A40MX04-FPQG100

Overview

The A40MX04-FPQG100 is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 295 configurable logic blocks and approximately 6,000 system gates. The device supports mixed-voltage operation with supply voltages of 3V to 3.6V or 4.75V to 5.25V. It utilizes a 100-pin PQFP package and operates within a commercial temperature range of 0°C to 70°C. The component includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable constraints.

Feature Summary

• Supports mixed-voltage core and I/O operations compatible with PCI standards
• Provides deterministic, user-controllable timing for precise design implementation
• Enables 100% resource utilization and complete pin locking capabilities

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-signal interface bridging between different voltage domains
• Complex state machine implementations requiring deterministic timing

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard listings often use -1PQG100 or -CQ100I. Confirm moisture sensitivity level and RoHS compliance status directly with the manufacturer before procurement. Ensure the specific variant matches the required temperature grade and package tolerance for your application.

Selection Notes

Select this component when designing systems requiring moderate logic density with mixed-voltage I/O support. Verify that the 100-pin PQFP package fits the board layout constraints. Consider the 0°C to 70°C operating range; if wider temperature ranges are needed, check for industrial or military variants within the same family.

Part Context

This part belongs to the Actel/Microchip MX FPGA family, known for non-volatile flash-based technology. It serves as a drop-in replacement for complex programmable logic devices (CPLDs) and small ASICs. The family emphasizes low power consumption and high reliability for embedded control applications.

Replacement Considerations

Direct substitutes include other MX series parts like A40MX02 or A40MX08 depending on gate count requirements. Cross-reference pinouts carefully, as package variations exist within the family. Verify software toolchain compatibility with current Actel Libero versions.
