A42MX16-1TQ176M

Overview

The A42MX16-1TQ176M is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a high-capacity single-chip ASIC alternative. It features 24,000 system gates and 295 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, ensuring PCI-compliant compatibility. Key performance metrics include a maximum clock frequency of 48.24 MHz, a CLB delay of 3.72 ns, and a 5.6 ns clock-to-out time. It integrates up to 2.5 kbits of configurable dual-port SRAM and offers up to 140 user-programmable I/O pins in a 176-LQFP package.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 3.3V or 5.0V levels.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Integrates fast wide-decode circuitry and configurable dual-port SRAM for complex logic consolidation.

Applications

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

Procurement Notes

Verify the specific suffix 'M' against official Microsemi documentation to confirm temperature range and qualification status, as standard variants may differ. Confirm RoHS compliance status, as some MX family devices are noted as non-compliant in historical records. Check for active production status or obsolescence notices prior to procurement.

Selection Notes

Select this component when a single-chip solution is required to replace multiple PALs, CPLDs, or FPGAs. Ensure the design utilizes the available 295 CLBs and 2.5 kbits of embedded memory. Verify that the 176-pin LQFP package fits the board layout constraints and that the 48.24 MHz speed grade meets the system timing requirements.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which offer system gate counts ranging from 3,000 to 54,000. These devices are engineered to shorten design cycles by consolidating logic into a single chip. The family supports commercial, industrial, automotive, and military temperature grades, with options for ceramic packages and QML certification.

Replacement Considerations

Direct substitutes within the same gate count and package include the A42MX16-1TQ176I or A42MX16-2TQ176I. Variants with different suffixes may indicate changes in temperature range or quality level rather than functional differences.
