A40MX04-2PQ100

Overview

The A40MX04-2PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip Actel MX family, designed as a high-capacity single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 2000 equivalent system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and includes up to 69 user-programmable I/O pins. The component is housed in a 100-pin Plastic Quad Flat Package (PQFP) and is rated for industrial temperature ranges.

Feature Summary

• High-density logic architecture providing an alternative to discrete ASIC solutions
• Integrated dual-port SRAM for fast data buffering and FIFO applications
• Wide-decode circuitry supporting complex address decoding tasks

Applications

• Industrial control systems requiring reliable programmable logic
• Automotive electronics operating in harsh environments
• Military and aerospace applications demanding radiation tolerance

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the PQFP-100 configuration. Check for RoHS compliance status relevant to your region's regulations before finalizing procurement orders.

Selection Notes

Select this model when a moderate gate count with 5V operation is required. Compare against the A40MX02 series for lower density needs or the A42MX series for enhanced radiation hardness. Confirm that the 48.24 MHz performance meets the timing requirements of the target design.

Part Context

This part belongs to the Microsemi/Actel MX FPGA family, known for non-volatile flash-based technology. The A40MX04 variant specifically targets applications needing higher logic capacity than the A40MX02 while maintaining pin compatibility within the same package families.

Replacement Considerations

Direct substitutes include other variants within the A40MX04 family such as A40MX04-CQ100I or A40MX04-2PL100A, provided the package and temperature specifications match the original design requirements.
