A42MX24-1TQG176I

Overview

The A42MX24-1TQG176I is a field-programmable gate array from the Microchip MX family, housed in a 176-pin Thin Quad Flat Package. It provides approximately 36,000 system gates and 912 logic elements for digital design implementation. The device supports mixed-voltage operation with core and I/O options of 5.0V or 3.3V, adhering to PCI-compliant standards. It operates within a commercial temperature range of 0°C to +70°C and requires a supply voltage between 4.75V and 5.25V. The component includes IEEE 1149.1 JTAG boundary scan capabilities for testing and verification.

Feature Summary

• Supports up to 100% resource utilization and pin locking for deterministic timing control
• Enables single-chip ASIC replacement through synthesis-friendly architecture
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems utilizing mixed-voltage interfaces
• Military and aerospace designs compatible with MIL-STD-883 standards

Procurement Notes

Verify the specific suffix 'I' confirms industrial or commercial temperature rating alignment with project requirements. Confirm package integrity upon receipt as moisture sensitivity level indicates handling precautions are necessary. Cross-reference the latest datasheet revision to ensure compatibility with current design tools and programming software versions.

Selection Notes

Select this model when 36K system gates and 150 I/O pins are required in a TQFP-176 footprint. Ensure the design utilizes 3.3V or 5.0V logic levels compatible with the specified mixed-voltage operation. Verify that the application does not require embedded memory blocks, as this device relies on external configuration or internal SRAM bits only.

Part Context

This part belongs to the A42MX24 series within the broader MX FPGA portfolio. It shares architectural features with other variants like the A42MX24-3TQG176 but differs in speed grade and temperature rating. The series is designed to replace complex discrete logic or custom ASICs in cost-sensitive and low-to-medium volume production environments.

Replacement Considerations

Direct functional substitutes include other A42MX24 variants such as A42MX24-3TQG176, provided speed grades and temperature ranges match the design constraints. Pin-compatible replacements must maintain the 176-TQFP form factor and equivalent I/O counts.
