A42MX09-3VQG100

Overview

The A42MX09-3VQG100 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Actel. It features 336 Logic Elements and approximately 14,000 system gates. The device operates with a core voltage of 3.3 V and supports I/O voltages of 3.3 V or 5.0 V. It utilizes a 100-pin VQFP package. Key electrical parameters include a maximum clock frequency of 70.2 MHz and a CLB-max combinational delay of 3.5 ns. The component is RoHS compliant and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Supports mixed-voltage operation for both core and I/O supplies, enabling compatibility with 3.3 V and 5.0 V systems.
• Provides deterministic, user-controllable timing to ensure predictable signal propagation within the design.
• Allows 100% resource utilization and full pin locking capabilities for precise hardware configuration.

Applications

• Single-chip ASIC replacement for legacy logic designs
• Mixed-signal interface bridging between different voltage domains
• Prototyping for digital signal processing applications

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm it denotes the commercial temperature range variant. Ensure the ordering part number matches the exact package type and speed grade required for your application. Cross-reference the manufacturer's latest Product Change Notifications (PCNs) to confirm assembly site and material composition stability before finalizing procurement orders.

Selection Notes

Select this model when a moderate gate count around 14,000 system gates is sufficient for the target logic complexity. Consider the VQFP-100 package dimensions if surface-mount space is constrained. Verify that the 70.2 MHz maximum operating frequency meets the timing requirements of the intended synchronous circuits. Confirm that the mixed-voltage I/O capability aligns with the connected peripheral devices.

Part Context

This component belongs to the A42MX09 family, which represents mid-range capacity SRAM-based FPGAs. The MX series is characterized by its high-density logic blocks and embedded memory options, designed to replace complex discrete logic or small ASICs. It serves as a bridge between low-end CPLDs and higher-end FPGA families in terms of resource availability and performance.

Replacement Considerations

Direct functional substitutes within the same density class may include other variants from the A42MX09 series with different package footprints, such as PQFP or PLCC versions. For higher density needs, the A42MX16 series offers increased logic resources while maintaining similar architectural features.
