A42MX16-3PQ160

Overview

The A42MX16-3PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX family. It features 16,000 system gates and 512 Logic Elements. The device provides 125 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM. It operates with a supply voltage range of 4.75V to 5.25V for the core and supports mixed-voltage I/O levels including 5.0V and 3.3V. The component is housed in a 160-pin PQFP package and is designed for high-performance logic consolidation.

Feature Summary

• Single-chip ASIC alternative capability for consolidating multiple PALS, CPLDs, and FPGAs
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O configurations
• High-speed performance with fast wide-decode circuitry and deterministic timing
• Supports 100% resource utilization and pin locking for design flexibility

Applications

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

Procurement Notes

Verify current availability status as the MX family has faced discontinuation notices. Confirm that the specific suffix matches required temperature grades and package variants. Check for valid PCN documentation regarding assembly site changes or software updates before procurement planning.

Selection Notes

Select this model when 16,000 system gates and 125 I/Os are required in a 160-pin form factor. Ensure the design utilizes 5V logic levels compatible with the MX series. Consider the available SRAM resources for data buffering needs. Verify that the PQFP package fits the target PCB footprint constraints.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are known for providing cost-effective solutions at 5V. The family offers high performance while shortening system design cycles. They serve as direct replacements for complex discrete logic designs.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific discontinued variant are not available in verified sources. Designers should consult official Microchip transition guides for legacy FPGA migration strategies.
