A40MX04-PL84A

Overview

The A40MX04-PL84A 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-pin PLCC package. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V and 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable constraints.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, compatible with 5.0V or 3.3V supplies.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin fixing capabilities.
• Includes unique in-system diagnostic capability via Silicon Explorer II for verification.

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems needing deterministic timing
• Mixed-voltage interface designs

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature range. Confirm RoHS compliance status as some variants may differ. Check for recent Product Change Notifications regarding assembly sites or software updates before ordering.

Selection Notes

Select this model for designs requiring 6,000 system gates with a 68-pin PLCC footprint. Ensure voltage requirements align with the specified 3V and 5V operating ranges. Consider the VQG80 variant if a QFP package is preferred for the same logical capacity.

Part Context

This component belongs to the A40MX04 series within the broader MX FPGA family. It shares architectural similarities with other members like the A40MX02 and A42MX24 but differs in gate count and package options. The PL84A designation specifically indicates the 68-pin plastic leaded chip carrier form factor.

Replacement Considerations

The A40MX04-VQG80 serves as a functional substitute offering identical logical resources in a VQFP-80 package. Verify pin compatibility and thermal characteristics when transitioning between PLCC and QFP footprints.
