A42MX16-1PL84

Overview

The A42MX16-1PL84 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 supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. The device provides 72 I/Os within an 84-LCC (J-Lead) package. It operates across a temperature range of -55°C to 125°C and includes up to 2 kbits of configurable dual-port SRAM.

Feature Summary

• Supports deterministic, user-controllable timing with unique in-system diagnostic capability via Silicon Explorer II.
• Features fast wide-decode circuitry and synthesis-friendly architecture that supports ASIC design methodologies.
• Enables up to 100% resource utilization and 100% pin fixing for ease of integration.

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Systems requiring deterministic timing and user-controllable delays
• Designs utilizing ASIC design methodologies with high resource utilization

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for some variants in this series. Confirm lead times and obsolescence notices directly with Microchip Technology or authorized distributors, as availability may vary significantly between industrial and automotive grades.

Selection Notes

Select the A42MX16-1PL84 when an 84-pin LCC package is required alongside a wide operating temperature range extending to -55°C. Ensure the design utilizes the 3V or 5V supply rails compatible with this specific speed grade and gate count configuration.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between discrete logic and ASICs. The A42MX16 variant specifically offers 24,000 system gates, positioning it for medium-complexity logic designs compared to the smaller A40MX or larger A54SX devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with newer Actel/Microchip FPGA families if replacement is necessary due to end-of-life status.
