A40MX04-FPLG84

Overview

The A40MX04-FPLG84 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 operates on supply voltages of 3V to 3.6V or 4.75V to 5.25V. It provides 57 I/O pins and supports surface-mount installation. The component functions without embedded memory and includes IEEE 1149.1 JTAG boundary scan capabilities for verification.

Feature Summary

• Acts as a single-chip ASIC alternative with deterministic timing and user-controllable delays.
• Supports synthesis-friendly architecture allowing up to 100% resource utilization and pin fixing.
• Enables unique in-system diagnostic capability through Silicon Explorer II integration.

Applications

• Automotive applications requiring low power consumption and high reliability.
• Industrial control systems needing deterministic timing and easy integration.
• ASIC design methodology prototyping with full pin fixing requirements.

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for recent Product Change Notifications regarding assembly sites or software updates. Ensure the supplier provides valid traceability documents matching the manufacturer's specifications.

Selection Notes

Select this model when 6,000 system gates and 57 I/Os are required in a PLCC-style footprint. Compare against A40MX02 variants if lower gate counts suffice. Verify voltage domain compatibility with 3.3V or 5V systems. Consider the absence of embedded RAM when designing state machines or data buffers.

Part Context

This part belongs to the A40MX series, which offers non-volatile SRAM-based FPGA technology. It sits between the smaller A40MX02 and larger A42MX devices in terms of capacity. The MX family is distinguished by its radiation tolerance options and automotive-grade availability within the broader Microchip portfolio.

Replacement Considerations
