A42MX24-3PLG84I

Overview

The A42MX24-3PLG84I is a Field Programmable Gate Array from the Microchip MX Automotive Family. It features 36,000 system gates and 912 Adaptive Logic Modules (ALMs). The device operates within a voltage range of 4.75 V to 5.25 V and supports an industrial temperature range of 0°C to +70°C. It utilizes a PLCC-84 surface-mount package with 72 I/O pins. The architecture includes fast wide-decode circuitry and supports deterministic timing.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Deterministic, user-controllable timing
• Supports up to 100% resource utilization and pin fixing

Applications

• Automotive electronic control units
• Industrial automation controllers
• High-reliability logic replacement

Procurement Notes

Verify the specific suffix 'I' against official datasheets to confirm industrial temperature rating compliance. Confirm RoHS status and lead-free designation through current manufacturer documentation. Check for product discontinuation notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when deterministic timing and high pin-fixing capabilities are required for automotive or industrial designs. Ensure the design accommodates the 5V core voltage requirements and PLCC-84 footprint constraints compared to lower-density variants in the A42MX series.

Part Context

This part belongs to the A42MX family, designed as a radiation-tolerant, single-chip ASIC alternative. It bridges the gap between discrete logic and complex FPGAs, offering high integration density with predictable performance characteristics suitable for safety-critical systems.

Replacement Considerations

Direct replacements include other speed grades within the A42MX24 series such as A42MX24-1PLG84I or A42MX24-2PLG84I, provided timing requirements are met. Verify package compatibility and thermal specifications before substitution.
