Typical Applications
A42MX09-1VQG100M is suitable for 6 applications: Legacy PLD Consolidation, Defense and Aerospace Upgrades, 5V Industrial Control Systems, Obsolete ASIC Replacement, High-Volume Embedded Systems, Test and Measurement Fixtures.
Legacy PLD Consolidation
The A42MX09-1VQG100M integrates multiple legacy PLDs, PALs, and GALs into one 14K-gate, single-chip device, exactly the use case Microchip markets the MX family for. Its native 5.0V I/O architecture interfaces directly with legacy 5V microprocessor buses and peripherals without level translators, and the 83 user I/Os provide ample connectivity for consolidated decode, glue, and sequencing logic. Because programming is antifuse and non-volatile, the consolidated design configures instantly at power-up, preserving the behavior of the replaced discrete devices while cutting board area and BOM count in high-volume legacy systems.
Recommended
Defense and Aerospace Upgrades
The M temperature suffix provides extended/military screening, making this part well suited to defense platform upgrades where original ASICs or PLDs are obsolete. The antifuse interconnect is inherently immune to configuration memory upset, and non-volatile programming removes the need for radiation-vulnerable external configuration flash. With 336 logic cells at 148 MHz/247 MHz toggle rates, it implements address decode, bus interface, and control logic inmil-qualified systems. Designers should map the legacy design into the MX architecture using Libero and validate timing at the -1 speed grade before submitting flight or program hardware.
Recommended
5V Industrial Control Systems
Industrial controllers built around 5V microprocessors and buses benefit from the A42MX09-1VQG100M's direct 5.0V I/O, which eliminates level-shifting circuitry and its associated failure points. The 83 user I/Os handle parallel buses, encoder inputs, relay-driving decode logic, and interlock sequencing, while 336 cells provide sufficient capacity for state machines and counters. The one-time-programmable antifuse array ensures deterministic power-up behavior in noisy factory environments where SRAM FPGA configuration corruption is a concern. Dual 3.3V/5V operation also allows mixed-voltage subsystem integration on a single chip.
Recommended
Obsolete ASIC Replacement
As a single-chip ASIC alternative, the MX family revives end-of-life ASIC and gate-array functions without mask charges or minimum-order quantities. The A42MX09's 14K gates and 336 cells cover small-to-medium ASIC replacements such as bus arbiters, interface converters, and custom peripherals originally implemented at 0.5um-to-1um geometries running from 5V supplies. The 148 MHz/247 MHz toggle rates comfortably exceed the speeds of the legacy processes being replaced. Antifuse programming fixes the design permanently, replicating ASIC-like tamper resistance and configuration immutability in original-equipment platforms.
Recommended
High-Volume Embedded Systems
Microchip positions MX as a high-volume platform, and the 100-pin VQFP package supports standard surface-mount assembly for cost-sensitive production runs. The A42MX09-1VQG100M fits embedded products that need a fixed, verified logic function - for example, power sequencing controllers, backplane interface logic, or sensor aggregation - delivered at low unit cost in volume. Non-volatile antifuse configuration removes the BOM cost of a configuration flash device, and the 3.3V/5V dual-supply operation eases integration into mixed-architecture products with legacy 5V peripherals alongside newer 3.3V logic.
Recommended
Test and Measurement Fixtures
Production test fixtures and bench instruments frequently need deterministic glue logic between legacy 5V instrumentation buses and modern controllers. The A42MX09-1VQG100M provides 336 cells of configurable decode, timing, and handshaking logic with 5V-tolerant I/O matching legacy TTL levels directly. Because the antifuse configuration is write-once and non-volatile, fixture logic cannot be accidentally altered or corrupted between test runs - a common failure mode with SRAM CPLDs in production environments. The 100-pin TQFP socketing and rework is straightforward with standard gull-wing tooling.

- Lower cost at equal footprint (vs A42MX16-1VQG100M)
- Faster timing available without redesign (vs A42MX09-3VQG100)
Design Notes
MX antifuse FPGAs are one-time-programmable: a design error permanently consumes a device. Complete full gate-level simulation and static timing analysis in Actel Designer/Libero before programming, and prototype with the commercial A42MX09-1VQG100 rather than the screened M-grade part. Reserve spare logic cells and I/O pins in your floorplan for late ECOs, since no design iteration is possible on an already-programmed device.
The MX family operates from dual 3.3V/5V supplies; tie unused supply pins per the MX datasheet power connection tables and decouple each VCC domain with 0.1uF ceramics close to the package pins plus one bulk 10uF per rail. Because the 0.45um CMOS core is static, quiescent current is low, but simultaneous switching of 83 outputs at 5V can create ground bounce - use generous ground returns and enable output slew limits where available.
The 100-pin VQFP/TQFP has 0.5mm-pitch gull-wing leads requiring fine-pitch land patterns per IPC-7351 class guidance. Keep trace lengths under the device matched for parallel bus interfaces, and route 5V-tolerant I/O with series termination (22-33 ohm) when driving long or capacitive lines to control ringing. Verify MSL handling before reflow - bake if the moisture-barrier bag indicator shows exposure.
