A42MX16-PQ160

Overview

The A42MX16-PQ160 is a Field Programmable Gate Array (FPGA) belonging to the Microchip MX family. It features 24,000 system gates and 608 Logic Elements (LEs). The device provides 125 user-programmable I/O pins within a 160-pin PQFP package. Operating voltage ranges from 4.5 V to 5.5 V. It supports an industrial temperature range of -40°C to +125°C. Key performance metrics include a maximum clock frequency of 250 MHz, 5.6 ns clock-to-out delay, and up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage operation capability with PCI-compliant I/Os for core and peripheral interfaces
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• In-system diagnostic and verification capability utilizing Silicon Explorer II technology

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• Digital Signal Processing (DSP) acceleration functions
• Co-processor applications in embedded systems

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding assembly site changes or software updates. Review Moisture Sensitivity Level (MSL) handling requirements prior to PCB assembly to ensure proper storage and reflow conditions are maintained.

Selection Notes

Select this model for designs requiring high-density logic in a plastic QFP package. Ensure supply chain availability as specific suffixes may indicate end-of-life status. Compare against the A42MX16-PQG160A variant for potential packaging differences. Verify that the 125 I/O count meets interface requirements before finalizing the bill of materials.

Part Context

This component is part of the broader 40MX and 42MX FPGA families offered by Microchip Technology. These devices are designed to replace complex discrete logic solutions. The MX series emphasizes cost-effective design solutions at 5V while providing high performance to shorten system development cycles compared to traditional programmable logic devices.

Replacement Considerations

Public documentation indicates the A42MX16-PQG160A as a related variant within the same family. Verify functional equivalence and package compatibility before substitution. Check official discontinuation notices for current stock availability and long-term sourcing options.
