A40MX04-1PL84I

Overview

The A40MX04-1PL84I 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 package. The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers 69 user-programmable I/O pins. Operating temperatures range from -40°C to +85°C for industrial applications.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V systems.
• Provides deterministic, user-controllable timing suitable for precise design methodologies.
• Enables up to 100% resource utilization and pin locking for efficient ASIC-like implementation.

Applications

• Automotive electronic control units
• Industrial automation controllers
• Mixed-signal interface circuits

Procurement Notes

Verify the specific suffix '1' indicates the correct speed grade and temperature range (-40°C to +85°C). Confirm the PLCC-84 package availability through authorized distributors. Check for recent Product Change Notifications regarding assembly sites or software updates before finalizing procurement orders.

Selection Notes

Select this model when 6,000 system gates and 69 I/Os are required in a PLCC-84 form factor. Ensure the design utilizes mixed-voltage capabilities if interfacing with legacy 5V components. Compare against the A40MX02 variant if lower gate counts suffice, or the A42MX series for higher capacity needs.

Part Context

This component belongs to the Actel MX family, now under Microchip Technology. It serves as a non-volatile FPGA solution replacing complex discrete logic. The part number structure identifies the gate count (04), package type (PL84), and performance grade (1).

Replacement Considerations

Direct replacements include other variants within the A40MX04 series such as A40MX04-1PLG84I or A40MX04-CQ100I, depending on package requirements. Verify pin compatibility and voltage levels when substituting with older Microsemi branded parts.
