A42MX09-2TQG176I

Overview

The A42MX09-2TQG176I is a field-programmable gate array (FPGA) from the Microchip MX series, designed for low-power applications. It features 24,000 system gates and 608 logic elements within a 176-pin TQFP package. The device supports dual voltage operation with a minimum supply of 4.5V to 4.75V and a maximum of 5.25V to 5.5V. It operates reliably across an industrial temperature range from -40°C to +85°C. Key specifications include 104 input/output pins and surface-mount installation style.

Feature Summary

• Non-volatile flash-based architecture enabling instant-on functionality without external configuration memory.
• Supports in-system programming and reconfiguration via standard JTAG interfaces.
• Integrated security features including bitstream encryption and authentication.

Applications

• Industrial control systems requiring deterministic timing.
• Automotive electronics modules operating in harsh environments.
• Telecommunications infrastructure interface circuits.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the '2' speed grade matches design timing requirements. Ensure the 176-TQFP package dimensions align with PCB footprint constraints. Check RoHS compliance status against current manufacturing notices.

Selection Notes

Compare gate count and I/O availability against higher-density models like the A42MX16 if future scalability is needed. Evaluate power consumption differences between 3.3V and 5V operation modes. Consider package thermal performance for enclosed industrial enclosures. Verify compatibility with existing FPGA toolchains and programming cables.

Part Context

This component belongs to the Microchip A42MX family, which utilizes Actel's proven flash FPGA technology. The series is characterized by low static power consumption and high reliability. It serves as a drop-in replacement for older EPROM-based PLDs in legacy designs while offering greater flexibility.

Replacement Considerations

Direct pin-compatible alternatives within the same package may include other variants from the A42MX series with different speed grades or temperature ranges. Cross-reference with A42MX09-1TQG176I for commercial grade options if environmental constraints allow.
