A42MX16-2PL84I

Overview

The A42MX16-2PL84I is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 24,000 system gates and operates with a supply voltage range of 3V to 3.6V or 4.5V to 5.5V. The device utilizes an 84-pin PLCC package with J-Lead configuration. It supports surface mount installation and functions within a temperature range of -40°C to +85°C. Key specifications include 72 I/O pins, 608 Logic Elements, and up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

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

Applications

• Automotive logic consolidation
• High-speed controllers
• Peripheral bus interfaces

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for some variants in this series. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Check for official discontinuation notices or product change notifications prior to finalizing procurement plans.

Selection Notes

Select this model for designs requiring deterministic timing and mixed-voltage operation between 3.3V and 5.0V cores. Ensure the 84-pin PLCC footprint matches the PCB layout. Verify that the 24,000 gate capacity meets the specific logic density requirements compared to other members of the A42MX family.

Part Context

This component belongs to the Microchip MX FPGA family, originally developed by Actel and acquired by Microsemi before merging into Microchip Technology. The series is designed to replace multiple PALs, CPLDs, and FPGAs with a single high-performance chip, offering cost-effective solutions for complex logic applications.

Replacement Considerations

Compatible substitutes within the same family include A42MX16-1PL84M and A42MX16-2PL84A. Verify package compatibility and temperature grade differences when selecting alternatives.
