A42MX09-3VQ100I

Overview

The A42MX09-3VQ100I is a field-programmable gate array (FPGA) from the Microchip MX series, featuring approximately 14,000 system gates and 336 logic elements. It provides 83 I/O pins and operates within a supply voltage range of 4.5 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The component is housed in a VQFP-100 package with surface-mount installation. It supports an industrial temperature range from -40°C to +85°C. The device includes humidity sensitivity features and is classified under programmable logic ICs.

Feature Summary

• Configurable logic architecture utilizing flash-based non-volatile technology for instant-on functionality without external configuration memory.
• Supports mixed-voltage I/O interfaces compatible with both 3.3 V and 5 V signaling standards for flexible system integration.
• Integrated design environment compatibility allowing migration from legacy Actel FPGA designs using standard development tools.

Applications

• Industrial control systems requiring reliable operation across wide temperature ranges.
• Legacy system upgrades replacing older discrete logic or complex programmable logic devices (CPLDs).
• Embedded applications needing non-volatile configuration for immediate power-up readiness.

Procurement Notes

Verify the exact suffix 'VQ100' against official Microchip documentation, as standard listings typically specify 'VQG100' or 'PQG100'. Confirm moisture sensitivity level (MSL) requirements and reflow soldering profiles prior to assembly. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Selection Notes

Compare the A42MX09-3VQ100I with other MX series variants such as the A42MX16 for higher gate counts if design headroom is needed. Evaluate package options like PQFP-100 versus VQFP-100 based on PCB space constraints and thermal management requirements. Consider the A42MX09's lack of embedded memory when selecting between this model and families with integrated SRAM blocks.

Part Context

This component belongs to the Microchip A42MX09 family, which represents mid-range flash FPGAs derived from the legacy Actel portfolio. The MX series is characterized by its low-power consumption and robust radiation tolerance capabilities. It serves as a bridge between simple CPLDs and high-performance hard processor systems, offering deterministic timing for critical digital logic applications.

Replacement Considerations

Direct pin-compatible replacements include other A42MX09 variants with different speed grades or temperature ratings, such as A42MX09-VQG100I. For upgraded capacity, the A42MX16 series offers similar packaging but increased logic resources. Verify that any substitute maintains the same VQFP-100 footprint and electrical characteristics.
