A42MX24-PQ160A

Overview

The A42MX24-PQ160A is a high-performance Field Programmable Gate Array (FPGA) from Microchip Technology's MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 logic elements within a 160-pin PQFP package. The device supports dual voltage operation at 3.3V and 5V, with an operating temperature range of -40°C to +125°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and deterministic user-controllable timing. It integrates IEEE Standard 1149.1 JTAG boundary scan testing and unique in-system diagnostic capabilities via Silicon Explorer II.

Feature Summary

• Single-chip ASIC alternative architecture supporting up to 100% resource utilization and pin fixing
• Deterministic, user-controllable timing with fast wide-decode circuitry for ease of integration
• Unique in-system diagnostic capability enabled by Silicon Explorer II technology
• Supports ASIC design methodologies with synthesis-friendly architecture

Applications

• Automotive electronic systems requiring robust programmable logic
• ASIC prototyping and low-volume production replacements
• Industrial control systems needing deterministic timing and diagnostics

Procurement Notes

Verify the specific suffix 'A' indicates automotive grade qualification (-40°C to +125°C). Confirm RoHS compliance status as some variants may differ. Check for End-of-Life notifications or discontinuance notices from Microchip, as older MX series parts are frequently phased out. Ensure supply chain sources provide genuine components with proper traceability.

Selection Notes

Select this model when automotive temperature ranges and 5V compatibility are required alongside 36K gate density. Compare against A42MX24-2PQG160I for industrial grade options if wider temperature ranges are not needed. Consider package availability, as PQFP160 may have limited new stock compared to BGA alternatives in the same family.

Part Context

This component belongs to the Microchip A42MX24 series, part of the broader Actel/Microchip MX FPGA portfolio. It shares architectural similarities with other A42MX devices but offers specific I/O counts and package configurations tailored for complex logic applications. The 'A' suffix typically denotes extended temperature ratings suitable for harsh environments.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to EOL status. Consider A42MX24 variants with different packages (e.g., BGA) if form factor allows. Verify functional equivalence with newer Microchip PolarFire or IGLOO2 families for long-term sustainability, though these require design migration.
