A42MX24-PQG160I

Overview

The A42MX24-PQG160I is a non-volatile Field Programmable Gate Array from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 logic elements within a PQFP-160 package. The device supports dual voltage operation with a minimum supply of 4.75 V and maximum of 5.25 V, alongside a 3.3 V option. It includes up to 2.5 kbits of configurable dual-port SRAM and offers 125 I/Os. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Non-volatile architecture enabling instant-on functionality without external configuration memory.
• Supports deterministic timing with user-controllable delays and unique in-system diagnostic capabilities.
• Designed for high reliability in harsh environments, suitable for automotive and industrial use cases.

Applications

• Automotive electronic control units requiring robust programmable logic.
• Industrial automation systems needing deterministic timing and diagnostics.
• Aerospace and defense applications demanding radiation tolerance and reliability.

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and check for Product Change Notifications regarding manufacturing site updates. Ensure proper handling for moisture sensitivity level 3 components during storage and reflow soldering processes.

Selection Notes

Select this model when non-volatile configuration and instant-on capability are required. Compare gate counts against A42MX09 or A42MX16 variants if resource constraints exist. Verify package compatibility with the PQFP-160 footprint and ensure voltage levels match the 4.75V to 5.25V operational range.

Part Context

This part belongs to the Actel MX family, now under Microchip Technology. It represents a transition from traditional volatile FPGAs by integrating flash-based non-volatile memory directly into the fabric. This allows for reduced bill-of-materials by eliminating external configuration chips commonly found in other FPGA architectures.

Replacement Considerations

Direct replacements include A42MX24-2PQG160I for higher speed grades within the same package. Cross-family migration to Microchip PolarFire or Igloo series may be necessary for advanced features, though pinouts and toolchains will differ significantly.
