A42MX24-3PQG208

Overview

The A42MX24-3PQG208 is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 912 Logic Elements and approximately 36,000 system gates within a 208-pin PQFP package. The device operates on a single 5V supply voltage with a range of 4.75V to 5.25V. It supports 150 I/O pins and functions within an industrial temperature range of -40°C to +125°C. This component utilizes non-volatile Flash technology for configuration retention.

Feature Summary

• Utilizes non-volatile Flash memory technology for instant-on configuration without external storage.
• Supports in-system programming and reconfiguration capabilities via standard interfaces.
• Provides high-density logic resources suitable for complex digital control applications.

Applications

• Industrial automation controllers requiring robust logic processing.
• Automotive electronic systems operating under harsh environmental conditions.
• Telecommunications infrastructure equipment needing reliable signal processing.

Procurement Notes

Verify the specific suffix '3' indicates the correct speed grade and temperature rating (-40°C to +125°C) required for your design. Confirm the PQFP-208 package dimensions match your PCB footprint. Check for recent Product Change Notifications or End-of-Life notices from Microchip, as availability may be limited due to discontinuation trends in this family.

Selection Notes

Select this part when a single 5V supply is preferred over dual-voltage options. Ensure the design requires approximately 912 LEs and fits within the 150 I/O constraint. Compare against the A42MX24-PQG208 if a commercial temperature range suffices, or consider the A42MX36 series if higher logic density is needed while maintaining similar package constraints.

Part Context

This component belongs to the Actel/Microchip MX family of Flash FPGAs, known for their radiation tolerance and security features. The A42MX24 variant represents a mid-range density option within the series, balancing resource count with power consumption. It serves as a successor to older EEPROM-based FPGA technologies, offering improved reliability and ease of use.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the discontinued status of many MX parts. Evaluate the A42MX36-PQG208 for increased logic capacity if the footprint allows. For modern equivalents, consider Microchip's PolarFire or Igloo2 families, though these require significant schematic and firmware redesign.
