunity to configuration upsets at power-on. M-grade siblings such as the A42MX09-1TQG176M cover military screening flows. With 5V noise-robust I/O, 14K gates for interface glue logic, and a long-lifecycle platform from Microchip (Microsemi), the device suits radar interfaces, missile electronics, and space-adjacent ground equipment needing dependable, non-volatile programmable logic.
推薦
Motor Drive and Power Control
In 5V motor drive systems the A42MX09-TQG176A generates PWM sequences, dead-time logic, and fault interlocks with deterministic timing thanks to the antifuse fabric's fixed delays, while its 5V I/O directly drives gate-driver input buffers common on legacy motor boards. The 104 user I/O accommodate encoder inputs, hall sensors, and parallel fault buses in one package. Since MX logic is OTP, safety interlock configurations cannot be corrupted at runtime - an advantage for drive systems where predictable behavior at power-up is a certification concern.
推薦
Test and Measurement Equipment
Bench and automated test instruments use the A42MX09-TQG176A for parallel pattern generation, address generation, and scan-chain glue logic, exploiting 192 MHz toggle capability and 104 parallel I/O. The 5.0V fabric matches the TTL-level signaling still common in instrumentation backplanes, eliminating translators. OTP antifuse configuration ensures the instrument powers up with the correct function immediately, avoiding the boot delay of SRAM FPGAs. Its TQFP-176 surface-mount package supports compact instrument motherboards with standard 0.65 mm pitch assembly processes.
推薦
ASIC Prototyping and Low-Volume Bridge Logic
The Microchip MX family is positioned as a reliable single-chip ASIC alternative, making the A42MX09-TQG176A practical for ASIC interface bridging, bus conversion, and low-volume production where an ASIC mask set is uneconomical. Its 14K gates suit handshake, FIFO, and protocol adaptation logic between processors and peripherals. The 5V-tolerant, 104-pin I/O bank simplifies interfacing with legacy buses, and the non-volatile antifuse fabric removes configuration controllers from the BOM. As of 2026 the family remains supported in Microchip Libero design flows.

主要差異化特點
- Larger logic capacity in same footprint (對比A42MX16-TQG176M)
- Lead-free RoHS finish (對比A42MX09-TQ176A)
- Non-volatile OTP fabric with no boot delay (對比SRAM FPGAs (cross-brand))
設計說明
The A42MX09 operates from a single 5.0V rail. Decouple every VCC pin with 0.1 uF ceramic capacitors placed within 2 mm of the pin, and add bulk 10 uF capacitance near the package corner VCC/ground pairs. Because MX antifuse FPGAs draw low static current, dynamic switching on parallel I/O dominates; add per-bank decoupling when driving heavy 5V bus loads to limit ground bounce.
The MX family is one-time programmable (antifuse). Unlike SRAM FPGAs, a functional bug cannot be corrected after programming - the device is consumed. Run full RTL simulation and timing closure in the Microchip (Actel) Libero toolchain, and verify pin assignments against the MX family datasheet package tables before sending a device to programming. Reserve engineering budget for at least one re-spin of programmed parts.
The 176-TQFP has a 0.65 mm lead pitch; specify a solder mask-defined land pattern per the Microchip package drawing with slightly elongated pads to aid inspection. Keep 5V-to-noisy-switcher routing away from I/O banks feeding 5V legacy logic, and use a solid ground plane to return the switching currents of the 104 I/O. Thermal load is modest at 14K gates, so standard 2-ounce copper plane suffices - no heatsink is required.
