A42MX16-1PQG160I

Overview

The A42MX16-1PQG160I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 608 Logic Elements and approximately 14,000 system gates within a 160-pin PQFP package. The device supports mixed-voltage operation with core voltages of 3.3V or 5V and I/O levels compatible with 5.0V systems. It includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. The component operates within an industrial temperature range of -40°C to +85°C and utilizes a surface-mount installation style.

Feature Summary

• Provides high-performance logic consolidation replacing multiple PALs, CPLDs, and FPGAs in a single chip.
• Supports deterministic timing with user-controllable constraints and 100% pin locking capabilities.
• Enables in-system diagnostic and verification through integrated Silicon Explorer II technology.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• Industrial automation control systems

Procurement Notes

Verify current availability status as this specific part number may be subject to discontinuation notices. Confirm that the 160-pin PQFP package dimensions match the target PCB footprint. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate that the 3.3V or 5V power supply requirements align with the system design specifications before procurement.

Selection Notes

Select this model when a moderate gate count with significant I/O density is required for mixed-voltage applications. The 160-pin PQFP package offers a balance between pin count and physical size for board space-constrained designs. Consider the internal SRAM capacity if data buffering or state storage is necessary without external memory components.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are engineered for cost-effective design solutions at 5V. These devices provide high performance while shortening system development cycles by integrating complex logic into a single programmable chip.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 series such as A42MX16-3PQG160I or A42MX16-1PG100, depending on speed grade and package requirements. Cross-family replacements like the A3P series may require schematic and firmware adaptation due to architectural differences.
