A40MX04-3PLG68I

Overview

The A40MX04-3PLG68I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 547 Logic Elements and approximately 6,000 system gates within a 68-pin PLCC package. The device supports mixed-voltage operation with supply voltages of 3.3V or 5.0V for both core and I/Os. It operates within an industrial temperature range of -40°C to +85°C and has a maximum clock frequency of 80 MHz. The component includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable resources.

Feature Summary

• Supports mixed-voltage operation allowing compatibility with both 3.3V and 5.0V systems.
• Provides deterministic, user-controllable timing with 100% resource utilization capability.
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

• High-capacity single-chip ASIC replacement
• Industrial control systems requiring mixed-voltage interfaces
• Automotive electronics applications

Procurement Notes

Verify the specific suffix '3' indicates the industrial temperature grade (-40°C to +85°C) and speed bin against official datasheets. Confirm package integrity upon receipt as the device is moisture sensitive. Ensure ESD precautions are followed during handling and storage to maintain component reliability.

Selection Notes

Select this model when an industrial temperature range is required alongside mixed-voltage I/O support. Compare logic density and pin count against similar MX series variants like the A40MX02 if lower gate counts suffice. Verify that the 68-pin PLCC footprint matches the target PCB design constraints.

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 high reliability for embedded logic applications.

Replacement Considerations

Direct substitutes include other MX series parts such as A40MX02 or A40MX04 variants with different packages. Verify pin compatibility and logic capacity before swapping. No alternative part numbers are confirmed without checking specific package and speed grade requirements.
