Typical Applications
A42MX16-1VQG100I is suitable for 6 applications: Legacy PLD / Glue Logic Consolidation, Industrial Control Systems, Configuration-Secure Military/Aerospace Logic, High-Volume Consumer/ASIC Replacement, Test & Measurement Interface Logic, Networking and Communication Backplanes.
Legacy PLD / Glue Logic Consolidation
The A42MX16-1VQG100I is explicitly targeted by Microchip at integrating legacy PLDs into a single low-cost device. With 24,000 gates and 608 logic cells, it absorbs multiple TTL, 74xx, and CPLD glue-logic chips, cutting BOM count and board area. Its 5V-tolerant I/O on a 3.3V/5V supply connects directly to legacy bus levels without level shifters, and antifuse non-volatility removes boot-flash cost. In high-volume retrofit boards, per-unit savings come from eliminated configuration devices and simplified assembly.
Recommended
Industrial Control Systems
Industrial controllers benefit from the -40C to +85C industrial rating (I suffix) and deterministic antifuse timing. The A42MX16-1VQG100I implements sequencers, address decoders, and bus interfaces with no configuration-load delay at power-up - useful where deterministic startup matters. Its 119-198 MHz toggle capability covers common PLC and motor-control peripheral logic, while the 100-TQFP surface-mount package withstands vibration better than through-hole alternatives. Pair with industrial-grade transceivers for field-bus interfaces.
Recommended
Configuration-Secure Military/Aerospace Logic
Antifuse programming cannot be read back, making the A42MX16 family attractive for defense and aerospace subsystems where bitstream security matters. The same die is offered in M-grade screening (e.g., A42MX16-1VQG100M), enabling path-to-military qualification without redesign. One-time programming also eliminates configuration upset from SEU-like boot faults in harsh environments. Logic capacity of 24K gates suits mission sequencers, telemetry formatters, and interface bridges.
Recommended
High-Volume Consumer/ASIC Replacement
As a single-chip ASIC alternative on a mature 0.45 um CMOS process, the A42MX16-1VQG100I avoids ASIC NRE for volumes of thousands to millions of units. Microchip positions MX as a high-volume platform, and antifuse programming means every unit ships pre-configured with no firmware loading at board test. Unit cost is competitive at volume, and the 100-TQFP is standard reflow-compatible. Trade-off: no field updates - design must be frozen before production.
Recommended
Test & Measurement Interface Logic
The JTAG boundary-scan chain (TDI-to-TDO register per DS2136) supports board-level interconnect test, making the A42MX16-1VQG100I useful as test-access and interface logic in ATE fixtures and measurement backplanes. Its 83 I/O terminate address/data/control buses, while deterministic antifuse delays simplify timing closure for strobe generation. Dual 3.3V/5V rails interface directly with both legacy TTL instruments and 3.3V logic analyzers without translation.
Recommended
Networking and Communication Backplanes
With toggle rates to 198 MHz, the A42MX16-1VQG100I implements backplane address decoding, interrupt controllers, and simple protocol glue for telecom and networking cards. Its 5V-tolerant I/O suits legacy 5V backplane standards still common in industrial networking frames. Non-volatile antifuse configuration means cards enumerate instantly at power-up with no bitstream download, reducing boot time - valuable in redundant systems requiring fast failover.

Key Differentiators
- One-time-programmable non-volatile configuration (vs SRAM-based FPGAs (e.g., modern Microchip PolarFire))
- 5V-tolerant I/O on dual 3.3V/5V rails (vs A42MX16-1VQG100 commercial grade)
- Faster guaranteed timing option exists in same footprint (vs A42MX16-2VQG100I / A42MX16-3VQG100I)
Design Notes
Decouple every VCC pin of the A42MX16-1VQG100I with a 0.1 uF ceramic capacitor placed within 2-3 mm of the pin, plus one bulk 10 uF per supply rail. The MX family runs dual 3.3V/5V rails; ensure both rails are present before or simultaneously with configuration-free operation (antifuse devices are active immediately at power-up, so brownout during ramp can cause logic misoperation). Refer to Microsemi datasheet DS2136 power-supply guidelines for exact sequencing tolerance.
Antifuse FPGAs are one-time programmable. There is no rework path after programming, so complete full timing simulation and functional verification in Microchip Libero/Designer before committing production units. Do not rely on last-minute HDL changes; a re-spin requires new physical devices. Reserve the JTAG chain (TDI, TDO, TMS, TCK) with test-point access for programming and boundary-scan production test.
With 83 I/O on a 100-pin TQFP, plan ground return paths: use at least 4-6 of the available GND pins and pour a solid ground plane under the device. For 198 MHz-class internal toggles appearing at I/O, add 22-33 ohm series resistors on fast outputs driving off-board loads to control ringing and EMI. Keep 5V-tolerant input stubs short when interfacing legacy TTL buses to avoid reflections.
Compliance Information
Newark lists A42MX16-1VQG100I as RoHS Compliant: Yes and lead free (G suffix). REACH/halogen/conflict-minerals status not stated in verified data.
