Typical Applications
A42MX09-2PLG84 is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control Systems, Mil/Aerospace Subsystems, High-Volume ASIC Prototyping, Embedded Bus Interface Logic, Test and Measurement Fixtures.
Legacy PLD Consolidation
The A42MX09-2PLG84 is purpose-built for merging multiple legacy PLDs and small CPLDs into a single chip. Its 5.0 V-tolerant 0.45 um architecture and dual 3.3 V/5 V supply operation let older 22V10-class PLD designs integrate without level shifters, while 14,000 system gates provide ample capacity for several devices at once. Because the antifuse fabric is one-time programmable and non-volatile, no configuration PROM or boot sequence is needed, preserving the deterministic power-up behavior of the original PLD design while reducing BOM count and board area.
Recommended
Industrial Control Systems
In factory automation and industrial controllers, the A42MX09-2PLG84 provides glue logic, sequencing, and interface control with deterministic antifuse timing. The dual 4.5-5.5 V and 3.0-3.6 V supply ranges allow direct connection to both legacy 5 V sensor buses and modern 3.3 V logic. Its 5.6 ns clock-to-out and 161-269 MHz grade limits support state machines and decode functions faster than typical CPLDs. Non-volatile one-time programming ensures the control logic is present at power-up without host processor intervention, an important reliability attribute in unattended industrial equipment.
Recommended
Mil/Aerospace Subsystems
Actel/Microsemi antifuse FPGAs have a long heritage in military and aerospace programs, and the A42MX09-2PLG84 continues that role in non-radiation-critical subsystems. The one-time-programmable configuration is immune to configuration-bit readout and power-up configuration upset, giving deterministic behavior that SRAM FPGAs cannot match without external mitigation. The metal-to-metal antifuse interconnect provides low on-resistance routing and resistance to latch-up. The PLCC-84 J-lead package suits high-reliability solder inspection and board-level rework practices common in defense production.
Recommended
High-Volume ASIC Prototyping
The MX family serves as a low-cost, single-chip ASIC alternative for high-volume products that previously used gate arrays. The A42MX09's antifuse fabric delivers deterministic timing comparable to mask-programmed logic, so a gate-array netlist can be mapped into the 42MX architecture using Libero IDE tools and evaluated before committing to mask costs. At 14,000 gates, the device covers small-to-medium ASIC front-end designs, and the -2 speed grade sustains internal clock rates up to 250 MHz, adequate for data-path and controller blocks in 5 V industrial product lines.
Recommended
Embedded Bus Interface Logic
The A42MX09-2PLG84 excels as address decoding, bus arbitration, and wait-state logic for legacy microprocessor systems. Its fast wide-decode circuitry and 100 MHz FIFO support (family capability) handle 5 V bus timing margins directly, while dual-port SRAM blocks (up to 2.5 kbits family-wide, 5 ns access) implement FIFOs and register files on-chip. Because configuration is non-volatile, bus logic is active from the first clock cycle, simplifying power-on reset design in systems where the processor boots immediately.
Recommended
Test and Measurement Fixtures
Production test fixtures and bed-of-nails boards benefit from the A42MX09's one-time-programmable, tamper-resistant configuration: test sequences cannot be altered in the field, protecting proprietary test IP. The 72 user I/O pins interface with 5 V legacy instrument lines and 3.3 V DUT domains, and 5.6 ns clock-to-out supports fast handshake timing. The low-cost PLCC-84 package suits fixture volumes where per-unit cost dominates, and DigiKey stock availability supports quick fixture rebuilds as of 2026-08-30.

Key Differentiators
- Non-volatile OTP antifuse configuration (vs SRAM-based FPGAs (e.g., Xilinx/Intel parts))
- Dual 3.3 V / 5 V operation (vs A42MX09-FPLG84 and modern FPGAs)
- Cost versus in-family density upgrade (vs A42MX24-3PLG84)
Design Notes
The A42MX09 is one-time programmable: once antifuse interconnects are burned, the device cannot be reprogrammed. Complete full functional simulation in Libero IDE (or Legacy Actel Designer) and verify I/O assignment against your PLCC-84 land pattern before programming. Budget for spare programmed devices; a design change requires new parts, unlike SRAM FPGAs. Order prototypes with margin of at least 20% over test quantity.
The dual-voltage architecture requires correct supply selection: connect 4.5-5.5 V for 5 V system I/O or 3.0-3.6 V for 3.3 V systems per the A42MX09 datasheet. Decouple each supply pin pair with 0.1 uF ceramic capacitors placed within 5 mm of the pin, plus bulk 10 uF per rail. Confirm current demand against your regulator, since antifuse fabric draws static current only during programming; runtime current is dominated by I/O switching.
The PLCC-84 J-lead package requires the standard JEDEC PLCC-84 land pattern; J-leads allow visual solder inspection and easier rework than QFP gull-wing leads. Keep 5 V switching I/O traces away from sensitive analog nets, and use a solid ground plane beneath the device. For programming via a programmer socket or in-system programming fixture, reserve access to dedicated programming pins as described in the A42MX09 programming documentation.
