A42MX24-2PQ160

Overview

The A42MX24-2PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 Logic Elements within a PQFP-160 package. The device supports mixed-voltage operation with I/O options for both 5V and 3.3V domains, ensuring PCI compliance. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The architecture allows for deterministic timing, 100% resource utilization, and pin locking. Standard IEEE 1149.1 JTAG boundary scan testing is supported for verification.

Feature Summary

• Supports mixed-voltage operation with 5.0V or 3.3V core and I/O configurations
• Enables 100% resource utilization and 100% pin fixing for ASIC design methodologies
• Provides unique in-system diagnostic capability via Silicon Explorer II
• Features deterministic, user-controllable timing for reliable integration

Applications

• Single-chip ASIC replacement in automotive applications
• Digital signal processing requiring deterministic timing
• Industrial control systems needing mixed-voltage I/O interfaces
• Prototyping complex logic designs with high pin counts

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Request official datasheets and RoHS compliance documentation prior to acquisition. Confirm manufacturing lot dates and storage conditions due to potential end-of-life status. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during installation and testing phases.

Selection Notes

Select this model when a high-density FPGA with mixed-voltage I/O capabilities is required for ASIC prototyping or replacement. Consider the PQFP-160 package constraints regarding board space and thermal management. Evaluate if the 36,000 gate capacity meets specific logic density requirements compared to lower-end MX variants. Verify that the 5V/3.3V compatibility aligns with existing system voltage levels.

Part Context

This component belongs to the Microchip Actel MX family of FPGAs, which bridges the gap between standard programmable logic and custom ASIC solutions. The series is known for its non-volatile SRAM technology, allowing instant-on functionality without external configuration memory. The A42MX24 variant represents a mid-to-high density option within the commercial-grade plastic package lineup, offering robust performance for complex digital designs.

Replacement Considerations

Direct substitutes include other A42MX24 variants with different packages such as A42MX24-PQG160 or A42MX24-PQ208A, provided pin compatibility is verified. Lower density alternatives like A42MX16 may suffice if logic resources are not fully utilized. Cross-family migration to newer Microchip PolarFire or SmartFusion devices requires significant architectural redesign.
