A42MX09-2VQG100

Overview

The A42MX09-2VQG100 is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microchip Technology under the Actel brand. It features 336 Logic Elements and approximately 14,000 system gates within a 100-pin VQFP package. The device supports mixed-voltage operation with core and I/O supplies of 3.3V or 5V, operating within voltage ranges of 4.5V to 5.5V. It offers 83 user-programmable I/O pins and functions at a maximum clock frequency of 70.2 MHz with a CLB combination delay of 3.5 ns. The component is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative capability with high capacity logic resources
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O supplies
• Deterministic, user-controllable timing with up to 100% resource utilization
• HiRel features including availability in commercial, industrial, automotive, and military temperature grades

Applications

• Industrial control systems requiring deterministic timing
• Automotive electronics applications
• Military and aerospace embedded systems
• General-purpose programmable logic replacement for ASICs

Procurement Notes

Verify the specific suffix '2' indicates the correct speed grade and industrial temperature rating (-40°C to +85°C). Confirm the VQFP100 package type matches the design footprint. Ensure compliance with RoHS directives and check for any export control classifications such as ECCN 3A991D. Validate that the 3.3V/5V mixed-voltage requirements align with the target system power rails.

Selection Notes

Select this model when 336 CLBs are sufficient for the design complexity. Choose the VQFP100 package if surface-mount space allows for a 14x14mm footprint. Consider the 70.2 MHz performance limit for clock domain requirements. Verify that the 83 available I/O pins meet the interface count needs, noting that not all 100 pins are usable as general I/O.

Part Context

This component belongs to the A42MX09 family, which provides SRAM-based FPGA technology. The MX series is known for low power consumption and non-volatile configuration capabilities when used with external flash. This specific part represents the mid-range density option within the A42MX09 lineup, offering a balance between gate count and pin availability in a compact QFP form factor.

Replacement Considerations

Direct substitutes include other variants in the A42MX09 series such as A42MX09-VQG100I or A42MX09-FVQG100, depending on required temperature grade and speed bin. Cross-family migration to A42MX16 may be necessary if additional logic resources are needed, though pin compatibility must be verified.
