A42MX16-2PQG208I Présentation
A field-programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that the designer wires together after manufacturing, occupying the middle of the programmable logic hierarchy between CPLDs and full ASICs. The Microchip (formerly Microsemi/Actel) MX family is a 5.0 V-tolerant antifuse-based FPGA platform positioned as a reliable, single-chip ASIC alternative for high-volume legacy PLD integration.
Key features of the A42MX16-2PQG208I include 608 configurable logic blocks (CLBs), approximately 24,000 equivalent gates, a maximum clock frequency of about 56.16 MHz for this -2 speed grade, and dual supply ranges of 3V to 3.6V and 4.5V to 5.5V supported by the MX 5.0 V architecture. The lead-free, RoHS-oriented PQG208 package suits conventional surface-mount assembly.
Technically, the MX family uses antifuse programmable interconnect, which is non-volatile and radiation-tolerant by nature: configuration is permanent at power-up, removing the need for an external configuration flash and improving SEU robustness versus SRAM FPGAs. The 42MX16 die sits mid-family, below the A42MX24 and A42MX36, sharing the same architecture and toolchain (Microchip Libero SoC).
Typical applications include legacy 5V system consolidation, industrial control glue logic replacement, aerospace/military program migration from obsolete PLDs, and high-volume embedded control where single-chip ASIC cost is not justified.
Design consideration: the 208-PQFP 28x28 mm body requires careful fanout; the industrial -40C to +85C rating of the I suffix must be preserved by keeping junction temperature within limits given the FPGA's static and I/O current.

Applications typiques
A42MX16-2PQG208I convient pour 6 applications: Legacy 5V System Consolidation, Industrial Control and Automation, Aerospace and Defense Program Sustainment, ASIC Prototyping and Bridge Logic, Medical Equipment Legacy Boards, Communication and Networking Interface Cards.
Legacy 5V System Consolidation
The A42MX16-2PQG208I's 5.0 V-tolerant MX architecture with 3V-3.6V and 4.5V-5.5V supply ranges lets engineers collapse multiple obsolete PLDs, PALs, and glue-logic devices into one antifuse FPGA without level-shifting on 5V buses. Its 24,000 gates and 140 user I/O cover typical multi-device consolidation, while non-volatile antifuse configuration gives instant-on behavior identical to the discrete parts being replaced. This makes it a low-risk migration path for industrial equipment and test instruments still running legacy rails, per Microchip's MX positioning as a single-chip ASIC alternative.
Recommandé
Industrial Control and Automation
In factory automation and process control, the A42MX16-2PQG208I provides deterministic, configuration-fixed logic for sequencing, interlocking, and interface translation. The industrial -40C to +85C rating, 5V-tolerant I/O for sensors and actuators, and instant-on antifuse startup eliminate boot-time gaps that SRAM FPGAs introduce after power loss. The -2 speed grade's ~56.16 MHz capability comfortably covers state machines and bus interfaces in this domain. Its permanence of configuration also simplifies functional-safety arguments where unintended reconfiguration is unacceptable on the plant floor.
Recommandé
Aerospace and Defense Program Sustainment
Microchip MX antifuse FPGAs are widely used to sustain defense and aerospace platforms because the technology is inherently single-event-upset tolerant - configuration is hard-wired, not stored in volatile cells. The pin-compatible CQ208 ceramic package screened toward MIL-STD-883 levels allows plastic PQ208 prototypes to convert directly to qualified ceramic production parts without board redesign, as stated in the Microchip datasheet. For programs locked to the A42MX16 die, the A42MX16-2PQG208I supports industrial-temperature prototype builds ahead of ceramic qualification runs.
Recommandé
ASIC Prototyping and Bridge Logic
The A42MX16-2PQG208I serves as a low-cost ASIC alternative for mid-volume products where mask costs cannot be justified, and as bridge logic between mismatched bus standards on mixed-voltage boards. Its antifuse fabric provides fixed timing after programming - useful when validating interfaces destined for ASIC conversion - and the 208-PQFP's 0.5 mm pitch is hand-solderable for lab rework. Designers typically implement bus bridges, address decoders, and custom peripherals within the 24K-gate budget, migrating to the pin-compatible A42MX36 PQ208 parts when gate count grows.
Recommandé
Medical Equipment Legacy Boards
Medical device manufacturers maintaining long-lifecycle equipment use the A42MX16-2PQG208I to keep obsolete control boards in production without recertification of the whole system. The non-volatile antifuse configuration preserves deterministic power-up behavior required by patient-connected equipment, while industrial temperature rating covers clinical environments. Because the part is still active from Microchip and shares the MX architecture across A42MX16/A42MX36 PQ208 members, last-time-buy risk is mitigated by documented pin-compatible successors on the identical footprint.
Recommandé
Communication and Networking Interface Cards
On line cards and protocol adapters, the A42MX16-2PQG208I implements framing, formatting, and backplane glue logic with 5V-tolerant I/O that connects directly to legacy backplanes. The 140 user I/O accommodate wide parallel buses, and the fixed antifuse routing delivers repeatable signal timing across units - important for multi-slot systems. The -2 speed grade supports interface clock rates within the family's ~56 MHz class. For higher-throughput designs, the same-footprint A42MX36 parts double the logic without PCB respin, protecting the layout investment.

Principaux différenciateurs
- Non-volatile antifuse configuration - no boot flash, instant-on, SEU-tolerant (vs A42MX16-PQG208I (and all SRAM FPGAs))
- 5V-tolerant dual-rail I/O architecture (vs A42MX16-1PQG208I)
- Pin-compatible gate-count upgrade without respin (vs A42MX36-2PQG208I)
Notes de conception
The MX family supports dual supply ranges (3V-3.6V and 4.5V-5.5V); identify which rail each bank uses before schematic capture and never mix them on one bank. Estimated: with 140 I/O, simultaneously switching outputs can drive tens of milliamps per bank - budget core and I/O current separately and size the 3.3V/5V regulators accordingly. Decouple each VCC/VDDA pin pair with 0.1 uF ceramics placed within 2 mm of the pin, plus bulk 10 uF per rail.
The 208-PQFP has 0.5 mm lead pitch; specify a solder-mask-defined footprint per IPC-compatible PQFP land patterns and inspect with AOI or X-ray for bridging on fine-pitch rows. Route JTAG (TCK/TMS/TDI/TDO) as a short daisy chain with series resistors near the header to limit ringing. Because antifuse parts are programmed post-assembly, keep programming-pad access or plan socketed prototypes; reprogramming is impossible after fuse blowing.
The most common MX design error is treating this like an SRAM FPGA: there is no external configuration flash and no in-field reconfiguration - each logic change consumes a new device. Order the full ordering code including speed grade and I suffix; mixing commercial-range parts into -40C applications causes field failures. Verify the -2 timing constraints in Libero rather than assuming -1 data; and for upgrade paths, design the board to the PQ208 pin map so A42MX36 PQ208 parts drop on later.
