A42MX16-FPQ160

Overview

The A42MX16-FPQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a high-capacity single-chip ASIC alternative. It features 24,000 system gates and supports up to 178 user-programmable I/O pins. The device integrates configurable dual-port SRAM with fast access times and wide-decode circuitry for address decoding. It operates within mixed-voltage ranges of 3V to 3.6V or 4.5V to 5.5V, supporting PCI-compliant I/Os. The component is housed in a 160-pin FineLine PQFP package.

Feature Summary

• High-density logic capacity suitable for replacing multiple PALs, CPLDs, and FPGAs on a single chip
• Integrated configurable dual-port SRAM enabling fast data access and FIFO implementations
• Mixed-voltage operation capability allowing flexible interface integration with 3.3V and 5.0V systems
• Deterministic timing characteristics with full resource utilization and pin locking support

Applications

• High-speed controllers and peripheral bus interfaces
• Address decoding and DSP co-processor functions
• Automotive and industrial control systems requiring mixed-voltage compatibility

Procurement Notes

Verify current availability status as the A42MX16 family has been subject to discontinuation notices. Confirm specific suffix requirements against official datasheets to ensure correct voltage range and temperature grade selection. Check for Product Change Notifications regarding assembly sites or software updates before finalizing procurement plans.

Selection Notes

Select this model when design requirements exceed standard CPLD capacities but do not necessitate complex embedded processors. Ensure the 160-pin PQFP footprint fits the target PCB layout. Verify that the required I/O count remains within the 178-pin limit and that the operating voltage aligns with the specified 3V or 5V core configurations.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which are engineered for cost-effective system consolidation. These devices bridge the gap between simple programmable logic and complex FPGAs, offering deterministic performance and ease of integration through Silicon Explorer II diagnostic tools.

Replacement Considerations

Direct replacements may be limited due to discontinuation trends within the MX family. Evaluate newer Microchip PolarFire or IGLOO2 series for modern equivalents, ensuring pinout compatibility and logic density meet the original design specifications.
