A42MX16-2TQ176I

Overview

The A42MX16-2TQ176I is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, housed in a 176-LQFP surface-mount package. It provides 608 Logic Elements and 24,000 system gates. The device supports mixed-voltage operation with supply voltages ranging from 3V to 3.6V and 4.5V to 5.5V. It features 140 user-programmable I/O pins and operates within a commercial temperature range of -40°C to +85°C. The component has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.
• Enables up to 100% resource utilization and pin locking for deterministic timing.
• Includes configurable dual-port SRAM for high-speed data buffering.

Applications

• High-speed controllers
• Address decoding logic
• Peripheral bus interfaces

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the package type matches the 176-LQFP form factor. Check current availability status as MX series components may have limited production runs. Ensure ESD handling protocols are followed during assembly due to CMOS technology.

Selection Notes

Select this model when 24,000 system gates and 140 I/Os are required in a compact QFP footprint. Compare against the A42MX16-2PQG176I if ceramic packaging or higher reliability certifications are needed. Verify voltage requirements match the 3.3V or 5V design constraints before finalizing the bill of materials.

Part Context

This part belongs to the Microsemi 40MX and 42MX FPGA families, designed as single-chip ASIC alternatives. These devices consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. The family offers high performance with fast wide-decode circuitry and up to 2.5 kbits of configurable dual-port SRAM.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided documentation. Designers should consult official Microchip replacement guides for legacy MX series components.
