A40MX04-3PL68I

Overview

The A40MX04-3PL68I is a field-programmable gate array from the Microchip MX family, housed in a 68-pin PLCC package. It provides 547 logic elements and approximately 6,000 system gates. The device supports mixed-voltage operation with supply ranges of 4.5 V to 5.5 V for 5V I/Os and 3.0 V to 3.6 V for 3.3V I/Os. It features 57 user-programmable I/O pins and operates within a commercial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5V components on the same board.
• Offers deterministic timing through user-controllable delay chains and pin locking capabilities.
• Includes configurable dual-port SRAM blocks for efficient data buffering and storage applications.

Applications

• High-capacity single-chip ASIC replacement
• Mixed-signal interface bridging between different voltage domains
• Complex state machine implementation

Procurement Notes

Verify the specific speed grade suffix '3' against project timing requirements before ordering. Confirm that the PLCC-68 package footprint matches the PCB design. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly to prevent damage.

Selection Notes

Select this model when 6,000 system gates and 57 I/Os are sufficient for the design. Consider the -3 speed grade if higher performance than the base variant is needed but lower power consumption than faster grades is preferred. Ensure the 68-pin PLCC package fits the available board space.

Part Context

This component belongs to the A40MX04 series within the broader MX FPGA portfolio. It shares architectural similarities with other variants like the A40MX02 and A40MX08, differing primarily in logic density and I/O count while maintaining the same core configuration technology.

Replacement Considerations

Direct substitutes include other speed grades within the A40MX04-PL68 family, such as the A40MX04-1PL68I or A40MX04-2PL68I, provided their timing specifications meet the design constraints. Pin-compatible alternatives may exist within the same package type but require verification of logic resources.
