A40MX04-PL84I

Overview

The A40MX04-PL84I is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 6,000 system gates and 547 logic elements within a PLCC-84 package. The device operates on dual voltage supplies: 3V to 3.6V and 4.75V to 5.25V. It supports industrial temperature ranges from -40°C to +85°C and includes IEEE 1149.1 JTAG boundary scan testing capabilities.

Feature Summary

• Provides deterministic timing with user-controllable delays for reliable system integration.
• Supports up to 100% resource utilization and 100% pin fixing for direct ASIC replacement.
• Enables unique in-system diagnostic capability through Silicon Explorer II technology.

Applications

• Automotive electronic control units requiring ASIC alternatives
• Industrial control systems needing deterministic timing
• Safety-critical embedded logic designs

Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature range of -40°C to +85°C against the official datasheet. Confirm the PLCC-84 package dimensions match your PCB footprint requirements. Check for recent Product Change Notifications regarding assembly sites or material composition updates before finalizing orders.

Selection Notes

Select this model when 6,000 system gates are sufficient for the design complexity. Ensure the board layout accommodates the PLCC-84 surface mount package. Compare against the A40MX04-VQG80 if a smaller VQFP-80 package is preferred, noting the I/O count difference. Verify power supply stability within the specified 3V and 5V rails.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between discrete logic and complex SoCs. The A40MX04 variant specifically targets mid-range logic density needs. It is part of a broader portfolio that includes higher-density parts like the A42MX series, offering scalable solutions for automotive and industrial markets.

Replacement Considerations

Publicly confirmed substitutes include other variants within the A40MX04 family such as A40MX04-PLG68I or A40MX04-CQ100I, provided the package and pinout compatibility are verified. No direct cross-manufacturer equivalents are documented in public sources.
