A40MX04-PQG100

Overview

The A40MX04-PQG100 is a field-programmable gate array (FPGA) from the Microchip Technology MX series. It features 295 configurable logic blocks (CLBs) and approximately 2,000 system gates. The device supports up to 69 user-programmable I/O pins and operates with supply voltages of 3.3 V or 5 V. It is housed in a 100-pin PQFP package. Maximum clock frequency reaches 48.24 MHz with a CLB delay of 3.72 ns. Operating temperatures range from -55°C to +125°C for industrial/military grades.

Feature Summary

• Non-volatile flash-based architecture eliminates configuration memory requirements.
• Supports both 3.3 V and 5 V power supply domains for flexibility.
• Includes dual-port SRAM for high-speed data buffering applications.

Applications

• Industrial control systems requiring deterministic logic timing.
• Automotive electronics operating under extended temperature conditions.
• Military aerospace platforms demanding MIL-STD-883 compliance.

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm voltage and temperature ratings. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Check for active status as legacy parts may face end-of-life notices. Ensure ECAD models match the exact package variant.

Selection Notes

Compare CLB count and I/O availability against design requirements. Evaluate speed grade (-1 vs -2 vs -3) for timing closure. Consider package options like PLCC or QFP based on board space. Verify compatibility with Actel Libero software tools for programming.

Part Context

This component belongs to the A40MX family, designed as a single-chip ASIC alternative. It bridges the gap between complex CPLDs and larger FPGAs. The family emphasizes low power consumption and instant-on capability due to its flash technology base.

Replacement Considerations

Direct substitutes include other A40MX variants with different packages or speed grades. Cross-reference pinouts when selecting PQFP versus PLCC alternatives. Verify functional equivalence if migrating from older Actel-branded components.
