A42MX24-FPQ160

Overview

The A42MX24-FPQ160 is a non-volatile Field Programmable Gate Array 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 dual voltage operation at 3.3 V and 5 V, with supply ranges of 3.0–3.6 V and 4.75–5.25 V respectively. It operates within a commercial temperature range of 0°C to +70°C and includes 125 I/O pins. The architecture utilizes SRAM-based configuration stored in non-volatile flash memory.

Feature Summary

• Non-volatile flash-based architecture eliminates the need for external configuration memory.
• Supports deterministic timing with user-controllable delays and pin fixing capabilities.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.
• Provides IEEE Standard 1149.1 (JTAG) boundary scan testing and verification support.

Applications

• Automotive applications requiring single-chip ASIC alternatives.
• Industrial control systems needing deterministic timing.
• Consumer electronics utilizing low power consumption logic.
• Military and aerospace environments supporting radiation-tolerant designs.

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Review Product Change Notifications for manufacturing site updates. Ensure ECAD models match the specific PQFP-160 footprint. Validate thermal requirements against the specified operating temperature range.

Selection Notes

Select this model for designs requiring 36K system gates with non-vatile configuration. Compare I/O counts and voltage levels against target interface requirements. Consider the PQFP-160 package constraints for PCB layout. Evaluate replacement options if long-term supply continuity is critical for the product lifecycle.

Part Context

This component belongs to the Actel MX family, acquired by Microchip Technology. The A42MX24 variant represents the mid-range capacity within the series, offering 36,000 system gates. It shares architectural similarities with other MX devices but differs in gate count and I/O availability based on the specific package selected.

Replacement Considerations

Public confirmed substitute part numbers are not available. The device is listed as obsolete or end-of-life. Designers should evaluate newer Microchip FPGA families or third-party compatible devices with similar gate counts and package footprints.
