A42MX24-3TQG176I

Overview

The A42MX24-3TQG176I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, featuring 36,000 system gates and 912 Logic Elements. It provides 150 I/O pins within a TQFP-176 surface-mount package. The device operates at 3.3 V or 5 V with a supply voltage range of 4.75 V to 5.25 V. It supports an industrial temperature range of -40°C to +85°C. This component utilizes anti-fuse technology for non-volatile configuration.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation allowing independent selection of 3.3 V or 5.0 V for core and I/Os.
• Features deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

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

Procurement Notes

Verify the suffix 'I' confirms the industrial temperature grade (-40°C to +85°C), as standard commercial variants lack this rating. Confirm the specific package marking matches the TQFP-176 form factor. Check for recent Product Change Notifications regarding manufacturing site changes or material updates. Ensure design files are compatible with current Microchip programming tools.

Selection Notes

Select this model when 36K system gates and 150 I/Os are required in a 176-pin QFP package. Compare against the A42MX24-3TQG176 if industrial temperature ratings are not necessary. Consider the A42MX24-FPQG160 for different pin counts. Verify that the target application requires the specific speed grade indicated by the '3' suffix.

Part Context

This part belongs to the Microchip A42MX24 series, which offers 36,000 system gates. The series includes various packages such as PLCC, PQFP, and TQFP. The 'A42MX' designation indicates the 42MX family architecture using anti-fuse technology, distinct from the SRAM-based 40MX series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The A42MX24-3TQG176 is a pin-compatible variant without the industrial temperature rating. Cross-reference with the official Microchip compatibility matrix for verified alternatives.
