Typical Applications
A42MX09-2PQG100I is suitable for 6 applications: Glue Logic Consolidation, Industrial Control Systems, Legacy PLD Migration, Embedded System Interfacing, Power Supply Sequencing and Supervisory Logic, Test and Measurement Fixtures.
Glue Logic Consolidation
The A42MX09-2PQG100I consolidates discrete PALs, GALs, and TTL glue logic into one 14K-gate, 336-cell antifuse device, reducing board area and BOM count. Its 5V-tolerant, 3.3V/5V dual-supply I/O directly interfaces legacy TTL-level peripherals without level translators, and 83 user I/Os cover broad fan-out needs. Because configuration is one-time-programmable and non-volatile, the design cannot be corrupted in the field, an advantage over SRAM FPGAs in high-volume glue-logic replacement where reliability and unit cost dominate.
Recommended
Industrial Control Systems
In industrial controllers and motor-drive interface boards, the -40C to +85C industrial temperature grade and SEU-immune antifuse configuration give dependable operation in electrically noisy factory environments. The 161 MHz system performance and 269 MHz decode speed handle state machines, encoders, and PWM handshake logic, while 5V-tolerant I/O connects directly to legacy PLC signal levels. Its non-volatile programming means no configuration loader or external flash is needed, cutting qualification effort on long-lifetime industrial products.
Recommended
Legacy PLD Migration
The MX family is explicitly positioned by Microchip as a platform for integrating legacy PLDs into a single low-cost device. Designs based on discontinued Actel, Cypress, or AMD MACH parts can be re-fit into the 42MX architecture in Libero SoC, using the same 100-pin PQFP footprint across family members. The A42MX09-2PQG100I's 3.3V/5V I/O and industrial range preserve the original system's electrical interface, so boards can be refreshed without re-qualifying surrounding 5V circuitry.
Recommended
Embedded System Interfacing
Embedded CPU boards use the A42MX09-2PQG100I for bus bridging, memory decode, and interrupt aggregation at up to 161 MHz system speed. Its 0.45um antifuse process yields a fixed, deterministic timing profile that simplifies interface validation, and dual 3.3V/5V supply operation lets one device serve both legacy 5V microprocessor buses and modern 3.3V peripherals. One-time programmability prevents configuration-tampering concerns in shipped products, and the 83 I/Os provide dense parallel interface expansion.
Recommended
Power Supply Sequencing and Supervisory Logic
The device implements power-good gating, brownout response, and multi-rail sequencing state machines for systems with several supply domains. With 3.3V/5V dual-supply architecture it monitors and drives both voltage classes directly, and industrial temperature rating guarantees supervisory accuracy across -40C to +85C. Because the antifuse configuration is write-once, the sequencing logic is immutable against bit-flips, a reliability property that supervisor-only ICs and SRAM FPGAs cannot both provide in a single programmable device.
Recommended
Test and Measurement Fixtures
Production test fixtures and ATE adapters benefit from the one-time-programmable, tamper-resistant MX09 fabric: the test vector logic is fixed at programming time and cannot be altered by operators. 5V-tolerant I/O probes legacy TTL DUTs without protection circuits, 83 I/Os support wide parallel test channels, and the 100-pin PQFP is easy to socket on fixture boards. Industrial-grade temperature tolerance also suits uncontrolled factory-floor environments where commercial parts would derate.

Key Differentiators
- Industrial temperature grade (vs A42MX09-2PQG100)
- Faster speed grade (vs A42MX09-PQG100I)
- Lower cost at same footprint (vs A42MX16-PQ100)
Design Notes
The MX09 supports both 3.3V and 5V core/IO operation per DS2316. For 5V-tolerant interfacing, hold the VCCI domain at 5V and observe the datasheet Iih/Iil limits. Apply the programming voltage VPP only during programming per the Libero programming procedure - never during normal operation. Add 0.1uF ceramic decoupling per power pin plus bulk 10uF near the device.
MX antifuse devices are one-time programmable: there is no in-system rework. Complete full functional simulation, static timing analysis, and design signoff in Libero SoC before committing the bitstream. Do not swap speed grades (e.g., A42MX09-PQG100I for -2) without re-running timing, as -1 timing derates performance below 161 MHz-class system speed.
The 100-pin PQFP (BQFP) has a 0.65mm lead pitch; use a solder-mask-defined footprint per IPC-7351 conventions and verify the exposed lead-frame dimensions against the DS2316 package drawing. Keep fast I/O traces length-matched where they feed parallel buses, and place the device to keep the programming header accessible for manufacturing programming stations.
