A42MX24-1PQ160

Overview

The A42MX24-1PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 1890 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with 5.0V or 3.3V core and I/Os, including PCI-compliant I/Os. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The component operates within a commercial temperature range of 0°C to +70°C and utilizes a 160-pin PQFP package.

Feature Summary

• Supports up to 100% resource utilization and 100% pin locking for deterministic timing.
• Includes unique in-system diagnostic capability with Silicon Explorer II.
• Features IEEE Standard 1149.1 (JTAG) boundary scan testing and verification.

Applications

• Single-chip ASIC replacement for automotive applications
• Programmable logic integration requiring deterministic timing
• Systems utilizing JTAG boundary scan testing

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard datasheets typically list variants like -1PQG160 or -2PQG160I. Confirm current production status, as the A42MX series has faced obsolescence notices. Ensure compatibility with existing PCB footprints for the 160-pin PQFP package before procurement.

Selection Notes

Select this model for designs requiring 36K system gates with mixed 3.3V/5.0V I/O capabilities. Consider the -1 speed grade if lower performance thresholds are acceptable compared to higher grades. Verify that the 160-pin PQFP package fits the mechanical constraints and that the commercial temperature range meets the operational environment requirements.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between CPLDs and high-end FPGAs. The A42MX24 variant specifically offers 36,000 system gates, positioning it for medium-complexity logic applications. The family is known for non-volatile SRAM technology, allowing instant-on functionality without external configuration memory.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in the provided source material. Consult Microchip's official obsolescence notices or engineering change orders for potential recommended replacements within the MX family.
