A42MX09-2PQ100

Overview

The A42MX09-2PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip Technology MX family, housed in a PQFP-100 package. It features 336 Logic Elements and approximately 14,000 system gates. The device supports mixed-voltage operation with core and I/O supplies of 5.0V or 3.3V. Key electrical parameters include a maximum clock frequency of 70.2 MHz and a CLB maximum combinational delay of 3.5 ns. It offers up to 104 user-programmable I/O pins and includes configurable dual-port SRAM resources. Operating temperatures range from -40 °C to +85 °C for industrial applications.

Feature Summary

• Provides high-capacity single-chip ASIC alternative capabilities with up to 54,000 system gates across the family.
• Supports mixed-voltage operation allowing 5.0V or 3.3V configurations for both core and I/Os.
• Features deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix against official datasheets to confirm temperature grade and package variant. Ensure compatibility with existing PCB footprints for the PQFP-100 form factor. Confirm RoHS compliance status for the specific manufacturing lot. Check for any recent Product Change Notifications regarding assembly sites or material updates.

Selection Notes

Select this component when a cost-effective solution replacing multiple PALs, CPLDs, or FPGAs is required. Consider the A42MX09 for designs needing deterministic timing and mixed-voltage I/O support. Evaluate the 14,000 gate count against logic complexity requirements. Verify that the 70.2 MHz performance meets signal processing speed needs.

Part Context

This part belongs to the 40MX and 42MX FPGA families originally developed by Actel and acquired by Microchip Technology. These devices are designed as single-chip solutions to shorten system design cycles. The family integrates high-performance logic with configurable memory resources for versatile embedded applications.

Replacement Considerations

Direct substitutes within the same package and functionality may include other variants from the A42MX series, such as the A42MX16, provided gate counts and I/O requirements align. Cross-referencing with the A40MX series is possible for lower-density needs. Always verify pin-to-pin compatibility and electrical specifications before substitution.
