A42MX09-3TQG176I

Overview

The A42MX09-3TQG176I is a field-programmable gate array from the Microchip A42MX09 series, featuring 14,000 system gates and 336 logic elements. It provides 104 input/output pins within a 176-pin TQFP package. The device operates on supply voltages of 3.3 V or 5 V, with absolute maximum ratings between 4.5 V and 5.5 V. It supports an industrial temperature range from -40°C to +85°C. The component utilizes flash-based non-volatile memory technology for configuration retention.

Feature Summary

• Flash-based architecture enabling in-system reprogrammability without external configuration memory
• Supports both 3.3 V and 5 V power supply domains for flexible interface compatibility
• Industrial-grade thermal rating suitable for demanding operational environments

Applications

• Industrial control systems requiring reliable programmable logic
• Automotive electronics operating under extended temperature conditions
• Communication infrastructure equipment needing flexible I/O configurations

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against official datasheets. Confirm the '3' speed grade matches design timing requirements. Check current production status as older A42MX variants may face discontinuation notices. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this variant when 104 I/O lines and 14K gates are required in a TQFP-176 form factor. Compare against PQFP-100 options if pin count constraints allow smaller footprints. Verify voltage domain compatibility with target peripherals before finalizing the 3.3 V or 5 V operation mode. Consider lead times associated with legacy Actel product lines.

Part Context

This component belongs to the A42MX family, originally developed by Actel before acquisition by Microchip Technology. The series represents mid-density flash FPGAs designed for cost-sensitive applications requiring low static power consumption. It serves as a successor to earlier RTAX and ProASIC families in specific market segments.

Replacement Considerations

Publicly confirmed substitutes include other members of the A42MX09 series such as A42MX09-PQG100I for reduced pin counts, or A42MX24 series variants for higher density needs. Cross-reference package dimensions when substituting between TQFP and PQFP formats.
