A42MX24-3PQ208I

Overview

The A42MX24-3PQ208I is a Field Programmable Gate Array (FPGA) from the Microchip Technology A42MX24 series. It features 912 Logic Elements and supports up to 176 user-programmable I/O pins within a PQFP-208 surface-mount package. The device operates on a single 5V supply voltage, with a specified range of 4.75 V to 5.25 V. It is rated for an industrial temperature range of -40°C to +85°C. This component serves as a high-capacity single-chip ASIC alternative, integrating fast wide-decode circuitry and deterministic timing capabilities.

Feature Summary

• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Provides deterministic, user-controllable timing characteristics
• Enables up to 100% resource utilization and pin locking

Applications

• High-speed controllers
• Address decoding systems
• Peripheral bus interfaces

Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as lead times may vary significantly for this specific part number. Confirm that the procurement channel provides valid traceability documentation. Ensure compliance with RoHS directives and check for any active Product Change Notifications (PCNs) related to assembly sites or material composition updates prior to finalizing orders.

Selection Notes

Select this model when a 5V logic family FPGA is required for designs needing approximately 912 logic elements. The PQFP-208 package is suitable for applications requiring a high density of general-purpose I/Os. Verify that the system power supply strictly adheres to the 4.75 V to 5.25 V operating range to ensure reliable performance across the specified industrial temperature spectrum.

Part Context

This component belongs to the Actel MX family of FPGAs, originally developed by Actel Corporation and subsequently acquired by Microsemi, which was later acquired by Microchip Technology. The A42MX24 designation indicates a device with approximately 36,000 system gates. These devices are designed to replace complex discrete logic solutions, offering reprogrammability and consolidation of multiple PALs, CPLDs, or smaller FPGAs onto a single chip.

Replacement Considerations

Consult official Microchip cross-reference tools for verified compatible replacements. Consider variants within the A42MX24 series that offer different package types or speed grades if the PQFP-208 form factor is unavailable. Verify functional equivalence regarding I/O counts and logic capacity before substituting.
