A42MX16-VQG100A Descripción general
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer configures after manufacturing, sitting within the programmable logic hierarchy above SPLDs/CPLDs and below full-custom ASICs. The MX family is positioned as a reliable, single-chip ASIC alternative, ideal for consolidating legacy PLDs into one low-cost, high-volume device.
Key features include a maximum system performance of up to 250 MHz (with clock rates of 153 MHz cited for the standard grade), 5V-tolerant I/O for direct interfacing with legacy 5V logic systems, and lead-free/RoHS-compliant construction. The 0.45um technology process provides a mature, proven platform with stable, long-term availability - a key reason MX devices remain popular in defense, industrial, and automotive programs.
The MX architecture uses combinational and sequential logic modules within each cell, connected via a segmented routing fabric, supporting both glue logic consolidation and moderate-complexity system integration. Anti-fuse-free SRAM-style configuration enables reprogramming in-system.
Typical applications include legacy 5V system logic integration, industrial control, motor drive interface logic, defense/aerospace upgrade programs, and automotive subsystems requiring the A-grade temperature rating.
Design consideration: budget I/O carefully - only 83 of the 100 pins are user I/O, and 5.0V core supply requires power integrity planning; follow Microchip/Microsemi MX family datasheet decoupling guidance for reliable operation.

Aplicaciones típicas
A42MX16-VQG100A es adecuado para 6 aplicacións: Legacy 5V System Logic Integration, Automotive Subsystem Control, Defense and Aerospace Upgrades, Industrial Motor Drive Interface Logic, Test and Measurement Fixtures, Power Sequencing and Supervision Logic.
Legacy 5V System Logic Integration
The A42MX16-VQG100A's native 5.0V architecture allows it to directly replace multiple 5V TTL/CMOS PLDs, PALs, and glue-logic chips without level shifters. With 24K system gates and 83 user I/O, engineers can consolidate address decoding, bus interfacing, and control logic into one TQFP-100 device. The 0.45um process tolerates 5V I/O signaling that modern 3.3V FPGAs cannot, making this the primary migration path for maintaining older industrial equipment.
Recomendado
Automotive Subsystem Control
The A suffix of A42MX16-VQG100A designates the automotive temperature grade, targeting in-vehicle control modules that still run 5V rails. The 153 MHz system clock capability comfortably covers CAN-bus-adjacent logic, sensor preprocessing, and actuator sequencing. Its SRAM-based configuration supports field updates, while the mature process ensures supply continuity for long automotive service lives.
Recomendado
Defense and Aerospace Upgrades
MX FPGAs are widely used to refresh defense platforms where 5V backplanes and legacy signal standards persist. The related VQG100M military-grade variant shares the exact footprint with A42MX16-VQG100A, enabling one PCB design across commercial and military builds. With 608 CLBs and reprogrammable SRAM configuration, designers can retrofit modern functionality into 1980s/1990s-era avionics and ground systems.
Recomendado
Industrial Motor Drive Interface Logic
In motor drives and factory automation, the A42MX16-VQG100A implements PWM distribution, fault latching, encoder decoding, and interlock logic between a main controller and gate drivers. Its 5V I/O connects directly to legacy gate-driver enable inputs and optocoupler receiver outputs. The 250 MHz maximum device performance and deterministic FPGA timing (no software jitter) suit safety interlocks better than microcontroller firmware.
Recomendado
Test and Measurement Fixtures
Bed-of-nails testers and functional test fixtures use the A42MX16-VQG100A as a reconfigurable pattern generator and response analyzer. 83 I/O pins provide broad channel coverage, and SRAM configuration lets test engineers reload stimulus patterns per board revision. The 153 MHz clock rate covers most parallel digital interface test rates, and TQFP-100 mounting simplifies fixture rework.
Recomendado
Power Sequencing and Supervision Logic
Multi-rail systems use the A42MX16-VQG100A to implement power-good monitoring, enable sequencing, and reset distribution across 5V and legacy rails. Its immediate power-up configuration (SRAM loaded from serial EEPROM/flash) brings supervisory logic alive early in the boot chain. With 24K gates, sequencing state machines, brownout counters, and watchdog functions fit in a single device.

Diferenciadores clave
- Automotive temperature grade in standard 100-TQFP (frente a A42MX16-1VQG100)
- Native 5.0V I/O architecture (frente a Modern 3.3V FPGAs (e.g., Microchip PolarFire))
- Cost-optimized 24K gate density (frente a A42MX24-PQG160A)
Notas de diseño
The MX family operates from a single 5.0V rail. Follow the MX family datasheet decoupling recommendation: place low-ESR 0.1uF ceramic capacitors at each VDD/GND pin pair plus bulk capacitance (10-47uF) near the device. Because 83 I/O can switch simultaneously at 5V levels, ground bounce is a real concern - allocate abundant ground pins/return paths in the PCB stackup and avoid driving all I/O simultaneously at maximum slew.
The 100-pin TQFP has a 0.5mm lead pitch requiring careful solder-paste stencil design; inspect with X-ray or AOI for bridging on the fine-pitch perimeter. Keep configuration serial data lines short and away from switching I/O, since configuration corruption during power-up is a common field failure. Tie unused I/O to a defined state (input with weak pull or ground) per Microsemi design guidelines.
Do not mix MX speed grades or temperature grades when second-sourcing: A42MX16-VQG100A (automotive, standard speed) differs from -1/-2/-3 speed grades in timing closure. A bitstream meeting timing on a faster grade may fail on a slower one. Re-run timing analysis in Libero SoC whenever the suffix changes, and verify the configuration source device supports the MX serial configuration protocol.
Información de cumplimiento
Lead free / RoHS compliant per xsourcepart and PCB Electronics Supply Chain data. A suffix indicates automotive temperature grade, not formal AEC-Q100 qualification.
