A42MX24-PLG84I

Overview

The A42MX24-PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX family, housed in an 84-pin PLCC package. It features 36,000 system gates and 912 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core and I/O supplies of 3.3V or 5.0V, operating within a commercial temperature range of -40°C to +85°C. Key specifications include up to 176 user-programmable I/O pins, deterministic timing, and IEEE 1149.1 JTAG boundary scan support.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Mixed-voltage operation supporting 3.3V or 5.0V core and I/Os
• Deterministic, user-controllable timing with fast wide-decode circuitry
• Supports up to 100% resource utilization and pin fixing

Applications

• Automotive electronic control units
• Industrial automation controllers
• Communication interface adapters

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status as variants exist. Check for End-of-Life notifications or discontinuance notices prior to procurement. Ensure ESD handling protocols are followed during storage and assembly.

Selection Notes

Select this model for designs requiring high gate density in a plastic leaded chip carrier package. Compare against A42MX24-PL84I for specific temperature grade requirements. Evaluate pin count compatibility with existing PCB footprints. Consider power consumption differences between 3.3V and 5.0V operating modes.

Part Context

Part of the A42MX series offering 3,000 to 54,000 system gates. Shares architecture with A40MX and A42MX families. Designed for low-power, high-reliability applications. Compatible with Actel design tools and synthesis flows.

Replacement Considerations

A42MX24-PL84I is a verified functional substitute within the same package and gate count family. Verify temperature range and voltage specifications match application requirements before substitution.
