A42MX16-TQG176M

Overview

The A42MX16-TQG176M is a non-volatile Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series. It features 24,000 system gates and 608 Logic Elements within a 176-pin TQFP package. The device supports dual voltage operation with supply ranges of 3V to 3.6V and 4.5V to 5.5V. It provides 140 I/O pins and operates across an industrial temperature range of -40°C to 125°C. The component utilizes CMOS technology and includes built-in security features for intellectual property protection.

Feature Summary

• Non-volatile Flash architecture enables instant-on functionality without external configuration memory.
• Integrated security features protect design intellectual property against unauthorized access.
• Supports in-system programming and reconfiguration capabilities.

Applications

• Industrial control systems requiring reliable logic processing
• Automotive electronics applications
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm it denotes the military or extended temperature grade variant, as standard commercial variants typically use different suffixes. Ensure the datasheet confirms the 176-TQFP package dimensions and pinout compatibility before finalizing procurement orders.

Selection Notes

Select this model when a moderate gate count of 24K is required alongside high-temperature resilience up to 125°C. Compare against the A42MX24 series if higher logic density is needed. Verify that the 176-pin footprint matches the target PCB layout constraints and that the I/O voltage levels align with the system requirements.

Part Context

This part belongs to the Microchip MX family of Flash FPGAs, which succeeded the Actel SmartFusion predecessor line. The MX series is characterized by its low power consumption and robust security features, making it suitable for embedded applications where code protection and rapid boot times are critical design factors.

Replacement Considerations

Direct functional equivalents include the A42MX16-PQG100A for smaller packages or the A42MX24-TQG176A for increased logic density. Verify pin-to-pin compatibility and software toolchain support when considering these alternatives.
