A40MX04-PL84M

Overview

The A40MX04-PL84M is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 6,000 system gates and 547 logic elements within a 68-LCC (J-lead) package. The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable delays. The component operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports mixed-voltage core and I/O operations for compatibility with 5.0V or 3.3V systems.
• Provides deterministic, user-controllable timing for precise signal path management.
• Enables 100% resource utilization and 100% pin fixing for stable ASIC-like performance.

Applications

• Single-chip ASIC replacement in automotive applications
• Industrial control systems requiring deterministic timing
• Embedded logic integration in mixed-voltage environments

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade variant or specific packaging configuration, as standard datasheets may list generic PL84 packages. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this model when a high-density FPGA with fixed pinout requirements is needed for ASIC prototyping or production. The PL84 package suits surface-mount applications where space is limited but I/O count is moderate. Compare logic element counts and SRAM capacity against other MX family members like the A40MX02 or A40MX04 variants to ensure sufficient resources for the target design complexity.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between discrete logic and custom ASICs. The A40MX04 series specifically targets applications requiring high reliability and low power consumption. The PL84 designation indicates a plastic leaded chip carrier package with 84 pins, offering a balance between I/O density and board space efficiency for mid-range logic designs.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages such as A40MX04-PLG68 or A40MX04-VQG80, provided pin compatibility is verified. Cross-family replacements from Actel or Lattice require careful review of logic architecture and I/O voltage levels to ensure functional equivalence.
