A42MX16-2PLG84

Overview

The A42MX16-2PLG84 is a Field Programmable Gate Array (FPGA) from the MX Automotive Family, manufactured by Microchip Technology. It features 24,000 system gates and 608 Logic Elements (LEs). The device supports dual voltage operation with a minimum supply of 4.75 V and maximum of 5.25 V, compatible with 3.3 V and 5 V I/O standards. It includes up to 2.5 kbits of configurable dual-port SRAM and offers 72 user-programmable I/O pins. The component is housed in an 84-pin PLCC package and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Single-chip ASIC alternative capable of consolidating logic from multiple PALs, CPLDs, and FPGAs
• Deterministic, user-controllable timing with up to 100% resource utilization and pin fixing
• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix '2PLG84' against official Microchip documentation to confirm the exact speed grade and package variant. Confirm RoHS compliance status as some sources indicate non-compliance for older revisions. Check for End-of-Life (EOL) notifications or discontinuance alerts, as similar MX family parts have faced obsolescence. Ensure the procurement channel provides valid traceability for automotive-grade specifications if required.

Selection Notes

Select this model when a cost-effective single-chip solution is needed to replace complex discrete logic or smaller programmable devices. Consider the 24,000 gate capacity and 72 I/O count for moderate complexity designs. Verify that the 0°C to +70°C commercial temperature range meets the application requirements, as industrial or automotive grades may require different suffixes. Ensure the design utilizes the deterministic timing features for reliable integration.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between simple CPLDs and high-end FPGAs. The MX series is designed for applications requiring high performance at low power, leveraging flash-based technology for instant-on capabilities. The A42MX16 variant specifically targets mid-range logic density needs within the automotive and industrial sectors.

Replacement Considerations

Direct replacements are limited due to the discontinued status of many MX family parts. Evaluate newer Microchip PolarFire or IGLOO2 families for modern equivalents, though pinouts and capacities will differ significantly. Cross-reference with Actel legacy parts if maintaining original silicon is critical.
