A42MX16-3VQG100 Обзор
An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of programmable logic blocks and reconfigurable interconnects that designers configure in the field after manufacturing. Within the device hierarchy, the A42MX16 sits in the FPGA family under programmable logic ICs, which in turn belong to the broader category of digital integrated circuits and semiconductors. Unlike SRAM FPGAs, the MX family uses a reliable, non-volatile architecture, making it a true single-chip ASIC alternative.
Key features include the efficient 5.0 V MX architecture that eliminates the need for a separate configuration device, 24K system gates suitable for glue logic consolidation, and legacy PLD integration on a single low-cost platform. The MX family is specifically positioned by Microchip as a high-volume platform for integrating legacy PLDs into one device, reducing board area, BOM cost, and assembly complexity.
Technically, the device contains 608 CLBs organized with dedicated flip-flops and combinational logic resources. The -3 speed grade supports up to 129 MHz maximum toggle rates, sufficient for legacy bus interfaces, state machines, address decoders, and control logic. The 5.0 V tolerant I/O structure enables direct interfacing with 5V TTL-era systems without level translation, a key reason this family remains in production for legacy designs.
Typical applications include legacy PLD consolidation, industrial control, 5V bus bridging, military/aerospace program sustainment, and high-volume ASIC replacement where non-volatile, single-chip operation is required.
Design consideration: the MX family operates from a 5.0 V supply, so level-shifting is required when interfacing with 3.3V or 2.5V logic; plan decoupling and power-rail design accordingly.

Типичное применение
A42MX16-3VQG100 подходит для 6 применениеs: Legacy PLD Consolidation, Industrial Control Systems, 5V Bus Bridging and Interface Logic, Military and Aerospace Sustainment, ASIC Prototyping and Low-Volume ASIC Replacement, Instrumentation and Test Equipment.
Legacy PLD Consolidation
The A42MX16-3VQG100's 24K system gates and 608 CLBs let designers replace multiple 22V10-class PAL/GAL devices and small CPLDs with one non-volatile chip. Because the MX architecture operates at 5.0 V, existing 5V TTL board designs can be consolidated without level-shift ICs, cutting BOM count, board area, and assembly cost. The 83 user I/Os cover typical multi-PLD I/O counts, and the -3 speed grade at 129 MHz handles legacy bus timing with margin. Non-volatile configuration means no boot device or power-up configuration delay.

Industrial Control Systems
In industrial controllers, the A42MX16-3VQG100 implements state machines, address decoding, and interface glue logic at up to 129 MHz with a 5.0 V supply tolerant of electrically noisy environments. The non-volatile MX fabric is single-chip and immediately active at power-up, important for equipment requiring deterministic startup without configuration time. The 100-pin VQFP with 0.5 mm pitch is hand-reworkable for low-volume industrial maintenance. Microchip positions MX as a high-volume, low-cost platform suited to long-life industrial product lines.

5V Bus Bridging and Interface Logic
Many legacy backplanes, VME-style buses, and instrumentation interconnects run 5.0 V TTL signaling. The A42MX16-3VQG100's native 5V I/O connects directly to these buses, replacing discrete transceivers, decoders, and sequencers with 24K gates of programmable logic. The -3 speed grade supports 129 MHz internal operation, comfortably above common legacy bus clock rates, while the 83 I/Os map to wide 32-bit data and address paths. Designers avoid dual-supply level translators entirely, improving noise margin and reliability.

Military and Aerospace Sustainment
MX FPGAs are used across military and aerospace legacy programs where design continuity matters more than leading-edge density. The A42MX16-3VQG100M military-grade variant of the same die offers extended screening, while the commercial -3VQG100 supports ground-based and benign-environment equipment. Non-volatile single-chip operation eliminates configuration upset risks in harsh power environments, and Microchip's long-term manufacturing commitment to MX supports 10-20 year program sustainment. The 24K gate capacity covers typical avionics glue logic, sequencers, and bus interface functions.
Рекомендуется
ASIC Prototyping and Low-Volume ASIC Replacement
Microchip markets MX as a reliable single-chip ASIC alternative. The A42MX16-3VQG100's 24K gates suit low-volume ASIC replacements such as custom decoders, protocol handlers, and controller chips where mask ASIC NRE is unjustified. Non-volatile programming removes configuration devices required by SRAM FPGAs, matching the single-chip ASIC footprint. At 129 MHz maximum clock, the device covers many legacy ASIC timing budgets, and the 0.5 mm pitch VQFP simplifies assembly for prototype and low-volume production runs.
Рекомендуется
Instrumentation and Test Equipment
Bench and automated test instruments frequently mix 5V legacy interfaces with custom sequencing and trigger logic. The A42MX16-3VQG100 provides 24K gates of non-volatile logic with 83 I/Os for trigger chains, scaler logic, and bus interfaces, all at a 5.0 V supply matching legacy instrument architectures. Its 129 MHz -3 speed grade supports fast trigger propagation, and the deterministic power-up behavior of non-volatile MX fabric eliminates configuration latency in time-critical measurement setups. The TQFP-100 footprint fits dense instrument PCBs with standard SMT assembly.

Заметки по проектированию
The MX family operates from a single 5.0 V supply. Provide local decoupling of at least 0.1 uF ceramic per VDD pair plus bulk 10 uF per rail. Because the non-volatile MX fabric draws inrush-free current at power-up, no soft-start sequencing is needed - a benefit over SRAM FPGAs that must configure after supply ramp.
The 5.0 V I/O banks drive legacy TTL loads directly, but fast -3 grade edges into long backplane traces can cause ringing. Series terminate (22-33 ohm) long lines and maintain solid ground return. When interfacing to 3.3V-only devices, use proper level shifters - MX I/O must not be overdriven below its 5V-referenced thresholds.
Speed grades are not interchangeable without timing verification: a -1 or -2 part substituted for a -3 may fail 129 MHz-class timing paths. Run timing analysis in Libero/Designer after any grade change. Also confirm ordering-code temperature suffix (commercial, I, or M) against the system environment before purchase.
Информация о соответствии
[DATA_NEEDED: RoHS/REACH/lead-free status from Microchip product page] - the G suffix in the ordering code typically denotes green/lead-free packaging, but this must be confirmed against official Microchip compliance documentation.
