A42MX09-2PL84

Overview

The A42MX09-2PL84 is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family. It provides 14,000 system gates and 336 logic elements within a PLCC-84 package. The device supports mixed-voltage operation with a core voltage of 3.3V or 5.0V and I/O voltages of 3.3V or 5.0V. Electrical specifications include a minimum supply voltage of 4.75V and a maximum of 5.25V. The commercial temperature grade operates between 0°C and +70°C. It features up to 72 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Single-chip ASIC alternative offering deterministic timing and user-controllable delays for precise integration.
• Supports mixed-voltage operation allowing flexible interface compatibility with both 3.3V and 5.0V systems.
• Enables up to 100% resource utilization and 100% pin locking for complete design definition.

Applications

• Automotive electronic control units requiring high reliability and deterministic performance.
• Industrial automation controllers needing robust programmable logic solutions.
• Aerospace and defense systems utilizing radiation-tolerant or high-reliability FPGA architectures.

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm temperature range and package variations. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for active production status or end-of-life notifications prior to procurement planning.

Selection Notes

Select this model when 14,000 system gates are sufficient for the target logic density. Ensure the design requires the specific I/O count available in the PLCC-84 footprint. Consider the mixed-voltage capability if the system interfaces with legacy 5V components alongside modern 3.3V logic.

Part Context

This component belongs to the Microchip MX family of Flash FPGAs, originally developed by Actel. The series is characterized by non-volatile Flash technology, eliminating the need for external configuration memory. It serves as a bridge between discrete logic and complex processors in space-constrained applications.

Replacement Considerations

Direct replacements within the same family include the A42MX09-1PL84 and A42MX09-3PL84, which differ primarily in temperature grades. Cross-family migration may require evaluating the ProASIC3 or PolarFire families for updated feature sets.
