A42MX09-1PQG100I

Overview

The A42MX09-1PQG100I is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip A42MX series, manufactured by Actel. It features 336 Configurable Logic Blocks (CLBs) and approximately 14,000 system gates. The device operates with a maximum clock frequency of 70.2 MHz and exhibits a CLB maximum combinational delay of 3.5 ns. It supports mixed-voltage operation at 3.3 V or 5.0 V for core and I/O supplies. The component is housed in a PQFP-100 plastic package with 83 user-programmable I/O pins. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration memory.
• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5.0V logic interfaces.
• Provides deterministic timing characteristics suitable for precise hardware design requirements.

Applications

• Industrial control systems requiring robust programmable logic.
• Automotive electronics applications compatible with mixed voltage standards.
• Military and aerospace embedded systems utilizing commercial temperature grade components.

Procurement Notes

Verify the specific speed grade suffix '1' against the official datasheet to confirm the 70.2 MHz performance rating. Ensure the PQFP-100 package matches the target PCB footprint. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for any specific humidity sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this model when a moderate gate count around 14,000 is sufficient for the design complexity. Choose the PQFP-100 package if surface mount technology compatibility with standard QFP footprints is required. Consider the 3.5 ns CLB delay for timing-critical paths within the 70.2 MHz operational limit. Evaluate the 83 available I/O pins against the interface requirements of the target application.

Part Context

This component belongs to the A42MX family of Flash FPGAs, originally developed by Actel and now produced by Microchip Technology. The series is characterized by its radiation tolerance options and non-volatile Flash technology. The A42MX09 variant specifically targets applications needing a balance between logic density and power efficiency in a compact form factor.

Replacement Considerations

Direct substitutes include other variants within the A42MX09 series such as A42MX09-PQG100I or A42MX09-FPQG100I, provided the speed grade and package match. Cross-series migration to higher-density parts like the A42MX16 may require significant schematic and layout redesigns due to pinout and resource differences.
