A40MX02-3VQ80

Overview

The A40MX02-3VQ80 is a Field Programmable Gate Array (FPGA) from the Microchip Technology 40MX family. 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 5.0V or 3.3V. It utilizes SRAM-based non-volatile configuration technology and includes up to 2.5 kbits of configurable dual-port SRAM. The component is housed in an 80-pin VQFP package.

Feature Summary

• Supports mixed-voltage operation for both core logic and I/O pins at 5.0V or 3.3V levels
• Includes configurable dual-port SRAM for embedded memory applications
• Features fast wide-decode circuitry for efficient address decoding
• Enables deterministic timing through user-controllable clock management

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-signal interface bridging between different voltage domains
• Prototyping for complex digital logic systems
• Industrial control logic implementation

Procurement Notes

Verify the specific speed grade suffix against official Microchip documentation to ensure timing compliance. Confirm package availability as legacy FPGA families may have limited production runs. Check for RoHS compliance status and lead times directly with authorized distributors. Ensure ESD handling procedures are followed during storage and assembly due to the CMOS process technology.

Selection Notes

Select this model when 3,000 system gates and 295 CLBs are sufficient for the target design. Choose the VQ80 package if space-constrained surface-mount assembly on an 80-pin footprint is required. Consider the 3.3V or 5.0V mixed-voltage capability if interfacing with legacy components. Verify that the SRAM-based configuration architecture aligns with the project's reprogrammability requirements.

Part Context

This component belongs to the Actel 40MX family of SRAM-based FPGAs, originally developed by Actel Corporation before its acquisition by Microsemi and subsequently Microchip Technology. The 40MX series was designed to offer high-density logic in small packages, serving as a drop-in replacement for complex GALs and PLDs. The A40MX02 variant represents a specific gate count tier within this lineage.
