A42MX09-1TQG176

Overview

The A42MX09-1TQG176 is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microchip Technology. It features approximately 14,000 system gates and 336 Logic Elements (LEs). The device provides 101 to 104 I/O pins and operates within a supply voltage range of 4.75 V to 5.25 V for the 5V core, or 3.0 V to 3.6 V for the 3.3V core. It supports an industrial temperature range of -40°C to +85°C. The component is housed in a 176-pin Thin Quad Flatpack (TQFP) package with dimensions of 24x24 mm.

Feature Summary

• Non-volatile Flash-based architecture enabling instant-on functionality without external configuration memory.
• Supports both 3.3V and 5V power domains for flexible interface compatibility.
• Includes built-in debug capabilities via the Actel Debug Module for real-time signal monitoring.

Applications

• Industrial control systems requiring reliable logic processing.
• Automotive electronics applications operating in harsh environments.
• Telecommunications infrastructure equipment.
• Medical device signal processing circuits.

Procurement Notes

Verify the specific suffix '1TQG176' against official Microchip documentation to confirm the exact speed grade and temperature rating. Ensure compliance with RoHS directives if required for your assembly process. Check for any Product Change Notifications (PCNs) related to packaging or material updates before finalizing procurement plans.

Selection Notes

Select this model when a moderate gate count of 14K is sufficient for complex logic designs. Consider the TQFP-176 package for surface-mount assembly constraints. Verify that the 101/104 I/O count meets all interface requirements. Compare performance metrics against higher-density MX variants if additional logic resources are anticipated for future revisions.

Part Context

This component belongs to the A42MX09 family within the broader MX FPGA portfolio. It shares architectural similarities with other devices in the series but offers a specific balance of logic density and I/O availability. The part is distinct from the A42MX24 series, which provides higher gate counts. Understanding the family hierarchy aids in selecting compatible development tools and software configurations.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the A42MX09 family, such as different speed grades or packages. Cross-referencing the datasheet for equivalent logic capacity and I/O mapping is essential. No direct substitute part numbers are publicly confirmed for this specific suffix combination.
