A42MX24-TQG176A

Overview

The A42MX24-TQG176A is a Microchip Technology FPGA from the MX series, featuring 36K system gates and 912 logic elements. It provides 150 I/Os in a TQFP-176 package. Operating voltage ranges from 4.75V to 5.25V, with a commercial temperature range of 0°C to +70°C. The device supports 3.3V and 5V operation and includes humidity sensitivity features.

Feature Summary

• Non-volatile flash-based architecture for instant-on functionality
• High-density programmable logic with 36K system gates
• Supports multiple I/O standards via flexible pin configuration

Applications

• Industrial control systems requiring non-volatile reconfiguration
• Automotive infotainment and instrumentation interfaces
• Telecommunications baseband processing modules

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Check for EOL status notifications as many MX series parts face discontinuation. Confirm moisture sensitivity level handling requirements during storage and assembly to prevent damage.

Selection Notes

Compare against A42MX24 variants with different packages like PQFP or PLCC if pin count differs. Ensure voltage compatibility between 3.3V and 5V domains. Consider thermal performance within the specified operating range for your enclosure design.

Part Context

Part of the Actel/Microchip MX family, bridging CPLD and FPGA capabilities. Designed for low-power, high-reliability applications where code security and instant power-up are critical. Replaces older EPROM-based Actel devices.

Replacement Considerations

Direct substitutes include other A42MX24 package variants such as A42MX24-PQ208A or A42MX24-PLG84M if pinout compatibility allows. Verify gate density matches if upgrading from lower-density MX parts.
