• Enables 100% resource utilization and complete pin locking capabilities

Applications

• Single-chip ASIC replacement for automotive applications
• High-density digital logic integration
• Systems requiring mixed-voltage interface compatibility

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence status. Confirm specific suffix variations against official datasheets as they may indicate distinct environmental ratings or packaging types. Ensure compliance with RoHS and REACH regulations relevant to the manufacturing date and region of deployment.

Selection Notes

Select this model when 36,000 system gates and 150 I/Os are required within a 176-pin footprint. Consider the MX series architecture for synthesis-friendly designs that support standard ASIC methodologies. Evaluate thermal performance and power consumption profiles against the specific operating temperature range requirements of the target application environment.

Part Context

This component belongs to the Microsemi Actel MX family of FPGAs, which are designed as single-chip ASIC alternatives. The family spans capacities from 3,000 to 54,000 system gates, offering configurable dual-port SRAM and fast wide-decode circuitry. These devices are characterized by low power consumption and support for IEEE 1149.1 JTAG boundary scan testing.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided documentation. Verify cross-compatibility with other MX series devices such as A42MX24 variants in different packages only if electrical parameters and pinouts match exactly.
