A40MX04-PL68M

Overview

The A40MX04-PL68M is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features approximately 6,000 system gates and 547 logic elements. The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It offers 57 user-programmable I/O pins and is housed in a 68-pin PLCC package. The component operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports mixed-voltage core and I/O operation for compatibility with both 3.3V and 5.0V systems
• Provides deterministic timing through user-controllable clock routing and pin locking capabilities
• Enables high resource utilization with up to 100% pin locking and resource usage flexibility

Applications

• High-capacity single-chip ASIC replacement
• Mixed-signal interface bridging between different voltage domains
• Discrete logic consolidation in industrial control systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical characteristics and package variations. Ensure compliance with RoHS directives and check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement plans.

Selection Notes

Select this model when a moderate gate count FPGA with robust 5V tolerance is required. Compare against other MX series variants based on specific I/O pin counts and package size constraints. Confirm that the 68-pin PLCC form factor fits the target PCB layout requirements.

Part Context

This component belongs to the Actel/Microchip MX family of SRAM-based FPGAs. These devices are designed as drop-in replacements for complex programmable logic devices (CPLDs) and standard ASICs. The family emphasizes low power consumption and ease of integration for legacy system upgrades.

Replacement Considerations

Direct pin-compatible substitutes within the same MX family include the A40MX02 and A40MX08 variants, depending on whether lower or higher logic density is needed. Verify that the alternative part number maintains the same 68-pin PLCC package and voltage specifications.
