A42MX16-PL84

Overview

The A42MX16-PL84 is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive Family. It provides 24,000 system gates and supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. The device features 72 I/Os within an 84-pin PLCC package. It includes up to 2 kbits of configurable dual-port SRAM and utilizes fast wide-decode circuitry for synthesis-friendly architecture.

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
• ASIC prototyping and replacement
• Industrial logic control systems

Procurement Notes

Verify RoHS compliance status as specific suffixes vary; some variants are non-compliant. Confirm moisture sensitivity level and lead-free availability through official Microchip documentation or authorized distributors prior to procurement.

Selection Notes

Select based on required gate count and I/O density. Ensure voltage supply matches the 3V or 5V variant requirements. Verify package compatibility with PCB footprint and check temperature range specifications against environmental operating conditions.

Part Context

Part of the MX Automotive Family FPGAs, offering 3,000 to 54,000 system gates. Designed as a low-power, high-reliability solution for replacing custom ASICs in harsh environments with deterministic timing characteristics.

Replacement Considerations

Check for direct pin-compatible upgrades within the A42MX series such as A42MX24. Verify functional equivalence if substituting with other Actel/Microchip FPGA families.
