A42MX16-1TQ176

Overview

The A42MX16-1TQ176 is a Field Programmable Gate Array (FPGA) belonging to the Microsemi MX family. It features 24,000 system gates and 608 Logic Elements within a 176-pin Thin Quad Flat Package (TQFP). The device supports mixed-voltage operation with supply voltages ranging from 3V to 3.6V and 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

• High-capacity single-chip ASIC alternative providing consolidation for multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.
• Features fast wide-decode circuitry and high-speed clock-to-out performance.
• Enables 100% resource utilization and pin locking with deterministic timing.

Applications

• High-speed controllers and address decoding logic.
• Peripheral bus interface implementations.
• DSP and co-processor functions.

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or official channels. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Check for specific revision markings on the device surface to ensure compatibility with design requirements.

Selection Notes

Select this model when 24,000 system gates and 176 available I/O pins are required in a TQFP form factor. Ensure voltage levels match the 3.3V or 5.0V core specifications. Consider thermal dissipation capabilities inherent to the plastic QFP package for the target application environment.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which offer cost-effective design solutions at 5V. These devices provide high performance while shortening system design and development cycles by integrating complex logic onto a single chip.

Replacement Considerations

Compatible substitutes include other variants within the A42MX16 series, such as A42MX16-1TQ176I or A42MX16-2TQG176, provided temperature ranges and speed grades align with the original design specifications.
