A42MX09-1TQ176

Overview

The A42MX09-1TQ176 is a high-capacity Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a single-chip ASIC alternative. It features 14,000 system gates and 104 I/O pins housed in a 176-LQFP package. The device supports mixed-voltage operation with core and I/O supplies ranging from 3V to 3.6V or 4.5V to 5.5V. It includes up to 2.5 kbits of configurable dual-port SRAM and wide-decode circuitry for efficient logic implementation. Operating temperatures range from -40°C to 85°C.

Feature Summary

• Supports mixed-voltage operation for both core and I/O domains, accommodating 5.0V or 3.3V requirements.
• Provides deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.
• Integrates unique in-system diagnostic and verification features for design validation.

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage interface bridging applications
• Systems requiring deterministic timing and pin locking

Procurement Notes

Verify the specific suffix against official documentation, as the provided model lacks the final character typically indicating speed grade or temperature range. Confirm RoHS compliance status, as variants within this family exhibit differing environmental certifications. Check current lifecycle status, as several MX series components have reached end-of-life notifications. Ensure the package type matches the target PCB footprint specifications.

Selection Notes

Select based on required gate count and I/O availability, noting that the A42MX09 offers 14,000 gates. Compare voltage ranges to ensure compatibility with system power rails, specifically checking for 3V or 5V support. Evaluate thermal requirements against the commercial (-40°C to 85°C) or industrial/military ratings. Verify package dimensions for the 176-LQFP form factor during layout planning.

Part Context

This component belongs to the Microsemi 40MX and 42MX FPGA families, which are positioned as high-density programmable logic solutions. These devices bridge the gap between standard PLDs and complex ASICs, offering flexibility in prototyping and production. The MX family is known for its non-volatile flash technology, allowing instant-on functionality without external configuration memory.
