Typical Applications
A42MX24-3TQG176 is suitable for 6 applications: Legacy PLD Consolidation, ASIC Prototyping and Bridge, Industrial Control and Automation, Test and Measurement Equipment, Communication and Interface Bridging, Aerospace and Defense Legacy Sustainment.
Legacy PLD Consolidation
The A42MX24-3TQG176 is purpose-built by Microchip for integrating multiple legacy PLDs and GAL/PAL devices into a single low-cost MX FPGA. With 36,000 gates and 150 I/Os, it absorbs several 22V10-class devices plus glue logic while its 5.0V-tolerant architecture directly connects to the 5V buses these legacy designs assume. Placed on the same board with no level-shifters, it cuts BOM count and board area. The trade-off is one-time HDL conversion effort from schematic-era designs into Libero-compatible source.
Recommended
ASIC Prototyping and Bridge
As a single-chip ASIC alternative, the A42MX24-3TQG176 lets teams validate RTL before ASIC commitment. The 912-cell fabric with C-, S-, and D-modules supports moderate-throughput datapaths, while the D-module wide-decode logic accelerates address decoding similar to CPLD structures. At a -3 speed grade it handles control and interface logic in the tens-of-MHz range. Teams prototype in this package, then port unchanged HDL to volume production, reducing mask-set risk on 36K-gate-class ASICs.
Recommended
Industrial Control and Automation
In factory controllers and machine interfaces, the A42MX24-3TQG176 implements state machines, encoder interfaces, and parallel bus bridges. Its 0C to +70C commercial range suits enclosed cabinet environments, and the 5V I/O compatibility simplifies retrofit into older 5V sensor and actuator buses. The 150 available I/Os support wide parallel fieldbus signals without external fan-out logic. For unconditioned or outdoor installations, specify the -I industrial variant instead of this commercial-grade part.
Recommended
Test and Measurement Equipment
Bench instruments and ATE modules use the A42MX24-3TQG176 for pattern generation, trigger logic, and bus arbitration. The -3 speed grade supports system clocking in the tens of MHz, adequate for many control-plane functions, while D-modules implement fast wide-input comparison logic for trigger qualification. Dual 3.3V/5V operation matches legacy backplane voltage standards common in rack systems. Deterministic MX fabric timing (no embedded RAM latency surprises) simplifies timing closure for fixed-latency measurement paths.
Recommended
Communication and Interface Bridging
The A42MX24-3TQG176 bridges parallel legacy buses (ISA-style, VME glue) to newer controllers. With 150 I/Os it terminates wide address/data buses directly, and the 5V-tolerant fabric removes level-shifting stages that would otherwise add propagation delay and parts count. Microchip's MX family was explicitly designed for such high-volume interface integration. For designs exceeding 36K gates or 150 I/Os, migrate to A42MX36 in the 208-pin package using the same Libero project flow.
Recommended
Aerospace and Defense Legacy Sustainment
Defense depots sustaining 1990s-era avionics and ground systems rely on MX-family FPGAs because Microchip (formerly Actel/Microsemi) continues the line with military-screened options (M suffix). The A42MX24 die in 176-TQFP replaces obsolete custom logic without board redesign, preserving qualified form factor. The 5V I/O matches older mil-spec digital signaling. Long-term availability commitments and identical-die variant families (standard, I, M) make obsolescence management tractable for programs with decades-long service lives.

Key Differentiators
- Fastest commercial speed grade in 176-TQFP (vs A42MX24-TQG176)
- Industrial and military screened variants on identical die (vs A42MX24-1TQG176I)
- Larger fabric than same-package A42MX16 (vs A42MX16-3TQG176)
Design Notes
The A42MX24 operates from dual 3.3V and 5V rails. Decouple each supply with at least 0.1 uF ceramic per power pin plus bulk 10 uF capacitance. Observe datasheet DS2316 power-up behavior guidance for A42MX24 - supply sequencing during power-up affects configuration reliability, so ensure 5V and 3.3V rails rise monotonically and within datasheet slew-rate limits.
The 176-TQFP (24 mm x 24 mm) with 1.60 mm height has limited thermal dissipation capability. MX-family static power is modest at 5V, but I/O switching power at 150 pins can add up in wide-bus designs. Provide at minimum a solid ground plane and thermal vias near the package for commercial 0C to +70C ambient operation; use airflow in enclosed instrument chassis.
Do not confuse commercial (-3TQG176) and industrial (-3TQG176I) grades - this commercial part is limited to 0C to +70C and will not meet industrial qualification. Additionally, MX-family designs must be implemented in Libero/Designer tooling with correct speed-grade selection; programming a bitstream compiled for a different speed grade is not supported. Verify D-module decode usage in timing simulation, as wide-decode paths have distinct timing from C/S-module paths.
