Typical Applications
A42MX36-2PQG208 is suitable for 6 applications: Legacy 5V System Integration, Industrial Control and Automation, High-Reliability Aerospace and Defense, ASIC Prototyping and Bridge Logic, Test and Measurement Equipment, Medical Device Control Electronics.
Legacy 5V System Integration
The A42MX36's 5V-tolerant I/O rail (4.5V-5.5V) directly interfaces with TTL, 5V CMOS microprocessors, and legacy backplanes without level translation, which is the primary reason designers migrate old multi-chip PLD, PAL, and glue-logic subsystems onto this device. Its 54,000 gates and 1184 CLBs absorb dozens of discrete 22V10/16V8 devices into a single non-volatile antifuse chip. Because the configuration is hard-wired at power-up with no boot delay or PROM read time, legacy timing behavior is preserved. Place 100nF decoupling per power pin group and verify 5V bus hold requirements during conversion.
Recommended
Industrial Control and Automation
In factory controllers and motor-control interface boards, the A42MX36-2PQG208 provides deterministic antifuse routing for sequencer, encoder-interfacing, and interlock logic where jitter and boot latency matter. The industrial -40C to +85C rating covers cabinet-mounted electronics, and the 2560-bit dual-port SRAM builds ping-pong FIFOs between a 16-bit MCU and peripheral control logic. The single-chip non-volatile design removes configuration storage reliability concerns in electrically noisy environments. Use the -2 speed grade when state-machine clocks approach the ~91 MHz fabric limit documented in Microchip parametric data.
Recommended
High-Reliability Aerospace and Defense
Antifuse fabric is inherently resistant to configuration upset because programmed connections are physical, not stored in vulnerable SRAM cells, making the 42MX a long-standing choice for satellite and avionics logic. The pin-compatible CQ208 ceramic package is screened to MIL-STD-883 levels, and Microchip tests all MX devices over automotive and military temperature ranges, so a board prototyped with PQ208 plastic converts directly to ceramic for flight builds. The 54K-gate capacity suits telemetry framing, bus interface, and redundancy-management logic. Design-in the A-suffix or FP order codes for qualifying programs.
Recommended
ASIC Prototyping and Bridge Logic
MX FPGAs were marketed by Microsemi as a reliable single-chip ASIC alternative, and the A42MX36 remains useful for low-volume bridge logic where an ASIC cannot be justified. Deterministic antifuse delays mean post-layout timing simulations closely match silicon, simplifying sign-off for interface bridges between processors and custom peripherals. The 176 user I/Os handle wide parallel buses, and the 5V I/O domain bridges older ASICs to newer 3.3V logic. Budget for one-time programming: iterate in simulation with Libero Designer, then commit, since antifuse devices are not reprogrammable.
Recommended
Test and Measurement Equipment
Bench instruments and automatic test equipment benefit from the A42MX36's fast, deterministic interconnect for timing generators, comparators, and pattern capture logic. The dual-port SRAM blocks implement capture FIFOs and stimulus buffers (32x8 or 64x4 per block, cascadable per DS2316), while 176 user I/Os address high-pin-count device-under-test sockets. The non-volatile antifuse configuration means instruments power up instantly into a known-good configuration with no loader, improving uptime in production test racks. Pair with precision amplifiers and reference circuits for complete measurement front ends.
Recommended
Medical Device Control Electronics
Benchtop diagnostic and monitoring equipment uses the A42MX36-2PQG208 for deterministic interface and safety-interlock logic. The instant-on non-volatile antifuse configuration guarantees that safety interlocks are active before software loads, an advantage over SRAM FPGAs that require configuration time at each power-up. The -40C to +85C industrial range covers clinical environments, and ROHS3 compliance supports modern medical manufacturing requirements. Its 5V-tolerant I/O connects directly to legacy sensor boards common in long-lifecycle medical platforms, where multi-decade service life favors mature, stable silicon.

Key Differentiators
- Fastest fabric in the PQ208 family (vs A42MX36-1PQG208)
- Non-volatile antifuse configuration (vs Xilinx/Intel SRAM FPGAs)
- Pin-compatible path to MIL-STD-883 ceramic (vs A42MX36-2PQG208I)
Design Notes
The A42MX36 requires two supply domains: 3V-3.6V core and 4.5V-5.5V I/O. Sequence or rail-load design must tolerate the 5V domain powering first; refer to the 40MX/42MX datasheet power-up characteristics. Provide 100nF ceramic decoupling per power-pin group plus bulk 10uF per rail. Total power depends on toggle rate - use the Designer software power estimator, since antifuse interconnect capacitance is fixed and predictable once routed.
Antifuse FPGAs are one-time programmable: a design error after programming cannot be corrected on the same device. Complete post-layout timing simulation with the Designer tool's SDF back-annotation before programming, and keep at least one spare programmed and unprogrammed device per board revision. Also, per Microchip product data, the manufacturer lead time is 12 weeks - do not wait for stock-outs to reorder.
The 208-pin PQFP has a 0.5mm pin pitch and 28x28mm body; use a solder-mask-defined land pattern per the Microchip package drawing and inspect with X-ray or AOI after reflow. Gull-wing leads are flexible enough to absorb CTE mismatch on standard FR-4, but for the ceramic CQ208 conversion, verify board CTE matching for qualifying environments since ceramic bodies impose higher stress on solder joints.
Compliance Information
