A42MX16-TQ176M

Overview

The A42MX16-TQ176M is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, housed in a 176-pin TQFP package. It contains 608 Configurable Logic Blocks (CLBs) and offers approximately 24,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, compliant with PCI standards. Key electrical parameters include a maximum clock frequency of 117MHz and a CLB delay of 3.72ns. It operates within temperature ranges including -40°C to +85°C for industrial variants.

Feature Summary

• Provides high-capacity single-chip ASIC alternative capabilities with up to 54,000 system gates across the family.
• Integrates fast wide-decode circuitry and user-programmable I/O pins for flexible interface design.
• Supports deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Enables unique in-system diagnostic and verification capability through Silicon Explorer II.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP co-processor functions
• Military and aerospace systems requiring MIL-STD-883 certification

Procurement Notes

Verify the specific suffix code against official Microchip documentation to confirm temperature grade and package variant. Confirm RoHS compliance status as older revisions may not meet current environmental regulations. Check for Product Change Notifications (PCN) regarding discontinuation or manufacturing site transfers before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring dense logic in a moderate pin-count surface-mount package. Ensure voltage levels match the 3.3V or 5.0V supply rails supported by the MX family. Consider thermal dissipation requirements for the TQFP-176 package in enclosed environments.

Part Context

This part belongs to the A42MX16 series, which consolidates logic previously implemented in multiple PALs, CPLDs, and FPGAs. The MX family is known for cost-effective design solutions at 5V, shortening development cycles while providing high performance for complex digital applications.

Replacement Considerations

Direct substitutes include other parts within the A42MX16 series with compatible packages, such as A42MX16-2TQG176M. Verify pinout compatibility and electrical specifications before swapping components in existing designs.
