A42MX24-1PLG84

Overview

The A42MX24-1PLG84 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. The component operates within an industrial temperature range of -40°C to +85°C and accepts a supply voltage between 4.5 V and 5.5 V.

Feature Summary

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

Applications

• Automotive electronic control units
• Industrial automation controllers
• High-reliability logic replacement circuits

Procurement Notes

Verify the specific suffix against official datasheets to confirm temperature grade and RoHS compliance status. Confirm package integrity and moisture sensitivity level prior to assembly. Ensure design tools support the legacy Actel/Microchip architecture for accurate synthesis and implementation.

Selection Notes

Select this model for designs requiring deterministic timing and mixed-voltage compatibility in a PLCC-84 footprint. Compare gate density and I/O counts against other A42MX variants to ensure optimal resource utilization. Verify that the 96 MHz performance meets system clock requirements.

Part Context

This component belongs to the A42MX family, designed as a high-capacity single-chip ASIC alternative. The series offers scalable logic resources ranging from 3,000 to 54,000 system gates. It integrates configurable dual-port SRAM and fast wide-decode circuitry for complex logic implementations.

Replacement Considerations

Direct substitutes include A42MX24-1PL84A and A42MX24-1PL84X79. These parts share identical gate counts and CLBs but may differ in temperature ratings or RoHS certification. Verify package pinout compatibility before substitution.
