Overview

The A42MX16-PQG208M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 1184 Logic Elements and approximately 3,000 system gates within a 208-pin PQFP package. The device supports mixed-voltage operation with supply voltages of 3.3V or 5.0V for core and I/Os. It includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 202 user-programmable I/O pins. The maximum clock frequency is rated at 48.24 MHz, with a CLB delay of 3.72 ns. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, compatible with 5.0V or 3.3V systems.
• Integrates configurable dual-port SRAM for high-speed data buffering and FIFO applications.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• Single-chip ASIC alternatives for complex logic consolidation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life (EOL) notices or Product Change Notifications (PCN) regarding availability. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this model when designing systems requiring mixed-voltage compatibility between 3.3V and 5.0V domains. Consider the 208-pin PQFP package for surface-mount assembly needs. Evaluate the 1184 Logic Element count against design complexity to ensure sufficient resources for logic implementation and I/O expansion.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are designed as cost-effective single-chip solutions. These devices consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs, offering high performance while shortening system design cycles.

Replacement Considerations

Check for updated suffixes such as 'A' or 'B' indicating minor revisions within the same package. Verify if newer generation FPGAs from Microchip offer pin-compatible upgrades with enhanced performance metrics.
