A40MX04-PLG84I

Overview

The A40MX04-PLG84I 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 69 I/O configuration. The device operates on a 3.3V or 5V supply voltage and supports mixed-voltage I/O operation compliant with PCI standards. Packaged in an 84-pin PLCC (J-leads) surface-mount format, it functions within a commercial temperature range of 0°C to 70°C. Key architectural attributes include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and deterministic user-controllable timing.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, enabling compatibility with 5.0V and 3.3V systems while maintaining PCI-compliant I/O levels.
• Provides deterministic, user-controllable timing characteristics suitable for applications requiring precise signal synchronization and predictable performance.
• Integrates configurable dual-port SRAM to facilitate efficient data buffering and processing within the programmable logic fabric.

Applications

• Single-chip ASIC replacement in automotive electronic control units
• Industrial automation controllers requiring deterministic timing
• Communication interface adapters supporting mixed-voltage protocols

Procurement Notes

Verify the specific suffix 'PLG84I' against the official Microchip datasheet to confirm package type and industrial temperature rating. Ensure compliance with RoHS directives and check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement specifications.

Selection Notes

Select this component when a low-gate-count FPGA with mixed-voltage I/O capability is required for prototyping or low-volume production. Compare pin counts and logic resources against the A40MX02 and A40MX04 variants to ensure optimal resource utilization. Verify that the PLCC-84 package fits the target PCB footprint and thermal requirements.

Part Context

This part belongs to the A40MX04 series within the broader MX FPGA family, which ranges from 3,000 to 54,000 system gates. It shares architectural similarities with other members like the A40MX02 and A42MX24 but offers a specific balance of logic density and I/O availability. The MX family is positioned as a cost-effective solution for replacing complex discrete logic or simple ASICs.

Replacement Considerations

Direct substitutes may include other devices within the A40MX04 series with different packages, such as the A40MX04-PLG44I or A40MX04-CQ100I, provided pin compatibility and I/O count requirements are met. Cross-family replacements require careful verification of logic resources and timing constraints.
