A40MX04-3PL68

Overview

The A40MX04-3PL68 is a field-programmable gate array (FPGA) from the Microchip MX series, designed as a high-capacity single-chip ASIC alternative. It features 6,000 system gates and 295 configurable logic blocks (CLBs). The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 57 user-programmable I/O pins. The maximum clock frequency is 109 MHz with a CLB combinational delay of 1.7 ns. It is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, suitable for surface-mount installation.

Feature Summary

• Supports mixed-voltage operation allowing core and I/Os to function at either 5.0V or 3.3V levels.
• Provides deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II technology.

Applications

• High capacity single-chip ASIC replacement
• Mixed-voltage interface circuits
• PCI-compliant I/O applications

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage range and temperature grade. Confirm package type matches the required PCB footprint. Check RoHS compliance status for environmental regulations. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity level 3 requirements.

Selection Notes

Select this model for designs requiring 6,000 system gates with PLCC-68 packaging. Compare against A40MX04-1PLG68 if industrial temperature range (-40°C to +85°C) is needed instead of commercial range. Verify I/O count requirements as the 68-pin package limits available user pins. Consider A40MX02 variants if lower gate counts suffice.

Part Context

This component belongs to the Actel/Microchip MX family of SRAM-based FPGAs. These devices bridge the gap between discrete logic and custom ASICs. The A40MX04 variant specifically targets applications needing moderate complexity with low power consumption and non-volatile configuration memory characteristics inherent to the technology.

Replacement Considerations

A40MX04-1PLG68: Industrial temperature version in same package. A40MX02-3PL68X79: Lower gate count (3,000 gates) in similar LCC-68 package. A40MX04-VQG80: Higher I/O count in VQFP-80 package.
