Typical Applications
A42MX16-1PQG208 is suitable for 6 applications: Legacy PLD Consolidation, ASIC Prototyping, Industrial Control Systems, Aerospace and Defense, Communication Equipment, Test and Measurement Fixtures.
Legacy PLD Consolidation
The MX family is explicitly positioned by Microchip as a platform for integrating legacy PLDs into a single low-cost device. With 24,000 system gates, 608 logic cells, and 140 user I/O, the A42MX16-1PQG208 can absorb multiple 22V10-class PLDs and glue logic into one 3.3V/5V-tolerant package. Antifuse configuration means no external configuration PROM and instant power-up, simplifying board bring-up compared to SRAM FPGA designs.
Recommended
ASIC Prototyping
MX FPGAs offer a reliable single-chip ASIC alternative for prototyping and low-to-mid-volume production. The 0.45um antifuse process and deterministic routing suit gate-array-style flows, and Microchip provides conversion paths from FPGA prototypes to structured ASIC derivatives. The 140 I/O and 119MHz/198MHz internal performance cover many legacy ASIC interface requirements while the PQ208 footprint transitions to ceramic CQ208 for qualification builds.
Recommended
Industrial Control Systems
In industrial controllers and motor-drive interface cards, the A42MX16-1PQG208 provides 5V-tolerant I/O that directly connects to legacy sensors, relays, and PLC backplanes without level shifters. Speed grade -1 timing at 119MHz/198MHz is ample for state machines and bus interface logic. Industrial-temperature sibling A42MX16-1PQG208I is a drop-in for harsh-environment builds on the identical PCB.
Recommended
Aerospace and Defense
The MX family is fully tested over automotive and military temperature ranges, and the A42MX36 is available in CQ208/CQ256 ceramic packages screened to MIL-STD-883. Designers prototype on the plastic PQ208 and convert to ceramic for flight builds because PQ208 and CQ208 are pin-compatible. The antifuse configuration is immune to configuration upsets from radiation-induced readback and offers secure, non-volatile storage valued in defense programs.
Recommended
Communication Equipment
Line cards and backplane interface logic in telecom and datacom equipment benefit from the A42MX16-1PQG208's 140 user I/O and mixed 3.3V/5V operation, bridging 5V legacy line interfaces to 3.3V logic domains. Deterministic antifuse routing supports predictable timing for framing, multiplexing, and protocol glue logic, while non-volatile configuration ensures the link is immediately operational at power-up with no boot delay.
Recommended
Test and Measurement Fixtures
Production test fixtures and JTAG-based board test setups use the A42MX16-1PQG208 to implement scan controllers, pattern generators, and bus capture logic. Family IEEE 1149.1 boundary-scan support enables board-level interconnect test integration, and the -1 speed grade delivers adequate 119MHz-class performance for fixture-side logic. Its 208-pin PQFP provides abundant I/O for contacting multi-connector boards under test.

Key Differentiators
- Non-volatile antifuse configuration - no boot PROM (vs SRAM FPGAs (e.g., Xilinx/Altera equivalents))
- Pin-compatible density scaling in PQ208 (vs A42MX24-1PQG208I / A42MX36-1PQG208)
- Dual 3.3V/5V I/O operation (vs Modern low-voltage FPGAs)
Design Notes
The MX architecture supports 3.3V and 5V operation. Decouple VDD pins with 0.1uF ceramic capacitors at each supply pin plus bulk 10uF near the device. Because antifuse devices draw no configuration current at power-up, inrush is minimal - but verify I/O bank currents when driving 5V legacy loads at 140 I/O to stay within package power limits.
The PQFP-208 has 0.5mm-pitch leads; use a 0.65mm-center footprint per the DS2316 mechanical drawing and verify with your assembler. Since PQ208 is pin-compatible with CQ208 ceramic, design the footprint once to allow prototype-to-production and high-reliability conversion without PCB spin.
Antifuse programming is one-time: a design change requires a new physical device, so reserve engineering spare gates and route spare I/O to test points before committing. Also note IEEE 1149.1 JTAG detail in DS2316 is explicitly described for 42MX24/42MX36 - validate the A42MX16 scan chain in your test plan rather than assuming identical compliance.
Compliance Information
G suffix denotes lead-free/RoHS-compliant version (distributor listing: LEAD FREE). Automotive-temperature MX variants exist per Microchip automotive datasheet DS0025; AEC-Q100 qualification status for this exact MPN not confirmed in provided data.
