A42MX09-3PQG100I

Overview

The A42MX09-3PQG100I is a Flash-based Field Programmable Gate Array 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 5.5V, specifically operating at 4.5V minimum and 5.5V maximum for the 5V variant. It offers 83 user-programmable I/O pins and functions within an industrial temperature range of -40°C to +85°C. The FPGA utilizes non-volatile Flash technology, eliminating the need for external configuration memory.

Feature Summary

• Non-volatile Flash architecture enables instant-on functionality without external configuration devices.
• Supports mixed-voltage I/O interfaces compatible with both 3.3V and 5.0V logic levels.
• Provides deterministic timing through wide-decode circuitry and user-controllable delays.
• Allows 100% resource utilization and complete pin locking for secure design implementation.

Applications

• Single-chip ASIC replacement for low-to-medium complexity digital designs.
• Industrial control systems requiring robust performance in harsh environments.
• Automotive electronics applications utilizing mixed-voltage signaling.
• Military and aerospace systems requiring radiation-tolerant or high-reliability programmable logic.

Procurement Notes

Verify the specific suffix codes against the official Microchip datasheet to ensure correct voltage range and temperature grade. Confirm RoHS compliance status as manufacturing sites may vary. Check for recent Product Change Notifications regarding assembly site transfers or material updates. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate that the PQFP-100 footprint matches the target PCB design requirements.

Selection Notes

Select this component when a non-volatile FPGA with mixed-voltage I/O capability is required. Compare gate counts against the A42MX16 series if higher logic density is needed. Consider the PQFP-100 package constraints for board space. Verify that the 70.2 MHz maximum clock frequency meets the design timing requirements. Evaluate the 336 CLB count against alternative Actel or Microsemi families for cost optimization.

Part Context

This part belongs to the A42MX09 family, which represents mid-range capacity Flash FPGAs. It shares architectural similarities with the A42MX16 but offers fewer system gates. The device continues the legacy of Actel Flash FPGAs acquired by Microsemi and subsequently Microchip. It serves as a drop-in replacement for older PALs and GALs in complex logic applications.

Replacement Considerations

Direct functional substitutes include other parts within the A42MX09 family with different package options. The A42MX16 series offers higher density but may require software adaptation. Cross-reference with A42MX variants for different temperature grades or voltage specifications.
