A42MX16-3PL84

Overview

The A42MX16-3PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 24,000 system gates and 608 Logic Elements (LEs). The device supports mixed-voltage operation with supply voltages ranging from 3V to 3.6V or 4.5V to 5.5V. It utilizes an 84-pin Plastic Leaded Chip Carrier (PLCC) package. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Supports mixed-voltage core and I/O operations compatible with 3.3V and 5V standards.
• Provides deterministic, user-controllable timing suitable for precise design methodologies.
• Enables up to 100% resource utilization and pin locking for efficient integration.

Applications

• Automotive electronic systems requiring robust programmable logic.
• Single-chip ASIC replacement designs in industrial control.
• Mixed-signal interface circuits utilizing multi-voltage compatibility.

Procurement Notes

Verify RoHS compliance status through official datasheets, as variations exist across the MX series. Confirm the specific suffix indicates the correct temperature grade and package variant. Check for Product Change Notifications regarding assembly sites or material updates. Ensure the ordering code matches the required voltage and speed grades.

Selection Notes

Select this model for designs requiring 24,000 system gates in an 84-pin PLCC footprint. Verify that the 83 available I/O pins meet interface requirements. Ensure the operating environment falls within the specified -40°C to +125°C range. Compare against other MX series variants if higher gate counts or different packages are needed.

Part Context

This component belongs to the Actel MX family, now manufactured by Microchip Technology. The MX series is characterized by non-volatile Flash technology, allowing instant-on functionality without external configuration memory. This architecture simplifies board design by eliminating configuration chips typically required by volatile FPGAs.

Replacement Considerations

Direct replacements include other A42MX16 variants with different packages such as A42MX16-PQG100A or A42MX16-VQG100A. Cross-reference speed grades and voltage specifications when substituting. Verify package compatibility for PCB re-design if changing from PLCC to QFP or VQFP formats.
