A42MX09-PL84I

Overview

The A42MX09-PL84I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 14,000 system gates and 336 Logic Elements within a PLCC-84 package. The device supports mixed-voltage operation with core supply voltages of 3V to 3.6V and I/O supply voltages of 4.75V to 5.25V. It operates within an industrial temperature range of -40°C to +85°C. The component includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable delays.

Feature Summary

• Supports mixed-voltage operation allowing independent configuration of core and I/O supply voltages for compatibility with 5.0V or 3.3V systems.
• Provides deterministic, user-controllable timing characteristics suitable for precise signal synchronization requirements.
• Enables 100% resource utilization and full pin locking capabilities for optimized design integration.

Applications

• Single-chip ASIC replacement in embedded control systems
• Industrial automation logic interfacing
• Automotive electronic control unit prototyping

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Check for RoHS compliance documentation as some variants may not meet current environmental standards. Confirm availability of technical support resources given the product's end-of-life notification timeline. Ensure storage conditions adhere to moisture sensitivity level 3 requirements to prevent package damage during assembly.

Selection Notes

Select this model when a robust FPGA solution with mixed-voltage tolerance is required for industrial or automotive environments. Consider the PLCC-84 package constraints for PCB layout space. Evaluate the 14,000 gate capacity against design complexity needs. Verify that the specific I/O count meets interface requirements before finalizing the selection.
