A42MX24-1PL84

Overview

The A42MX24-1PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 36,000 system gates and 912 Configurable Logic Blocks (CLBs). The device supports a maximum clock frequency of 96 MHz with a CLB combination delay of 2.1 ns. It utilizes a Plastic Leaded Chip Carrier (PLCC) package with 84 terminals, providing 176 user-programmable I/O pins. Operating parameters include a supply voltage range of 4.5 V to 5.5 V and an operating temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Deterministic, user-controllable timing
• Supports up to 100% resource utilization and pin fixing

Applications

• Automotive electronic control units
• Industrial logic replacement
• Custom interface bridging

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm RoHS compliance status as specific suffixes may vary. Check for End-of-Life notifications or Product Change Notices regarding availability. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this model for designs requiring deterministic timing and high gate density in an 84-pin PLCC package. Compare against other A42MX24 variants based on required I/O count and temperature grade. Verify that the 96 MHz performance meets system clock requirements. Consider pin compatibility if migrating from legacy ASICs.

Part Context

This component belongs to the Actel/Microchip MX family of flash-based FPGAs. These devices are designed to replace complex discrete logic and custom ASICs. The family offers non-volatile configuration memory, eliminating the need for external configuration devices common in SRAM-based FPGAs.

Replacement Considerations

Direct substitutes include other A42MX24 variants such as A42MX24-PL84A or A42MX24-PL84I, depending on temperature and speed grades. Cross-family migration to Microsemi RTG4 or PolarFire may be necessary for long-term supply assurance.
