A40MX02-3PLG68

Overview

The A40MX02-3PLG68 is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 295 configurable logic blocks (CLBs) and approximately 3,000 system gates. The device supports mixed-voltage operation with core and I/O supplies of 3.3V or 5.0V. It utilizes an SRAM-based nonvolatile architecture housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. Key electrical parameters include a maximum operating frequency of 109 MHz and a CLB maximum combinatorial delay of 1.7 ns.

Feature Summary

• Supports mixed-voltage operation for both core and I/O at 3.3V or 5.0V levels
• Provides up to 2.5 kbits of configurable dual-port SRAM resources
• Features fast wide-decode circuitry for efficient logic implementation
• Includes unique in-system diagnostic and verification capability

Applications

• High capacity single-chip ASIC replacement designs
• Mixed-voltage interface bridging applications
• Industrial control systems requiring deterministic timing
• Automotive electronic modules

Procurement Notes

Verify the specific suffix '3' indicates the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the PLCC-68 package dimensions match the design footprint. Check for moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact speed grade and voltage specifications required by the target application.

Selection Notes

Select this component when a small form factor FPGA with mixed-voltage I/O support is required. Compare the 295 CLB count against logic utilization needs. Verify that the 109 MHz speed grade meets the system clock requirements. Consider the PLCC-68 package availability and soldering profile compatibility compared to other packages in the A40MX02 series.

Part Context

This device belongs to the A40MX02 series within the broader MX FPGA family. It shares architectural similarities with variants like the A40MX02-3PGG100A but differs in pin count and package type. The series is characterized by its SRAM-based technology and focus on low power consumption relative to comparable technologies.

Replacement Considerations

Direct substitutes within the same package include the A40MX02-2PL68IX79, which offers similar logic density but may differ in speed grade and temperature range. Cross-package replacements such as the A40MX02-VQG80M require schematic and PCB layout modifications due to different pinouts.
