A40MX02-PLG68

Overview

The A40MX02-PLG68 is a field-programmable gate array from the Microchip MX series, featuring approximately 3K system gates and 295 logic elements. It provides 57 I/O pins within a PLCC-68 surface-mount package. The device operates on dual voltage supplies of 3.3 V or 5 V, with specified ranges of 4.5 V to 5.5 V for the 5V variant. It supports an industrial temperature range from -40°C to +85°C. The component utilizes flash-based non-volatile technology, eliminating the need for external configuration memory.

Feature Summary

• Flash-based architecture enabling instant-on functionality without external configuration devices
• In-system programmability allowing design updates via standard serial interfaces
• Supports both 3.3 V and 5 V power supply domains for flexible interface compatibility

Applications

• Industrial control systems requiring reliable logic processing in harsh environments
• Embedded communication protocol conversion and bridging applications
• General-purpose digital logic replacement in legacy hardware designs

Procurement Notes

Verify the specific suffix against official datasheets, as variations such as -I (industrial) or -1/-2 (speed grades) define electrical characteristics. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the PLCC-68 footprint matches the target PCB layout constraints before procurement.

Selection Notes

Select this model when 3K system gates and 57 I/Os are sufficient for the design. Compare speed grades if timing constraints exceed the base model capabilities. Verify that the 3.3 V or 5 V operating voltage aligns with the system power rails. Consider the PLCC-68 package availability relative to other pin counts like PLCC-44 if fewer I/Os are needed.

Part Context

This component belongs to the Actel MX family, now under Microchip Technology. The MX series is characterized by its low-power flash FPGA architecture. It serves as a drop-in replacement for complex discrete logic and PAL/GAL devices in various embedded applications.

Replacement Considerations

Check for updated speed grade suffixes such as A40MX02-1PLG68 or A40MX02-2PLG68 for different performance levels. Verify pin-to-pin compatibility with older Actel part numbers before substitution.
