A42MX24-2PLG84

Overview

The A42MX24-2PLG84 is a Flash-based Field Programmable Gate Array from the Microchip MX Automotive family. It features 36,000 system gates and 912 logic elements within a PLCC-84 package. The device operates at a supply voltage range of 4.75 V to 5.25 V with a standard operating voltage of 5 V. It supports up to 72 I/O pins and functions within a commercial temperature range of 0°C to +70°C. This component serves as a single-chip ASIC alternative for automotive applications.

Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration memory
• Designed as a single-chip ASIC alternative suitable for automotive applications
• Supports mixed-voltage operation with PCI-compliant I/O capabilities
• Includes deterministic timing control and user-controllable resource utilization

Applications

• Automotive electronic systems requiring robust programmable logic
• ASIC prototyping and low-volume production replacements
• Industrial control interfaces utilizing mixed-voltage signaling

Procurement Notes

This component has reached End-of-Life status. Manufacturers have issued discontinuance notifications indicating that production will cease. Verification of final shipment dates and last-time buy windows is essential before design commitment. Sourcing should focus on authorized distributors or surplus markets with strict authenticity checks due to the discontinued status.

Selection Notes

Select this part only if legacy compatibility with the Actel MX family is required. Verify that the PLCC-84 package fits the target PCB footprint. Ensure the 5V-only core voltage meets the system power budget. Consider the limited I/O count of 72 pins against interface requirements. Evaluate replacement options from newer Microchip families if new designs are permitted.

Part Context

The A42MX24-2PLG84 belongs to the A42MX24 series within the broader MX FPGA portfolio. It shares architectural similarities with other devices in the 36K gate class, such as the A42MX24-PL84A and A42MX24-PQ208A. These variants differ primarily in package type and temperature grade while maintaining equivalent logic capacity and core functionality.

Replacement Considerations

Direct pin-compatible substitutes are not publicly confirmed for this specific suffix. Review the A42MX24-PL84A for package similarity. Consult Microchip documentation for migration guides from the MX family to current FPGA architectures.
