A42MX16-3PQG160 Обзор
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer wires together post-manufacture, sitting within the broader hierarchy of programmable logic devices (PLDs -> CPLDs -> FPGAs -> programmable SoCs). The MX family was explicitly positioned by Microsemi as a low-cost, high-volume platform for consolidating legacy PLD designs into a single device.
Key features include the efficient MX antifuse architecture, which is non-volatile and radiation-tolerant by nature of its one-time-programmable interconnect, and support for IEEE 1149.1 JTAG boundary-scan testing across the 40MX/42MX families per the Microsemi DS2136 family datasheet. The -3 speed grade is the fastest commercial grade of the A42MX16 device, supporting higher clock frequencies than -1 and -2 grades within the same package footprint.
The device is fabricated in CMOS technology and integrates seamless support for common bus and memory interfaces typical of embedded control, industrial automation, and communications bridge logic. Because the MX fabric is a mature, stable platform, designs locked into this family can rely on long-term sourcing continuity through Microchip Technology.
Typical applications include legacy PLD consolidation, industrial motor control glue logic, telecommunications line-card control, and avionics/defense systems that leverage the antifuse fabric's inherent single-event-upset immunity.
Design consideration: the MX family requires programming via the Actel/Microchip programming flow (Designer software), and because antifuse devices are one-time-programmable, verify the complete design in simulation before committing hardware. Confirm exact speed-grade timing and supply parameters against the official 40MX/42MX family datasheet DS2316 before production release.

Типичное применение
A42MX16-3PQG160 подходит для 6 применениеs: Legacy PLD Consolidation, Industrial Automation Control, Telecommunications Line Cards, Defense and Avionics Logic, ASIC Prototyping and Bridge Logic, Test and Measurement Equipment.
Legacy PLD Consolidation
The MX family was designed by Microsemi specifically to integrate legacy PLD, PAL, and GAL designs into a single low-cost device. The A42MX16-3PQG160's 24,000 system gates and 608 CLBs provide enough capacity to absorb multiple older 22V10-class devices plus surrounding glue logic, reducing board area and BOM line items. The antifuse fabric programs once and retains configuration permanently with no boot-time load, matching the instant-on behavior of the PLDs it replaces in industrial control panels and line cards.
Рекомендуется
Industrial Automation Control
In factory automation and motor control panels, the A42MX16-3PQG160 implements address decoding, interrupt arbitration, PWM fan-out, and sensor interface glue logic. Its 125 user I/O connect encoders, limit switches, and communication transceivers, while the -3 speed grade supports the fastest decode paths of the family. Because the antifuse configuration is immune to configuration-memory upset, the device powers up deterministic at every cycle - a key requirement for safety-adjacent control sequences in PLC backplanes.
Рекомендуется
Telecommunications Line Cards
Telecom line cards historically relied on MX antifuse FPGAs for framing logic, backplane interfaces, and TDM bus bridging. The A42MX16-3PQG160 provides 24K gates for channel-count logic and IEEE 1149.1 JTAG for board-level production test, both essential in NEBS-style card designs. The mature CMOS process and stable, non-changing MX fabric mean designs verified years ago remain bit-identical through continued production, avoiding the requalification churn typical of SRAM FPGA fabric updates.
Рекомендуется
Defense and Avionics Logic
Antifuse FPGAs are favored in defense and avionics payloads because their one-time-programmed interconnect contains no configuration memory that can be disturbed by radiation-induced single-event effects. The A42MX16-3PQG160's 24K gates suit telemetry formatting, bus interface adaptation, and voter/comparator logic. The non-volatile fabric also removes the need for external configuration flash, reducing parts count and improving startup determinism in mission-critical systems subject to long program lifecycles.
Рекомендуется
ASIC Prototyping and Bridge Logic
The MX family is positioned by Microchip as a reliable single-chip ASIC alternative, and the A42MX16-3PQG160 fills this role for low-to-medium volume ASIC replacements. Its 24,000 gates accommodate state machines, address generators, and protocol converters, while the -3 grade provides the fastest available timing within the family. Because the fabric is mask-programmed-equivalent once programmed, it avoids the configuration-stream security concerns of SRAM FPGAs in proprietary bridge-logic designs.
Рекомендуется
Test and Measurement Equipment
Bench instruments and automated test fixtures use the A42MX16-3PQG160 for trigger distribution, timing generation, and fixture-specific adaptation logic. Its 125 I/O drive relay matrices and comparator banks, and JTAG boundary scan simplifies in-fixture self-test. The fixed antifuse routing keeps propagation delays deterministic, which matters for trigger skew budgets; the -3 speed grade minimizes worst-case path delay within the MX16 density point.

Ключевые отличия
- Fastest speed grade in the A42MX16 family (против A42MX16-2PQG160)
- Non-volatile antifuse fabric (против SRAM-based competitor FPGAs)
- JTAG boundary scan (IEEE 1149.1) (против A42MX16-2PQG160 (same feature, but -3 timing margin))
Заметки по проектированию
The MX fabric is one-time programmable antifuse - the design cannot be changed after programming. Complete gate-level simulation and static timing closure in Microchip Designer (Actel Designer) before submitting the device to programming, and order engineering lots accordingly. Do not rely on in-field firmware updates as with SRAM FPGAs.
Verify the exact VCC specification for the -3PQG160 ordering code against datasheet DS2316 before board design; MX family marketing cites a 5.0 V architecture while A42MX16 CMOS die data cites 3.0V-3.6V operation with 3.3V nominal. Decouple each VCC pin with 0.1 uF ceramics placed within 2 mm of the PQFP supply pins.
With 125 user I/O on a 0.635 mm pitch PQFP, limit the number of simultaneously switching outputs per ground return by spreading I/O assignment across banks and adding series 22-33 ohm resistors on fast edges. Use IEEE 1149.1 JTAG chain access for production test of the surrounding board instead of bed-of-nails probing.
The PQFP-160 footprint with 0.635 mm pitch requires fine-pitch PCB capability (typically 6/6 mil minimum). Design the land pattern per the Microchip PQG160 mechanical drawing in DS2316 and keep the -3 grade's faster edges in mind when routing clock lines - keep clock traces short and reference a solid ground plane.
