A40MX02-3PL68

Overview

The A40MX02-3PL68 is a Field Programmable Gate Array from the Microchip Technology MX series, housed in a 68-pin PLCC package. It provides 295 Logic Elements and approximately 3,000 system gates. The device supports mixed-voltage operation with supply voltage ranges of 4.5 V to 5.5 V for 5V core/I/O configurations or 3.0 V to 3.6 V for 3.3V configurations. It features 57 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. The architecture utilizes fast wide-decode circuitry and includes up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V logic levels.
• Features deterministic timing through user-controllable pin locking and resource utilization.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II technology.

Applications

• High-capacity single-chip ASIC replacement
• Mixed-voltage interface bridging between different logic families
• Industrial control systems requiring deterministic timing

Procurement Notes

Verify the specific suffix against official datasheets, as variants like A40MX02-3PL68I denote industrial temperature ranges while others may differ. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with the intended programming toolchain and verify that the 68-pin PLCC footprint matches the design constraints.

Selection Notes

Select this component when a low-gate-count FPGA with mixed-voltage I/O support is required. Compare against the A40MX04 series if higher gate counts are needed. Consider the A40MX02-VQG80M variant if a QFP package is preferred over PLCC. Verify that the 295 LE capacity meets the design complexity without excessive overhead.

Part Context

This part belongs to the Actel (now Microchip) MX family of flash-based FPGAs. These devices are known for non-volatile configuration and low power consumption. The A40MX02 represents the entry-level density within the 40MX series, offering a balance of logic resources and I/O flexibility for simple embedded applications.

Replacement Considerations

Direct substitutes include other members of the A40MX02 family such as A40MX02-1PLG68 or A40MX02-2PLG68, depending on speed grade and temperature requirements. Cross-family replacements like Lattice MACH XO or Intel MAX 10 require significant redesign due to architectural differences.
