A42MX24-PLG84

Overview

The A42MX24-PLG84 is a Field Programmable Gate Array (FPGA) from the MX Automotive Family, manufactured by Microchip Technology. It features 36,000 system gates and 912 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core and I/Os operating at either 5.0V or 3.3V. It utilizes a Plastic Quad Flat Package (PLCC) with 84 pins. Key specifications include up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry for ease of integration.

Feature Summary

• Single-chip ASIC alternative designed for automotive applications
• Supports mixed-voltage operation for 5.0V or 3.3V core and I/Os
• Enables up to 100% resource utilization and pin fixing
• Provides deterministic, user-controllable timing

Applications

• Automotive electronic systems
• Industrial control embedded systems
• Bluetooth and IoT wireless terminals

Procurement Notes

Verify component authenticity through official Microchip channels or authorized distributors. Confirm RoHS compliance status as it varies by specific suffix and manufacturing date. Check for End-of-Life (EOL) notifications, as many MX family parts are discontinued. Ensure design-in documentation matches the exact PLCC-84 package variant.

Selection Notes

Select this model for designs requiring high gate density in a compact 84-pin footprint. Verify voltage requirements match the 3.3V or 5.0V mixed-voltage capability. Consider the PLCC-84 package constraints for PCB layout. Evaluate if the 36,000 gate capacity meets logic complexity needs compared to smaller variants like the A42MX09.

Part Context

This part belongs to the Actel/Microchip MX FPGA family, known for non-volatile flash-based technology. The A42MX24 represents a mid-range capacity within the series, offering a balance between logic resources and pin count. It serves as a drop-in replacement for complex discrete logic or older ASICs in automotive and industrial sectors.

Replacement Considerations

Direct substitutes may include other MX family members like A42MX24-PLG84M or A42MX24-PL84A, depending on temperature grade and RoHS status. Verify pin compatibility and logic equivalence before swapping.
