A42MX09-1PQG100

Overview

The A42MX09-1PQG100 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 336 Logic Elements and approximately 14,000 system gates within a PQFP-100 package. The device supports mixed-voltage operation with core and I/O supplies ranging from 3.3V to 5.0V, specifically operating between 4.5V and 5.5V for standard configurations. It offers 83 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. The FPGA utilizes anti-fuse technology for non-volatile configuration.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V logic levels.
• Provides deterministic timing through user-controllable delay elements and pin locking capabilities.
• Features high resource utilization efficiency with up to 100% pin locking for precise signal routing.

Applications

• Single-chip ASIC replacement in embedded control systems
• Industrial automation and motor control interfaces
• Military and aerospace avionics subsystems

Procurement Notes

Verify the specific suffix '1' against official Microchip documentation to confirm speed grade and voltage tolerances. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure the PQFP-100 footprint matches the target PCB design constraints. Check current production status as legacy Actel products may have limited availability or obsolescence notices.

Selection Notes

Select this component when a small form factor FPGA with guaranteed timing is required. Compare against the A42MX09-PQG100I if commercial temperature range suffices. Consider higher gate counts like the A42MX16 if additional logic resources are needed. Verify that the 83 I/O count meets interface requirements without external multiplexing.

Part Context

This part belongs to the A42MX09 family, originally developed by Actel before its acquisition by Microsemi and subsequently Microchip. The MX series is distinguished by its flash-based or anti-fuse architecture depending on the specific generation, offering radiation tolerance and instant-on capability compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct substitutes include other variants within the A42MX09 family such as A42MX09-PQG100I for commercial temperature grades. Cross-family replacements from Xilinx or Lattice require significant redesign due to architectural differences in logic blocks and I/O standards.
