A42MX24-1PLG84I

Overview

The A42MX24-1PLG84I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with 5.0V or 3.3V core and I/Os, offering PCI-compliant interfaces. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The component utilizes a Plastic Leaded Grid Array (PLGA) package with 84 terminals, supporting deterministic timing and user-controllable delays.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 5.0V or 3.3V levels
• Provides deterministic, user-controllable timing for precise integration
• Enables up to 100% resource utilization and pin locking capabilities

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Systems utilizing PCI-compliant I/O interfaces
• Designs requiring deterministic timing control

Procurement Notes

Verify the specific suffix 'PLG' against official datasheets to confirm the Plastic Leaded Grid Array package type. Confirm RoHS compliance status as it varies by manufacturer revision. Check for discontinuance notifications from Microchip Technology regarding this specific part number before procurement planning.

Selection Notes

Select this model when 36,000 system gates and 912 CLBs are required in an 84-pin grid array format. Ensure the design accommodates mixed-voltage requirements if using 3.3V or 5.0V I/Os. Verify that the PLGA package footprint matches the PCB layout constraints compared to similar PLCC or PQFP variants.

Part Context

This component belongs to the A42MX series of FPGAs manufactured by Microchip Technology, formerly Actel. The series is characterized by flash-based technology suitable for low-power and high-reliability applications. The A42MX24 variant specifically targets mid-range logic density needs within the automotive and industrial sectors.

Replacement Considerations

Check for direct substitutes within the A42MX family such as A42MX24-PL84A or A42MX24-PL84I, ensuring package compatibility. Verify if newer Microchip FPGA families offer equivalent gate counts with improved performance metrics.
