MPN： A42MX16-3PQG100I ✓ 啟用中A42MX16-3PQG100I 概覽
An FPGA (Field-Programmable Gate Array) is a reconfigurable logic device that integrates thousands of programmable logic blocks and interconnects into a single chip. Within the programmable logic hierarchy (logic module -> FPGA -> programmable logic device -> semiconductor), the MX family occupies the high-reliability, single-chip ASIC-alternative niche: its antifuse programming is one-time, non-volatile, and inherently secure against readback.
Key features include an efficient 5.0 V tolerant architecture that also supports 3.3V I/O operation, making it an ideal platform for consolidating legacy 5V PLD/CPLD designs into a single low-cost device. The antifuse fabric requires no configuration PROM, boots instantly at power-up, and offers very low static power consumption compared to SRAM FPGAs.
The A42MX16 uses a 0.45 um CMOS antifuse process with a segmented routing architecture combining fast local and longer segmented lines. Microsemi's Designer software supports synthesis, place-and-route, timing analysis, and back-annotation compatible with all major simulators, cross-probed with the Silicon Explorer II verification tool.
Typical applications include glue logic integration, legacy PLD consolidation, industrial control, aerospace/defense boards requiring instant-on non-volatile configuration, and high-volume embedded systems where a single-chip ASIC alternative is needed. The industrial-grade I variant suits factory automation and instrumentation environments.
Design consideration: plan I/O banking carefully when mixing 5V and 3.3V signals, and account for the one-time-programmable nature of antifuse devices in your prototyping flow - verify designs in simulation thoroughly before programming.

典型應用
A42MX16-3PQG100I 適用於 6 應用s: Legacy PLD Consolidation, Industrial Automation Control, Aerospace and Defense Boards, Single-Chip ASIC Alternative, Test and Measurement Instrumentation, Networking and Interface Glue Logic.
Legacy PLD Consolidation
The A42MX16-3PQG100I's 5V-tolerant 3.3V/5V architecture makes it the standard choice for replacing multiple legacy PLDs, PALs, and GALs with a single device. Its 24K system gates and 83 user I/Os absorb several discrete programmable logic parts, cutting board area and BOM count. Because the antifuse fabric is instant-on and needs no configuration PROM, system power-up behavior matches the legacy discrete parts it replaces, simplifying qualification of existing designs.
推薦
Industrial Automation Control
With the industrial -40C to +85C temperature grade, the A42MX16-3PQG100I withstands factory floor temperature extremes where commercial-grade logic fails. The 142/237 MHz internal performance comfortably handles state machines, encoders, and I/O expansion logic, while 5V tolerance allows direct interfacing with legacy 24V-logic-buffered and 5V TTL sensor interfaces common in PLC backplanes. Non-volatile antifuse configuration means the controller restarts deterministically after power loss with no bootloader delay.
推薦
Aerospace and Defense Boards
Actel/Microsemi antifuse FPGAs are a mainstay of defense and aerospace designs due to configuration readback security, immunity to configuration upsets, and instant-on operation. The A42MX16-3PQG100I's 24K gates implement interface bridges, bus controllers, and mission logic, while the M-suffix sibling (A42MX16-1PQG100M) provides screened variants for military programs. Design security is inherent: the programmed antifuse network cannot be dumped, protecting intellectual property in deployed systems.
推薦
Single-Chip ASIC Alternative
The MX family is positioned by Microchip as a reliable, single-chip ASIC alternative for high-volume products. Compared to an ASIC's NRE and 20+ week lead times, the A42MX16-3PQG100I goes from HDL to programmed device in days using Microsemi Designer software, at unit costs practical in volume. The 0.45 um antifuse process delivers ASIC-like security and determinism with no configuration device, making it suitable for medium-complexity products needing 24K gates without custom silicon economics.
推薦
Test and Measurement Instrumentation
Instrumentation backplanes frequently mix 5V TTL and 3.3V logic domains; the A42MX16-3PQG100I's 5V-tolerant I/O eliminates level-shifting overhead. The -3 speed grade at 142/237 MHz supports counter/timer, trigger, and sequencer logic, while deterministic instant-on antifuse configuration ensures instruments power up into a known state immediately. The 83 I/Os handle parallel data acquisition interfaces that would exhaust smaller CPLDs.
推薦
Networking and Interface Glue Logic
The A42MX16-3PQG100I bridges legacy bus interfaces (ISA-like parallel buses, 5V backplanes) to modern 3.3V microcontrollers and processors. Its dual-voltage I/O tolerates direct 5V connections, and the -3 speed grade sustains the timing of 25-50 MHz bus protocols with margin. Because it is one-time programmable, interface logic is fixed at manufacturing, avoiding the configuration corruption risks that flash-based CPLDs face in electrically noisy networking environments.

主要差異化特點
- Industrial temperature grade at fastest speed grade (對比A42MX16-3PQG100)
- Fastest -3 speed grade in the PQ100 family (對比A42MX16-1PQG100)
- 5V-tolerant I/O rare in modern FPGAs (對比A42MX09-2PQG100I)
設計說明
The A42MX16 requires both a core supply and I/O supply consistent with the 3.3V/5V dual-voltage architecture. Decouple each VCC pin with at least 0.1uF ceramic capacitors placed within 5 mm of the pin, plus bulk 10uF capacitance per supply domain. Antifuse FPGAs have near-zero configuration current at power-up, but dynamic current scales with toggle rate - use Microsemi Designer power estimation for your actual netlist before sizing regulators.
The 100-pin PQFP has 0.65 mm lead pitch; use JEDEC-compliant PQFP-100 land patterns with slight lead extension to improve solder joint reliability. Route the 83 user I/Os with controlled impedance where bus timing matters, and keep the 5V and 3.3V I/O banks clearly partitioned in layout to simplify mixed-voltage decoupling. PQFP leads are prone to coplanarity issues - inspect with optical alignment tools before reflow.
Antifuse FPGAs are one-time programmable: you cannot erase and reprogram the device. Fully verify the design in simulation and timing analysis using Microsemi Designer before committing hardware. Also remember that a design meeting timing on a -3 grade may not close timing on -1 or -2 speed-grade substitutes, so do not substitute speed grades without re-running timing verification. Honor the -40C to +85C industrial rating - commercial-grade siblings are not qualified below 0C.
