A42MX09-3VQG100I

Overview

The A42MX09-3VQG100I is a Field Programmable Gate Array from the MX series, manufactured by Microchip Technology. It features 684 Logic Elements and 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates. The device supports mixed-voltage operation with core voltages of 3.3 V or 5 V and I/O supplies up to 5.5 V. It operates within a temperature range of -40 °C to +85 °C. The maximum clock frequency is 161 MHz, with a CLB maximum combinational delay of 1.6 ns. It is housed in a 100-pin VQFP package.

Feature Summary

• Supports mixed-voltage operation for both core and I/O supplies, enabling compatibility with 3.3 V and 5 V systems.
• Provides deterministic, user-controllable timing through 100% pin locking capabilities.
• Offers high resource utilization allowing for single-chip ASIC alternative designs.

Applications

• Industrial control systems requiring mixed-voltage interfaces
• Automotive electronics operating in industrial temperature ranges
• Military applications utilizing commercial plastic packages

Procurement Notes

Verify the specific speed grade suffix against official datasheets, as variations exist within the A42MX09 family. Confirm RoHS compliance status, as some variants may not meet current standards. Check for moisture sensitivity level requirements during storage and handling. Ensure the VQFP-100 package availability aligns with manufacturing lead times. Validate that the selected variant meets the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this model when 14,000 system gates and 684 logic elements are sufficient for the design complexity. Choose the VQFP-100 package if surface-mount technology with a quad flat package form factor is required. Consider the 161 MHz performance limit for timing-critical paths. Verify that the mixed-voltage capability matches the interface requirements of connected components. Compare against other A42MX09 variants if different speed grades or package types are needed.

Part Context

The A42MX09 belongs to the Actel/Microchip MX FPGA family, known for non-volatile flash-based technology. This series allows for instant-on functionality without external configuration memory. The A42MX09 represents a mid-range density option within the family, balancing gate count with power consumption. It is designed for applications replacing complex discrete logic or small ASICs.

Replacement Considerations

Direct substitutes include other A42MX09 variants with different speed grades or packages, such as A42MX09-VQG100I or A42MX09-FPQG100I. Cross-family replacements like A42MX16 offer higher gate counts but may require design adjustments. Verify pinout compatibility and voltage levels when substituting.
