A42MX16-PL84A

Overview

The A42MX16-PL84A is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 24,000 system gates and 608 logic elements, housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. The device supports dual voltage operation at 3V to 3.6V and 4.5V to 5.5V. It offers 72 I/O pins and operates within a temperature range of -55°C to 125°C. The component has a Moisture Sensitivity Level (MSL) of 3 and is classified as obsolete.

Feature Summary

• Non-volatile flash-based FPGA architecture providing instant-on functionality without external configuration memory.
• Supports both 3.3V and 5V supply voltages for flexible interface compatibility.
• High reliability design suitable for harsh environments with extended industrial temperature ratings.

Applications

• Industrial control systems requiring robust programmable logic.
• Automotive electronics applications demanding high thermal stability.
• Embedded systems utilizing low-power field-programmable gate arrays.

Procurement Notes

Verify the obsolete status of this part number before initiating procurement processes. Confirm that the 84-PLCC package dimensions align with existing PCB footprints. Check for RoHS compliance variations between manufacturing batches. Ensure that the MSL 3 rating is accounted for in storage and handling procedures to prevent moisture damage during assembly.

Selection Notes

Select this model when a non-volatile FPGA solution with 24K system gates is required in a PLCC-84 package. Compare against the A42MX24-PL84A if higher gate counts are needed. Consider alternative packages such as TQFP or PQFP if surface-mount lead-free options are preferred over the legacy PLCC form factor.

Part Context

This component belongs to the Actel MX family of flash FPGAs, which were acquired by Microchip Technology. The MX series is characterized by its non-volatile flash technology, eliminating the need for external configuration PROMs. This specific part represents a mid-range density option within the legacy portfolio, designed for cost-sensitive and space-constrained embedded applications.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the obsolete status. Evaluate the A42MX24-PL84A for increased capacity in the same package. For modern alternatives, consider Microchip's PolarFire or IGLOO2 families, though these require schematic and layout redesigns.
