A42MX24-1PQ160I

Overview

The A42MX24-1PQ160I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 160-pin PQFP package. It features 912 Logic Elements and approximately 36,000 system gates. The device supports mixed-voltage operation with core voltages of 3.3V or 5V and I/O voltages compatible with PCI standards. Operating parameters include a minimum supply voltage of 4.75V and a maximum of 5.25V for the 5V variant, or corresponding levels for 3.3V. The industrial temperature grade (-I suffix) ensures functionality between -40°C and +85°C. It provides up to 125 user-programmable I/O pins and includes configurable dual-port SRAM resources.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5V logic interfaces.
• Features deterministic timing with user-controllable constraints and pin locking capabilities.
• Includes configurable dual-port SRAM for efficient data buffering and FIFO applications.
• Provides high resource utilization with support for 100% pin locking.

Applications

• ASIC prototyping and low-volume production replacement
• Industrial control systems requiring mixed-voltage I/O
• Military and aerospace embedded logic processing

Procurement Notes

Verify the specific speed grade suffix and package type against the original design requirements. Confirm RoHS compliance status as manufacturing sites may vary. Check for End-of-Life notifications or Product Change Notifications regarding assembly site transfers. Ensure the industrial temperature range matches the operational environment specifications.

Selection Notes

Compare the A42MX24-1PQ160I with other members of the A42MX24 series based on I/O count and package availability. Consider the A42MX09 or A42MX16 variants if gate density requirements are lower. Evaluate the A40MX series for potential upgrades if higher performance or additional memory resources are needed. Verify that the 160-pin PQFP footprint is compatible with the existing PCB layout.

Part Context

This component belongs to the Microchip Actel MX FPGA family, designed as a single-chip ASIC alternative. The A42MX24 variant specifically offers 36,000 system gates, positioning it for medium-complexity logic designs. The '1' indicates a specific speed bin, while 'I' denotes the industrial temperature range. This series is known for non-volatile flash-based technology, eliminating the need for external configuration memory.

Replacement Considerations

Direct substitutes within the same package and speed grade should be prioritized. The A42MX24-1PQ160 without the 'I' suffix is available for commercial temperature ranges. Other packages in the A42MX24 family, such as PLCC or QFP-208, offer different I/O counts but require schematic modifications.
