A42MX09-1VQG100

Overview

The A42MX09-1VQG100 is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX series, originally developed by Actel. It features 336 Configurable Logic Blocks (CLBs) and approximately 14,000 system gates, housed in a 100-pin VQFP package with 83 I/Os. The device supports dual voltage operation at 3.3V and 5V, with a minimum supply of 4.5V and maximum of 5.5V for standard logic levels. It operates within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum clock frequency of 70.2 MHz and a CLB combinational delay of 3.5 ns.

Feature Summary

• Supports mixed 3.3V and 5V I/O configurations for flexible interface integration
• Utilizes flash-based non-volatile technology for instant-on functionality without external configuration memory
• Provides high-density logic resources suitable for complex digital control applications

Applications

• Industrial automation controllers requiring robust logic processing
• Telecommunications infrastructure equipment interfaces
• Automotive electronic control units (ECUs)
• Test and measurement instrumentation logic cores

Procurement Notes

Verify the specific suffix '1' against official Microchip documentation to confirm it denotes the industrial temperature grade (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 100-VQFP package. Confirm RoHS compliance status through current datasheets as manufacturing sites may change. Check for any recent Product Change Notifications (PCNs) regarding assembly or material updates.

Selection Notes

Select this component when a balance of moderate logic density and high-speed performance is required. Compare against the A42MX16 series if higher gate counts are needed. Verify that the 70.2 MHz operating speed meets timing constraints. Consider the VQFP-100 package size relative to board space limitations. Ensure power supply rails support both 3.3V and 5V requirements if mixed signaling is used.

Part Context

This part belongs to the A42MX09 family, which represents mid-range capacity FPGAs in the Actel/Microchip portfolio. It shares architectural similarities with the A42MX16 but offers fewer logic elements. The series is known for its radiation tolerance options and low power consumption compared to SRAM-based FPGAs. It serves as a drop-in replacement for older CPLDs in many legacy designs.

Replacement Considerations

Direct pin-compatible substitutes within the same family include other A42MX09 variants with different temperature grades or packages. For higher capacity needs, the A42MX16 series offers similar interfaces but increased logic resources. Cross-family migration to PolarFire or IGloo2 requires significant design re-verification due to architectural differences.
