A42MX24-TQ176

Overview

The A42MX24-TQ176 is a Field Programmable Gate Array (FPGA) from the Microsemi MX series, designed as a single-chip ASIC alternative. It features 36,000 system gates and supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. The device includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. It offers up to 202 user-programmable I/O pins with a maximum clock-to-out delay of 5.6 ns and performance up to 250 MHz. The component utilizes a 176-pin TQFP package.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 3.3V or 5.0V levels
• Includes up to 2.5 kbits of configurable dual-port SRAM for memory applications
• Features fast wide-decode circuitry for efficient address decoding
• Provides deterministic, user-controllable timing for precise design implementation

Applications

• Automotive embedded logic control systems
• Industrial automation interface modules
• Military avionics signal processing units

Procurement Notes

Verify the specific suffix requirements for the requested model against official datasheets, as variations exist in temperature grades and package types. Confirm RoHS compliance status, as some MX series variants are non-compliant. Check for End-of-Life notifications or Product Change Notices regarding availability and manufacturing continuity before finalizing procurement plans.

Selection Notes

Select this component when a high-density FPGA solution with mixed-voltage I/O capabilities is required for automotive or industrial environments. Ensure the design accommodates the 176-pin TQFP footprint and thermal constraints. Verify that the 36,000 gate capacity and SRAM resources meet the specific logic and data storage demands of the target application architecture.

Part Context

This part belongs to the Microsemi MX family of FPGAs, which serves as a bridge between discrete logic and custom ASICs. The family emphasizes low power consumption and ease of integration for designers familiar with standard synthesis flows. These devices are noted for their robustness in harsh environments, supporting both commercial and military specifications depending on the specific grade suffix.

Replacement Considerations

Direct replacements within the same package and pinout include other members of the A42MX24 series such as A42MX24-1TQ176I or A42MX24-3TQ176B, provided temperature ranges match. Cross-family migration to newer Microsemi SmartFusion or IGLOO2 devices requires significant schematic and firmware redesign due to architectural differences.
