A42MX09-3PLG84I

Overview

The A42MX09-3PLG84I is a Field Programmable Gate Array (FPGA) belonging to the MX series, manufactured by Microchip Technology. It features 336 Logic Elements and 14,000 system gates. The device provides 72 Input/Output terminals and operates within a supply voltage range of 4.5 V to 5.5 V. It supports surface mount installation in a PLCC-84 package. The component is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Utilizes non-volatile flash-based technology for instant-on functionality without external configuration memory.
• Supports mixed voltage I/O interfaces compatible with both 3.3V and 5V logic levels.
• Integrates high-density programmable logic suitable for complex digital control applications.

Applications

• Industrial automation control systems
• Automotive electronic modules
• Telecommunications interface circuits

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the PLCC-84 package dimensions and pinout match the design requirements. Check for RoHS compliance status as manufacturing processes may vary. Ensure the source document explicitly lists this exact part number to avoid confusion with similar MX series variants.

Selection Notes

Select this component when a flash-based FPGA with moderate logic density is required. The MX series offers reprogrammability with non-volatile storage. Compare the 336 LE count against project complexity. Verify that the 72 I/O pins meet interface needs. Consider the PLCC-84 package availability for PCB layout constraints.

Part Context

This part belongs to the Microchip MX FPGA family, originally developed by Actel before its acquisition. The MX series is characterized by its use of anti-fuse or flash technology, providing robust security and low power consumption compared to SRAM-based FPGAs. It serves as a drop-in replacement for many legacy CPLD designs requiring higher performance.

Replacement Considerations

Check for direct cross-references within the same MX family, such as A42MX09 variants with different packages. Verify if newer Microchip PolarFire or IGLOO2 series parts offer functional compatibility with improved performance metrics.
