A42MX24-1TQ176I

Overview

The A42MX24-1TQ176I is a Field Programmable Gate Array (FPGA) from the Microsemi MX series, housed in a 176-pin Thin Quad Flat Package (TQFP). It provides 36,000 system gates and supports mixed-voltage operation with supply ranges of 3V to 3.6V and 4.5V to 5.5V. The device features 150 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. It utilizes SRAM-based technology for non-volatile configuration storage.

Feature Summary

• Supports mixed-voltage core and I/O operations compatible with 3.3V and 5.0V standards
• Provides deterministic, user-controllable timing for precise signal synchronization
• Enables up to 100% resource utilization with full pin locking capabilities

Applications

• Automotive electronic control units requiring robust logic processing
• Industrial automation systems needing reliable programmable logic
• Military applications utilizing commercial temperature grade components

Procurement Notes

Verify component authenticity through authorized channels due to obsolescence status. Confirm specific suffix variations against official datasheets as package or temperature grades may differ. Check for RoHS compliance details as older revisions may not meet current environmental standards. Validate moisture sensitivity levels prior to surface mount assembly processes.

Selection Notes

Select this model when 36,000 system gates are required in a 176-pin TQFP form factor. Ensure design requirements align with the specified 3V to 3.6V and 4.5V to 5.5V voltage domains. Consider the -40°C to +85°C operating range for industrial environments. Verify that the 150 available I/O pins meet interface density needs.
