A42MX09-2PLG84 概要
An FPGA (Field Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that the designer configures after manufacturing. FPGAs sit within the broader hierarchy of programmable logic devices, above CPLDs and PLDs in capacity, and the MX family is distinctive because it uses antifuse technology, which is one-time programmable, non-volatile, and inherently immune to configuration bitstream readout, making it a reliable single-chip ASIC alternative.
Key features include the efficient 5.0 V-tolerant 0.45 um architecture, dual voltage operation (3.3 V core logic compatibility alongside 5 V I/O), up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and 100 MHz FIFO capability. The antifuse fabric requires no external configuration PROM or boot process, simplifying power-up design and improving system reliability in high-volume applications.
Architecturally, the MX family combines Actel's multiplexer-based combinational logic modules with flip-flop-based sequential elements, connected through a metal-to-metal antifuse interconnect programmed at the factory or in-house programming station. This yields low on-resistance interconnects, deterministic timing, and resistance to radiation-induced configuration upset compared to SRAM-based FPGAs.
Typical applications include legacy PLD consolidation onto a single low-cost chip, industrial control, mil/aerospace subsystems, and high-volume embedded control where 5 V I/O compatibility and single-chip integration are required.
Design consideration: because the device is one-time programmable, verify the design fully in simulation with Libero IDE before programming; plan I/O assignment carefully since antifuse FPGAs cannot be reconfigured in-circuit.

主な用途
A42MX09-2PLG84 の用途: 6 件s: 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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
