A40MX04-1PQG100I

Overview

The A40MX04-1PQG100I is a field-programmable gate array (FPGA) from the Microsemi MX family, manufactured by Microchip Technology. It features 295 configurable logic blocks (CLBs) and approximately 2000 equivalent system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It utilizes a 100-pin plastic quad flatpack (PQFP) package, specifically MO-108 standard. Operating specifications include a minimum temperature of -55°C and a maximum of 125°C for industrial/military grades, or -40°C to +85°C for commercial variants. The component is RoHS compliant and has a moisture sensitivity level of 3.

Feature Summary

• High-density single-chip ASIC alternative capability within the MX FPGA family
• Configurable dual-port SRAM architecture for flexible memory implementation
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O standards
• Deterministic timing with user-controllable pin locking and resource utilization

Applications

• Industrial control systems requiring deterministic logic processing
• Automotive electronics applications compatible with mixed-voltage interfaces
• Military and aerospace embedded systems utilizing high-reliability ceramic or plastic packages
• General-purpose programmable logic replacement for custom ASIC designs

Procurement Notes

Verify the specific suffix code against the official Microchip datasheet to confirm the exact operating temperature range and voltage variant. Ensure the ordering part number matches the required package type and speed grade. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when 295 CLBs are sufficient for the target design complexity. Consider the PQFP-100 package constraints regarding board space and thermal dissipation. Evaluate if the 48.24 MHz performance meets the system timing requirements. Compare against other MX family members like the A40MX02 or A42MX series if different gate counts or package options are needed.

Part Context

This component belongs to the Microsemi MX FPGA family, which serves as a high-capacity alternative to traditional ASICs. The family offers scalable logic resources ranging from thousands to tens of thousands of system gates. These devices are known for their fast wide-decode circuitry and support for up to 202 user-programmable I/O pins across various package types.

Replacement Considerations

Direct substitutes within the same package and electrical characteristics may include other A40MX04 variants with different speed grades or temperature ranges, such as A40MX04-1PQG100 or A40MX04-3PQG100I. Verify pin compatibility and timing parameters before substitution.
