A42MX16-3PQG208I

Overview

The A42MX16-3PQG208I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 912 Logic Elements and 36,000 system gates, supporting up to 2.5 kbits of configurable dual-port SRAM. The device operates with supply voltages of 3V to 3.6V or 4.75V to 5.25V and supports up to 202 user-programmable I/O pins. Packaged in a 208-pin PQFP, it ensures deterministic timing and mixed-voltage operation for robust integration.

Feature Summary

• Provides high-density logic capacity suitable for replacing multiple PALs, CPLDs, and FPGAs in a single chip solution.
• Supports mixed-voltage operation allowing flexible interface compatibility with both 3.3V and 5.0V systems.
• Includes fast wide-decode circuitry and deterministic, user-controllable timing for precise signal management.
• Offers unique in-system diagnostic and verification capabilities to streamline development cycles.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential availability constraints. Confirm that the specific suffix matches the required industrial temperature grade and package variant. Review official Product Change Notices for any manufacturing site updates or software toolchain modifications relevant to this part number 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 208-pin PQFP footprint aligns with PCB layout constraints. Verify that the target application benefits from the device's fast access times and pin-locking features compared to lower-density alternatives in the MX series.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are engineered for cost-effective, high-performance programmable logic solutions. These devices bridge the gap between simple programmable logic and complex FPGAs, offering a streamlined path for system consolidation and reduced board space consumption in embedded designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the A42MX series based on gate count and I/O requirements, ensuring compatibility with existing design tools and pin configurations before considering alternative sources.
