A42MX16-TQG176A Обзор
An FPGA (Field-Programmable Gate Array) is a class of programmable logic IC whose interconnect and logic functions are configured by the designer after manufacturing, occupying the middle of the programmable-logic hierarchy between simple CPLDs and high-density system-on-chip FPGAs. The MX family is positioned as a reliable, single-chip ASIC alternative, built on 0.45 um flash/antifuse-backed technology for high-volume, cost-sensitive designs and legacy PLD integration.
Key features include the efficient 5.0V MX architecture that directly interfaces with legacy 5V logic without level shifting, 153 MHz system speed for moderate-performance sequential designs, and a compact yet thermal-friendly TQFP-176 footprint with 0.5 mm pitch leads suitable for standard surface-mount assembly. The A grade suffix indicates automotive quality screening, supporting extended-reliability transportation and industrial programs.
Technically, the MX fabric combines combinational and sequential modules with dedicated routing, allowing designers to consolidate multiple legacy PLDs, glue logic, and state machines into one low-cost device while preserving pinout stability across the A42MX09/A42MX16/A42MX24/A42MX36 family members.
Typical applications include industrial automation controllers, transportation and automotive subsystems, motor-drive sequencing, legacy MIL/AERO logic upgrades, and high-volume embedded control boards that need deterministic single-chip logic at low unit cost.
When designing with this device, verify the 5V supply rail integrity and decouple VCC/VPP per the Microsemi 40MX/42MX datasheet (DS2136/DS2316); also confirm programmer compatibility (Silicon Sculptor / FlashPro family tooling) early in the project.

Типичное применение
A42MX16-TQG176A подходит для 6 применениеs: Industrial Automation Controllers, Automotive and Transportation Subsystems, Legacy PLD Consolidation and Migration, Aerospace and Defense Logic Upgrades, Motor Drive and Power Sequencing, Embedded Control and Test Equipment.
Industrial Automation Controllers
The A42MX16-TQG176A fits industrial controller boards that must bridge legacy 5V PLC I/O with newer digital subsystems. Its native 5V MX architecture with 140 user I/Os eliminates level translators on TTL backplanes, while 608 logic cells and 153 MHz capability handle state machines, sequencing, and interlock logic. Consolidating several PLDs into one device cuts BOM count; the antifuse fabric retains configuration through power loss and industrial vibration without external configuration memory.
Рекомендуется
Automotive and Transportation Subsystems
With its automotive A-grade screening, the A42MX16-TQG176A is targeted at transportation electronics such as body-control auxiliary logic, gateways, and powertrain support boards. The 5V tolerant architecture interfaces directly with automotive 5V sensor and actuator signaling, and 153 MHz performance covers CAN framing glue, PWM generation, and safety interlocks. Its one-time-programmable fabric removes configuration-readback security concerns valued in vehicle platforms with long service lifetimes.

Legacy PLD Consolidation and Migration
The MX family was designed explicitly to integrate legacy PLDs into a single, low-cost device. Designers map multiple 22V10-class PLDs, counters, and glue logic into the A42MX16's 608 cells while keeping the existing 5V board environment unchanged. The 176-TQFP footprint stays pin-stable across A42MX09/16/24/36 densities, so a design can grow or shrink on the same PCB. This makes the part a deterministic ASIC alternative for end-of-life component redesigns and obsolescence management programs.
Рекомендуется
Aerospace and Defense Logic Upgrades
The MX family's military (M grade) variants and radiation-tolerant heritage make the A42MX16-TQG176A relevant for defense board refresh programs. Although this A-grade unit targets automotive screening, the same TQ176 footprint is shared with TQG176M military parts, enabling common layouts across commercial and defense builds. The 5V architecture matches MIL-standard TTL signaling, and antifuse retention survives harsh environments without configuration devices - a common requirement in avionics upgrades.
Рекомендуется
Motor Drive and Power Sequencing
Motor controllers benefit from the A42MX16's deterministic fabric for PWM generation, dead-time insertion, fault latching, and gate-driver sequencing at up to 153 MHz internal performance. Its 140 I/Os fan out to multiple gate drivers and current-sense comparators without external glue logic, and the 5V rails align with classic analog control circuits on drive boards. Because the antifuse configuration powers up instantly, drive outputs are defined immediately at power-on without configuration delay.
Рекомендуется
Embedded Control and Test Equipment
Bench and rack test instruments use the A42MX16-TQG176A for timing generators, trigger matrices, and bus interface glue between legacy 5V measurement front ends and modern controllers. The 176-TQFP provides enough I/O for relay control arrays, front-panel interfaces, and parallel data capture. Its low unit cost in volume makes it attractive for instrument product lines spanning decades, and the Microchip Libero toolchain plus Silicon Sculptor programming keeps rework and field updates tractable.

Заметки по проектированию
The MX family runs from a single 5.0V rail. Follow the Microsemi 40MX/42MX datasheet (DS2316) decoupling guidance: place low-ESR 0.1uF ceramic capacitors at each VCC pin pair plus bulk 10uF at the board entry. Program supply pins require the specified programming voltage only during Silicon Sculptor programming; in operation they follow datasheet biasing. Verify inrush on hot-plug 5V rails used in industrial backplanes.
The 176-TQFP uses 0.5 mm lead pitch - specify a solder-mask-defined footprint per IPC-7351-style QFP land patterns and keep fan-out vias at 0.3 mm drill or smaller to escape 140 I/Os on two signal layers. The device footprint is shared across A42MX09/16/24/36 TQ176 parts, so lay out the board once and populate any density - a deliberate MX-family feature for future-proofing and obsolescence management.
MX FPGAs are one-time programmable: a wrong bitstream permanently consumes a device, so always prototype before programming production trays. Because I/O placement is user-defined, cross-check every Libero pin assignment against the DS2316 TQ176 pin table before layout release. Also confirm which grade (A/M/C) your quality system requires - mixing automotive A-grade and military M-grade parts on one drawing will complicate traceability.
Native 5V CMOS output edges are fast enough to cause ringing on un-terminated long traces above roughly 10 cm; add series 22-33 ohm resistors on board-level buses. For mixed 5V/3.3V sections, use LVC-family translators rather than driving 3.3V-only inputs directly, and keep the 140 user I/Os grouped by bank to minimize crosstalk between high-activity clock routing and quiet analog-adjacent pins.
