A42MX16-3TQ176

Overview

The A42MX16-3TQ176 is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a high-capacity single-chip ASIC alternative. It features 24,000 system gates and 608 Logic Elements within a 176-pin Thin Quad Flatpack (TQFP) package. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V or 4.5V to 5.5V. It 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 operation for PCI-compliant interfaces
• Provides deterministic, user-controllable timing with up to 100% pin locking
• Integrates configurable dual-port SRAM for fast data access

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm moisture sensitivity level handling requirements during storage and assembly. Review manufacturer notifications for specific lot traceability and final purchase dates to ensure supply chain compliance.

Selection Notes

Select this model for designs requiring 24,000 system gates in a 176-pin TQFP form factor. Ensure voltage levels match the 3.3V or 5V core specifications. Consider the commercial temperature range (-40°C to 85°C) against application thermal profiles before finalizing the part number.

Part Context

This component belongs to the Microsemi 40MX and 42MX FPGA families, which serve as cost-effective replacements for multiple PALs, CPLDs, and FPGAs. The series is characterized by high performance and shortened development cycles, consolidating logic into a single chip solution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing design files if considering migration to newer Microsemi FPGA architectures.
