A40MX02-3PL68I

Overview

The A40MX02-3PL68I 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 supply ranges of 4.5 V to 5.5 V or 3.0 V to 3.6 V. It utilizes a 68-pin PLCC package and operates within an industrial temperature range of -40 °C to +85 °C. Key performance metrics include a maximum clock frequency of 109 MHz and a CLB maximum combinational delay of 1.7 ns.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 5.0V or 3.3V levels.
• Provides up to 2.5 kbits of configurable dual-port SRAM resources.
• Features fast wide-decode circuitry for efficient logic implementation.

Applications

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

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm it denotes the industrial temperature grade (-40°C to +85°C). Confirm package integrity for the 68-pin PLCC form factor. Check current RoHS compliance status and moisture sensitivity level requirements before procurement.

Selection Notes

Select this component when a low gate count FPGA with mixed-voltage capability is required. Ensure the design fits within the 295 CLB limit. Verify that the 109 MHz speed grade meets timing constraints. Compare against the A40MX02-2PL68IX79 if higher speed grades are needed.

Part Context

This part belongs to the A40MX02 series within the broader MX FPGA family. It shares architectural similarities with other variants like the A40MX04 but offers lower logic density. The device is manufactured by Microchip Technology, formerly Actel/Microsemi, focusing on non-volatile flash-based FPGA technology.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other A40MX02 variants with different speed grades or temperature ratings, such as the A40MX02-2PL68IX79. Cross-family migration requires schematic and timing verification.
