Typical Applications
A42MX16-PQG208A is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control and Automation, ASIC Prototyping and Low-Volume ASIC Replacement, Communications Interface Bridging, Military and Aerospace Upgrade Programs, Test and Measurement Equipment.
Legacy PLD Consolidation
The MX family was explicitly designed by Microchip (Microsemi) to consolidate legacy PLDs, PALs, and GALs into a single low-cost device. With 24K gates and 140 I/O, the A42MX16-PQG208A can absorb dozens of 22V10-class parts, cutting BOM count, board area, and assembly cost. Its 5.0V-tolerant I/O rail (4.5V to 5.5V supply) connects directly to legacy TTL/5V CMOS logic without level shifting, a key advantage over modern 3.3V-only FPGAs. The 0.45um process yields a stable, proven platform for long-lifecycle industrial builds.
Recommended
Industrial Control and Automation
In factory automation and industrial control, the A42MX16-PQG208A implements state machines, sensor interface glue logic, and bus arbitration with an operating range of -40C to +125C, covering harsh cabinet environments. The 140 user I/O handle parallel sensor arrays, relay drivers, and 5V PLC backplane signals directly, since the I/O rail operates at 4.5V to 5.5V. Designers place it between a microcontroller and field wiring to offload timing-critical sequencing; its deterministic CLB fabric avoids software latency. ROHS3 compliance keeps it valid in current industrial builds.
Recommended
ASIC Prototyping and Low-Volume ASIC Replacement
Microchip positions MX FPGAs as a reliable, single-chip ASIC alternative with no NRE cost, ideal for prototyping gate-array designs and for low-to-mid volume production where a mask ASIC cannot be justified. The A42MX16 die with 24,000 gates and 1232 logic cells accommodates mid-size control and datapath designs, while the 208-pin PQFP provides 140 I/O for wide data buses. Unlike SRAM FPGAs, the antifuse-class MX programming approach retains configuration at power-up without an external boot flash, simplifying BOM and improving startup determinism.
Recommended
Communications Interface Bridging
The device suits legacy communications equipment - protocol converters, backplane bridges, and line-card glue logic - where 5V signaling remains standard. With 140 user I/O and ~100 MHz-class family toggle capability (speed-grade dependent), it implements UART/SPI extensions, parallel bus translation, and framing logic. The dual-rail supply (3.3V core, 5V I/O) lets designers interface modern 3.3V controllers to 5V line interfaces in one device, eliminating discrete level translators. JTAG support on MX family devices aids board-level test per IEEE 1149.1 where applicable.
Recommended
Military and Aerospace Upgrade Programs
The 42MX family with 'M' suffix variants (e.g., A42MX24-1PQG208M) serves military platform upgrades where long availability and proven 0.45um CMOS matter more than cutting-edge density. The A42MX16-PQG208A footprint is shared across the family, letting maintenance programs scale density from 24K to 36K gates without PCB respin. Its -40C to +125C rating and tray packaging support high-reliability builds. Program managers value the stable, non-EOL-prone legacy roadmap that Microchip maintains for MX FPGA products.
Recommended
Test and Measurement Equipment
Bench and automated test equipment frequently needs custom timing, muxing, and trigger logic alongside 5V legacy instruments. The A42MX16-PQG208A implements scan controllers, trigger fan-out, and parallel handshaking with its 140 I/O directly compatible with 5V TTL instrument buses (I/O supply 4.5V to 5.5V). Deterministic CLB delays simplify setup/hold analysis against instrument timing budgets. Its active lifecycle status and 12-week lead time make it practical for equipment OEMs running long production programs with periodic reorders.

Key Differentiators
- Native 5V I/O operation (vs A42MX16-1PQG208I)
- Lowest density/cost 208-PQFP MX option (vs A42MX24-1PQG208I)
- Headroom for growth without respin (vs A42MX36-1PQG208)
Design Notes
The A42MX16-PQG208A requires two independent rails: 3.0-3.6V core and 4.5-5.5V I/O. Use a 3.3V LDO or buck for the core rail and a clean 5V rail for I/O banks. Add 0.1uF ceramic decoupling at every VCC/VCCI pin pair plus bulk 10uF per rail. Follow power-up guidance in the 40MX/42MX datasheet (DS2316) to avoid latch-up during ramp sequencing.
The 208-PQFP has a 0.5mm pin pitch and 28x28 mm body. Use a standard PQFP-208 land pattern with solder paste on all pads; the exposed center area may carry a grounded thermal relief pad per package drawing. Route 5V I/O traces with adequate spacing from 3.3V core-domain signals, and keep configuration/JTAG pins with series termination near the header.
Do not mix speed grades without re-closing timing: the PQG208A 'A' grade and -1/-3 grades have different delay tables in the datasheet. Also confirm the temperature suffix (commercial vs industrial I vs military M) matches your program requirements, since design sign-off on one grade does not guarantee timing at another. Package is tray, not reel - plan for manual or tray-fed assembly.
