A42MX24-TQ176M

Overview

The A42MX24-TQ176M 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 a temperature range of -40°C to 85°C. It includes up to 2.5 kbits of configurable dual-port SRAM and supports JTAG boundary scan testing.

Feature Summary

• Supports mixed-voltage core and I/O operations for compatibility with 3.3V and 5.0V logic levels.
• Features deterministic, user-controllable timing with fast wide-decode circuitry.
• Includes unique in-system diagnostic capability via Silicon Explorer II technology.

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems utilizing mixed-voltage interfaces
• Military and aerospace environments requiring high-reliability programmable logic

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade variant or specific packaging configuration, as standard commercial listings may not explicitly detail this suffix's functional impact. Confirm RoHS compliance status, as many MX family devices are non-compliant. Check for End-of-Life notifications, as the A42MX24 series has been subject to discontinuation notices.

Selection Notes

Select this component when a high-density FPGA with 36,000 system gates is required in a TQFP-176 package. Ensure the design accommodates the specified voltage ranges of 3V–3.6V and 4.5V–5.5V. Verify that the 150 available I/O pins meet the interface requirements. Consider the -40°C to 85°C operating temperature range for environmental suitability.

Part Context

The A42MX24-TQ176M belongs to the Microsemi 42MX FPGA family, which offers capacities ranging from 3,000 to 54,000 system gates. This family is designed as a single-chip ASIC alternative, featuring up to 2.5 kbits of configurable dual-port SRAM and support for PCI-compliant I/Os. The TQFP-176 package is common across several variants in this series, including commercial and industrial temperature grades.

Replacement Considerations

Publicly confirmed substitute part numbers for the specific A42MX24-TQ176M suffix are not available in the provided data. Related family members such as A42MX24-TQ176I or A42MX24-3TQG176 share similar gate counts but differ in package type or speed grade.
