A42MX16-2PL84

Overview

The A42MX16-2PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It features 24,000 system gates and supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. The device provides 72 I/O pins and utilizes an 84-pin PLCC package. It operates within a temperature range of -40°C to +125°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM and support for IEEE Standard 1149.1 JTAG boundary scan testing.

Feature Summary

• Single-chip ASIC alternative designed for automotive applications
• Synthesis-friendly architecture supporting 100% resource utilization and pin fixing
• Deterministic, user-controllable timing with unique in-system diagnostic capability

Applications

• Automotive electronic control units
• Industrial motor control systems
• Aerospace avionics logic replacement

Procurement Notes

Verify RoHS compliance status as specific variants may differ. Confirm package integrity upon receipt due to moisture sensitivity level 3 requirements. Check for obsolescence notices or PCN updates regarding manufacturing changes. Ensure ESD protection protocols are followed during handling and storage to maintain device reliability.

Selection Notes

Select this model when 24,000 system gates and 72 I/Os are required in an 84-pin PLCC form factor. Choose the -2 speed grade for specific timing constraints. Verify voltage supply compatibility with both 3.3V and 5V domains. Consider thermal management capabilities given the extended industrial temperature range up to 125°C.

Part Context

Part of the A42MX series FPGAs targeting high-reliability markets. Shares architectural similarities with A40MX and A42MX families but offers enhanced gate density. Designed to replace complex discrete logic or custom ASICs in safety-critical environments. Compatible with Actel Libero design software for configuration and programming.

Replacement Considerations

Direct substitutes include other A42MX series devices with compatible pinouts such as A42MX16-1PL84 or A42MX16-2PL84I if temperature grades differ. Cross-reference with A40MX series for lower gate count alternatives. Verify functional equivalence before substitution in certified automotive or aerospace designs.
