A42MX16-1PQ100M

Overview

The A42MX16-1PQ100M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with 5.0V or 3.3V core and I/Os, including PCI-compliant interfaces. Key performance metrics include a maximum clock frequency of 48.24 MHz and a CLB delay of 3.72 ns. It offers up to 2.5 kbits of configurable dual-port SRAM and supports up to 202 user-programmable I/O pins in a PQFP-100 package.

Feature Summary

• High-density logic architecture providing a cost-effective replacement for multiple PALs, CPLDs, and FPGAs.
• Integrated configurable dual-port SRAM enabling fast data buffering and FIFO applications.
• Mixed-voltage capability supporting both 5.0V and 3.3V core and I/O operations.
• Deterministic timing with user-controllable delays and 100% pin locking resources.

Applications

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

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm military temperature rating and qualification status. Ensure compatibility with existing PCB footprints for the PQFP-100 package. Check for moisture sensitivity level requirements during assembly. Confirm that the design tool version supports the specific MX family generation for accurate place-and-route results.

Selection Notes

Select this component when a moderate gate count FPGA with mixed-voltage support is required. Compare against lower-gate-count variants if resource utilization is low. Consider the PQFP-100 package constraints regarding board space and thermal dissipation. Verify that the 48.24 MHz speed grade meets the target system timing requirements.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are known for consolidating complex logic designs into single chips. The A42MX16 variant specifically targets applications needing around 2,000 system gates with significant I/O flexibility.

Replacement Considerations

Direct substitutes within the same family include A42MX16-2PQ100A for commercial/industrial grades. For higher speed requirements, check the A42MX16-1 series variants. Ensure pinout compatibility when replacing older Actel or Microsemi parts.
