A42MX16-2PQ160I

Overview

The A42MX16-2PQ160I is a Flash-based Field Programmable Gate Array from the Microchip MX Automotive family, designed as a single-chip ASIC alternative for automotive applications. It features 24,000 system gates and 608 Logic Elements within a PQFP-160 package. The device supports 125 I/Os and operates on a 5V supply voltage with a range of 4.75V to 5.25V. It functions within an industrial temperature range of -40°C to +125°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, deterministic timing, and support for IEEE Standard 1149.1 JTAG boundary scan testing.

Feature Summary

• Single-chip ASIC alternative architecture supporting up to 100% resource utilization and pin fixing
• Deterministic, user-controllable timing suitable for safety-critical designs
• Unique in-system diagnostic capability utilizing Silicon Explorer II technology
• Low power consumption CMOS process optimized for automotive environments

Applications

• Automotive electronic control units requiring ASIC replacement
• Industrial motor control systems
• Safety-critical logic implementation with deterministic timing requirements

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners due to potential counterfeit risks in the aftermarket. Confirm RoHS compliance status and moisture sensitivity level (MSL) handling requirements prior to assembly. Review official Product Change Notices (PCNs) for any recent manufacturing or packaging updates that may affect compatibility or lead times.

Selection Notes

Select this model when a 5V tolerant interface is required alongside high I/O density in a QFP package. Ensure the design utilizes the specific 24K gate capacity efficiently given the fixed pin count. Compare against the A42MX series variants if different temperature grades or package sizes are needed for space-constrained automotive PCB layouts.

Part Context

This component belongs to the Actel MX Automotive FPGA family, now manufactured by Microchip Technology following their acquisition of Actel. The series is distinguished by its non-volatile Flash technology, which eliminates the need for external configuration memory commonly found in SRAM-based FPGAs. This integration reduces board space and enhances reliability in harsh automotive environments.

Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Consider the A42MX16-2PQG160I for equivalent performance in a QFN variant, though pinout differences exist. For legacy Actel parts, verify functional equivalence carefully as architectural differences between Flash and other FPGA technologies may require significant design rework.
