A42MX24-PQG160

Overview

The A42MX24-PQG160 is a non-volatile Flash-based Field Programmable Gate Array from the Microchip MX family. It provides 36,000 system gates and 912 logic elements within a 160-pin PQFP package. The device supports dual voltage operation at 3.3 V and 5 V, with supply rails ranging from 4.75 V to 5.25 V for 5 V mode. It features 125 I/O pins and operates within a commercial temperature range of 0°C to +70°C. This component serves as a single-chip ASIC alternative for automotive applications.

Feature Summary

• Non-volatile Flash architecture eliminates the need for external configuration memory.
• Supports deterministic timing with user-controllable delays and 100% pin fixing capabilities.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.

Applications

• Automotive electronic control units requiring high reliability.
• Industrial automation systems needing deterministic logic performance.
• Aerospace and defense avionics utilizing radiation-tolerant or high-reliability logic.

Procurement Notes

This specific part number has been officially discontinued by the manufacturer. Procurement must rely on remaining stock from authorized distributors or secondary market sources. Verify lot dates and moisture sensitivity levels carefully, as inventory age may impact soldering requirements. Ensure compatibility with existing design files before acquiring obsolete units.

Selection Notes

Select this component when a non-volatile FPGA with moderate gate density and robust I/O count is required for industrial or automotive environments. Consider the 160-pin PQFP package constraints and verify that the 3.3V/5V dual-voltage support matches the target system power rails. Evaluate thermal management needs for the commercial temperature grade.

Part Context

The A42MX24-PQG160 belongs to the Actel (now Microchip) MX series of Flash FPGAs. These devices are designed to replace complex discrete logic or custom ASICs in cost-sensitive applications. The series offers immediate power-up readiness due to its non-volatile nature, distinguishing it from volatile SRAM-based FPGAs that require external configuration PROMs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available for this discontinued model. Engineers should evaluate newer Microchip PolarFire or IGLOO2 families for functional equivalents, though pinouts and capacities will differ significantly.
