A42MX24-1TQ176

Overview

The A42MX24-1TQ176 is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 Logic Elements within a 176-pin TQFP package. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The architecture allows for up to 100% resource utilization and deterministic timing.

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% pin locking capability
• Integrates configurable dual-port SRAM for flexible memory applications

Applications

• Automotive electronic systems requiring high reliability
• Industrial control logic implementation
• Military and aerospace embedded processing

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence status. Confirm specific speed grade suffixes against official datasheets as variations exist within the MX family. Check for RoHS compliance requirements as some variants may be non-compliant. Ensure supply chain stability given the product lifecycle stage.

Selection Notes

Select this model for designs requiring 36,000 system gates in a 176-pin surface-mount package. Verify that the 176-TQFP footprint matches the PCB layout constraints. Consider thermal management requirements for the plastic package variant. Compare against other MX series devices if different gate counts or I/O configurations are needed.

Part Context

This component belongs to the Microsemi Actel MX FPGA family, which bridges the gap between standard PLDs and complex ASICs. The MX series is known for its non-volatile SRAM technology, eliminating the need for external configuration memory. This specific part offers a balance of logic density and I/O flexibility for mid-range programmable logic applications.

Replacement Considerations

Direct substitutes include other A42MX24 variants with different speed grades or packages, such as A42MX24-1TQ176I or A42MX24-3TQ176B. Cross-family replacements from Microsemi's PolarFire or IGLOO series may require significant design re-verification.
