A40MX04-3PLG84I

Overview

The A40MX04-3PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 6,000 system gates and 547 Logic Elements within a PLCC-84 surface-mount package. The device supports mixed-voltage operation with a supply range of 4.5 V to 5.5 V and operates within an industrial temperature range of -40°C to +85°C. It provides 69 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O configurations with PCI-compliant interfaces.
• Enables up to 100% resource utilization and 100% pin locking for deterministic timing and design stability.
• Includes unique in-system diagnostic capability via Silicon Explorer II for verification and testing.

Applications

• Automotive electronic control units requiring single-chip ASIC replacement
• Industrial automation controllers needing deterministic timing
• Mixed-signal interface circuits utilizing PCI-compliant I/O standards

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any recent Product Change Notifications regarding packaging or assembly site updates to ensure supply chain continuity and material consistency.

Selection Notes

Select this component when 6,000 system gates and 69 I/Os are required in a PLCC-84 footprint. Ensure the design utilizes mixed-voltage capabilities if interfacing with both 3.3V and 5V logic levels. Consider the PLCC-84 package constraints for PCB layout compared to QFP or BGA alternatives within the same gate count family.

Part Context

This part belongs to the A40MX04 series, which offers 6,000 system gates. Other variants in this series include the A40MX04-VQG80 (VQFP-80 package) and A40MX04-PLG44I (PLCC-44 package). The A40MX04 series serves as a bridge between complex CPLDs and larger FPGAs, offering SRAM-based reprogrammability with ASIC-like performance characteristics.

Replacement Considerations

Direct pin-compatible replacements within the same package require checking the suffix codes for temperature and speed grades. Verify that substitute parts maintain the 6,000 gate capacity and 69 I/O count. Cross-reference with other A40MX04 variants like the VQG80 only if the package type change is acceptable in the design.
