A42MX24-FPLG84

Overview

The A42MX24-FPLG84 is a Field Programmable Gate Array from the Microchip MX Automotive family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 Configurable Logic Blocks (CLBs). The device supports up to 2.5 kbits of configurable dual-port SRAM and operates with mixed-voltage I/Os at 5.0V or 3.3V. It utilizes fast wide-decode circuitry and offers deterministic timing. The component is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package.

Feature Summary

• Single-chip ASIC alternative capability for automotive applications
• Mixed-voltage operation supporting 5.0V or 3.3V core and I/Os
• Deterministic, user-controllable timing architecture
• Support for up to 100% resource utilization and pin fixing

Applications

• Automotive electronic control units
• ASIC prototyping and low-volume production
• Industrial logic control systems

Procurement Notes

Verify the specific suffix 'FPLG84' against official Microchip documentation, as standard listings often use 'PL84'. Confirm RoHS compliance status, as some variants are non-compliant while others are compliant. Check for End-of-Life notifications or discontinuance notices, as older FPGA families may have limited availability or require factory special orders.

Selection Notes

Select this model when 36,000 system gates and an 84-pin PLCC package are required. Ensure the design leverages the deterministic timing features for critical path management. Verify that the mixed-voltage I/O requirements align with the 3.3V or 5.0V supply options available in the MX family.

Part Context

This component belongs to the Microchip A42MX series, which bridges the gap between discrete logic and custom ASICs. The series is characterized by its high capacity relative to gate count and support for automotive temperature ranges. It serves as a flexible solution for designs requiring reprogrammability without the cost of full custom silicon.

Replacement Considerations

Direct substitutes within the same package include other A42MX24 variants such as A42MX24-PL84A or A42MX24-1PL84X79. Cross-family replacements like the A40MX series offer lower gate counts but similar functionality. Verify pin compatibility and electrical specifications before substitution.
