A42MX24-1PLG84M

Overview

The A42MX24-1PLG84M is a Field Programmable Gate Array from the Microchip MX Automotive family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 Logic Elements within a PLCC-84 package. The device operates on a 5V supply voltage with a range of 4.5V to 5.5V. It supports mixed-voltage operation for core and I/Os at 3.3V or 5.0V. The component has an operating temperature range from -55°C to +125°C and includes up to 72 user-programmable I/O pins.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V systems
• Provides deterministic, user-controllable timing suitable for precise design methodologies
• Enables up to 100% resource utilization and pin fixing for complete design control

Applications

• Automotive electronic systems requiring high reliability
• Single-chip ASIC replacement designs
• Industrial control applications

Procurement Notes

Verify the specific suffix M indicates military temperature grade when sourcing. Confirm RoHS compliance status as it varies by manufacturing batch and date code. Check for End-of-Life notices as this component series may be discontinued. Ensure the supplier provides valid traceability documentation for automotive-grade requirements.

Selection Notes

Select this model for designs requiring 36,000 system gates in a compact PLCC-84 footprint. Compare against other A42MX24 variants if different package types like PQFP or BGA are preferred. Verify that the 72 I/O count meets interface requirements. Consider thermal management capabilities given the wide industrial and military temperature specifications.

Part Context

This part belongs to the Microchip MX FPGA family, originally developed by Actel before acquisition. The series targets automotive and industrial markets with radiation-hardened and high-reliability options. It serves as a direct drop-in replacement for older Actel logic devices in existing designs.

Replacement Considerations

Direct substitutes include other A42MX24 variants with different packages such as A42MX24-PQ208A or A42MX24-PL84A. Cross-reference pinouts carefully when changing package types. Verify that speed grades match timing constraints if upgrading from slower variants.
