A42MX09-3TQG176

Overview

The A42MX09-3TQG176 is a field-programmable gate array from the Microchip MX series, featuring approximately 14,000 system gates and 336 logic elements. It provides 104 input/output pins and operates within a supply voltage range of 4.5 V to 5.5 V, with standard operation at 3.3 V or 5 V. The device is housed in a 176-pin TQFP package and supports surface-mount installation. It functions reliably across an industrial temperature range of -40°C to +85°C. This non-volatile FPGA utilizes flash-based technology for instant-on capability without external configuration memory.

Feature Summary

• Instant-on functionality enabled by embedded non-volatile flash memory architecture
• High-density programmable logic suitable for complex digital control applications
• Robust design supporting wide operating voltage and temperature ranges

Applications

• Industrial automation controllers requiring reliable startup sequences
• Telecommunications infrastructure signal processing
• Automotive electronic control units demanding high reliability
• Medical equipment logic interfacing

Procurement Notes

Verify the specific suffix '3' indicates the extended industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the 176-TQFP package dimensions match your PCB footprint requirements. Check for recent Product Change Notifications regarding manufacturing site or material updates. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification.

Selection Notes

Select this model when instant-on boot times are critical and external configuration EEPROMs cannot be used. Compare logic element counts against similar MX series parts if higher density is needed. Verify that the 104 I/O count meets interface requirements. Consider power consumption specifications relative to other FPGA families if thermal management is constrained.

Part Context

This component belongs to the Actel (now Microchip) MX family of flash FPGAs, known for combining SRAM flexibility with non-volatile storage. The A42MX09 variant represents a mid-range density option within this lineage. It serves as a successor to older PAL/GAL devices while offering reprogrammability. The part integrates on-chip configuration memory, simplifying board design compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct pin-to-pin replacements may include other A42MX09 variants with different packages or temperature grades. For upgraded capacity, consider A42MX24 or A42MX38 models if pin compatibility allows. Cross-family migration to PolarFire or IGLOO2 requires schematic and code adaptation despite functional similarities.
