A42MX09-PL84M

Overview

The A42MX09-PL84M is a field-programmable gate array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative for automotive applications. It features 14,000 system gates and supports mixed-voltage operation with supply voltages ranging from 3V to 3.6V or 4.75V to 5.25V. The device is housed in an 84-pin PLCC package and operates within a commercial temperature range of 0°C to 70°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and support for up to 100% resource utilization and pin fixing.

Feature Summary

• Provides deterministic, user-controllable timing suitable for ASIC design methodologies
• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables unique in-system diagnostic capability through Silicon Explorer II
• Facilitates ease of integration with synthesis-friendly architecture

Applications

• Single-chip ASIC replacement for automotive electronic control units
• Prototyping and low-volume production of custom logic circuits
• Systems requiring deterministic timing and high resource utilization

Procurement Notes

Verify component authenticity against Microchip Technology standards due to potential obsolescence risks associated with legacy FPGA families. Confirm that the specific suffix corresponds to the intended voltage and temperature grade. Ensure compliance with RoHS and REACH regulations as documented in the official datasheet. Check for any active Product Change Notifications (PCNs) affecting assembly sites or material composition prior to procurement.

Selection Notes

Select this model when a compact 84-pin form factor is required alongside 14,000 system gates. Consider the mixed-voltage capability if the design interface requires both 3.3V and 5V signaling without level shifters. Verify that the commercial temperature range meets the operational environment requirements. Evaluate the available SRAM resources against the specific memory allocation needs of the target application logic.

Part Context

This component belongs to the A42MX family of FPGAs, which are positioned as cost-effective alternatives to application-specific integrated circuits. The MX series emphasizes ease of integration and deterministic performance. The A42MX09 variant specifically targets applications needing moderate logic density with flexible I/O configurations in a small footprint.

Replacement Considerations

Publicly confirmed substitute part numbers for the A42MX09-PL84M are not available in the provided documentation. Designers should consult Microchip Technology for current lifecycle status and recommended migration paths to newer FPGA families.
