A40MX04-3PL44I

Overview

The A40MX04-3PL44I is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family. It provides approximately 6,000 system gates and 547 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with supply ranges of 3V to 3.6V or 4.75V to 5.25V for core and I/Os. It features up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The component utilizes a 44-pin Plastic Quad Flatpack (PQFP) package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V logic systems.
• Includes configurable dual-port SRAM blocks for efficient data buffering and FIFO applications.
• Features deterministic timing with user-controllable pin locking and resource utilization.

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage interface bridging between different logic families
• Industrial control systems requiring robust programmable logic

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the package type matches the required PCB footprint. Ensure compatibility with the programming toolchain for the MX FPGA family before procurement.

Selection Notes

Select this model when 6,000 system gates are required in a compact 44-pin package. Compare against other MX variants if higher gate counts or different package styles like PLCC or QFP are needed. Verify voltage requirements match the 3.3V or 5.0V operating modes specified in the electrical characteristics.

Part Context

This part belongs to the Microchip MX FPGA family, designed as a high-capacity alternative to complex ASICs. The series offers scalable gate counts ranging from 3,000 to 54,000 system gates. The A40MX04 variant specifically targets applications needing moderate logic density with embedded memory resources in a small form factor.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages such as A40MX04-1PLG68 or A40MX04-CQ100I. Cross-reference pinouts and thermal specifications when changing package types. Verify that the speed grade meets the target clock frequency requirements.
