A42MX36-1PQG208 Descripción general
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing, offering a single-chip ASIC alternative. The MX family sits in the broader hierarchy of programmable logic devices (PLDs), bridging legacy CPLD/PLD integration and full ASIC development, and is a proven high-volume platform for consolidating legacy designs.
Key features include MultiPlex I/O supporting mixed-voltage systems, programmable PCI compliance with the PCI Local Bus Specification version 2.1 at both 5.0V and 3.3V, a low-power mode, and embedded dual-port SRAM modules optimized for FIFO, LIFO, and scratchpad datapath functions. The A42MX36 also contains wide-decode modules for high-fan-in address decoding, and the PQ208 package is pin-compatible with the CQ208 ceramic package used in MIL-STD-883 screened versions.
The device uses Actel's antifuse-style MX architecture (0.45um class CMOS process), delivering non-volatile, secure, single-chip configuration without external boot flash - a key reliability advantage for industrial and defense designs. Logic density is deployed through the Designer software and ACTgen Macro Builder for memory macro generation.
Typical applications include legacy PLD consolidation, industrial control, glue-logic integration, PCI interface bridging, and mil/aero systems requiring the ceramic-package variant. The 5.0V-tolerant I/O makes it especially suitable for interfacing with legacy 5V buses.
Design consideration: plan I/O banking carefully for mixed 3.3V/5.0V systems and verify timing at the -1 speed grade; use adequate decoupling on the multiple VCC/VCCA pins per the 40MX/42MX datasheet (DS2136) power guidelines.

Aplicaciones típicas
A42MX36-1PQG208 es adecuado para 6 aplicacións: Legacy PLD / Glue Logic Consolidation, PCI Interface Bridging, Industrial Control Systems, Mil/Aerospace Systems, FIFO / Data Path Buffering, Test and Measurement Instrumentation.
Legacy PLD / Glue Logic Consolidation
The A42MX36-1PQG208's 54,000 gates and 1184 CLBs allow designers to consolidate multiple legacy PLDs, PALs, and discrete glue logic into a single non-volatile chip. The MultiPlex I/O with 5.0V/3.3V tolerance directly interfaces with older 5V bus systems without level shifting, and the single-chip configuration removes boot PROMs. Wide-decode modules handle high-fan-in address decoding efficiently, making migration of decades-old board designs straightforward.
Recomendado
PCI Interface Bridging
Per the 40MX/42MX datasheet, the A42MX36 is fully compliant with the PCI Local Bus Specification version 2.1, supporting programmable PCI at 5.0V and 3.3V signaling. The 176 MultiPlex I/O pins supply enough capacity for a full 32-bit PCI master/target implementation plus application logic, while the -1 speed grade meets 33 MHz PCI timing. Non-volatile configuration ensures the bridge is active immediately at power-up, simplifying system bring-up.
Recomendado
Industrial Control Systems
In industrial automation, the A42MX36-1PQG208 provides deterministic programmable logic with 5V-tolerant I/O for sensors, actuators, and legacy PLC backplanes. Its non-volatile antifuse-class configuration survives power cycling without reconfiguration hardware, and the low-power mode reduces consumption in always-on installations. Dual-port SRAM blocks implement ping-pong buffers between control processors and field I/O, and the 208-PQFP industrial variants (I suffix) cover extended temperature deployments.
Recomendado
Mil/Aerospace Systems
The MX family's ceramic packaging options make the A42MX36 attractive for defense and aerospace. Per the FPGAkey family reference, the CQ208 and PQ208 devices are pin-compatible, enabling prototyping in plastic and production conversion to MIL-STD-883 screened ceramic packages without PCB changes. The non-volatile single-chip configuration offers inherent resistance to configuration upsets and readback, and the M-suffix variants (A42MX36-1PQG208M) address military screening requirements.
Recomendado
FIFO / Data Path Buffering
The A42MX36's embedded dual-port SRAM modules are optimized for high-speed datapath functions such as FIFOs, LIFOs, and scratchpad memory. Using the ACTgen Macro Builder in Microsemi Designer software, engineers instantiate FIFO queues of configurable width and depth without consuming general-purpose logic modules. This suits instrumentation, imaging, and communications boards that need independent read/write clock domains between acquisition front ends and processing elements.
Recomendado
Test and Measurement Instrumentation
The A42MX36-1PQG208 implements timing generators, trigger logic, and protocol decoders in test equipment, where the 176 user I/O connect to front-panel interfaces and measurement front ends. Non-volatile configuration means the instrument is functional the instant power is applied, and the 5.0V/3.3V MultiPlex I/O supports both legacy and modern probe interface standards. The -1 speed grade comfortably serves state-machine and decode paths in the tens of MHz range.

Notas de diseño
The A42MX36 uses separate VCC and VCCA supply pins in the 208-PQFP. Follow the 40MX/42MX datasheet (DS2136) power sequencing guidance: apply VCCA and VCC per the recommended order and decouple each supply pin with 0.1uF ceramics placed within 2 mm of the pin, plus bulk 10uF per rail. Mixed 3.3V/5.0V I/O banking requires each I/O bank's supply to match its signaling standard - never drive a 3.3V-configured bank from 5V logic.
The 208-pin PQFP has 0.5 mm pitch leads requiring fine-pitch soldering: use solder paste printing verified for 0.5 mm apertures and inspect with X-ray or AOI for bridging on the perimeter rows. The plastic PQ208 footprint is identical to the CQ208 ceramic package, so design the PCB once and switch to ceramic for mil/aero builds without re-layout, per the FPGAkey family reference.
The -1 speed grade is the slowest MX option - do timing closure in Microsemi Designer software before committing to PCB fab, especially for PCI v2.1 designs where 33 MHz setup/hold must be met. Do not assume SRAM-based Xilinx cross-references (XC5206, XC3195A) are drop-in: they need external configuration devices and different pin assignments. Also confirm lead finish requirements (G = lead-free vs non-G) for your compliance program.
Información de cumplimiento
G suffix in PQG208 denotes lead-free finish per Microchip/Microsemi naming. Lisleapex listing confirms LEAD FREE. ECCN 3A991.d.2 per legacy Microsemi records.
