A42MX09-1PQ160I

Overview

The A42MX09-1PQ160I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 14,000 system gates and 336 Logic Elements (LEs). The device provides 101 I/O pins and operates within a supply voltage range of 4.75V to 5.25V for the core, with support for mixed-voltage I/O at 3.3V or 5.0V. It is housed in a 160-PQFP package (28x28 mm) and supports surface-mount installation. The component is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Single-chip ASIC alternative capability with up to 100% resource utilization and pin locking
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O supplies
• PCI-compliant I/O interface for robust digital communication
• Deterministic, user-controllable timing characteristics

Applications

• Industrial control systems requiring deterministic logic
• Automotive embedded applications compatible with mixed-voltage environments
• Military and aerospace systems utilizing commercial plastic packages
• General-purpose programmable logic replacement for custom ASICs

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard listings often use PQG160 rather than PQ160. Confirm RoHS compliance status, as older revisions may not meet current standards. Check for active Product Change Notices (PCNs) regarding assembly site changes or obsolescence, as this part family has undergone manufacturing transitions. Ensure design-in compatibility with existing PCB footprints for the 160-pin QFP package.

Selection Notes

Select this model when 14,000 system gates are sufficient for the target logic density. Consider the 160-pin package size if board space allows for a 28x28 mm footprint. Verify that the 0°C to +70°C commercial temperature range meets environmental requirements; industrial variants (-40°C to +85°C) exist in the same family but may require different suffixes. Ensure power supply designs accommodate the specified 4.75V to 5.25V core voltage range.

Part Context

This component belongs to the Microchip MX FPGA family, originally developed by Actel before its acquisition by Microsemi and subsequently Microchip. The MX series is designed as a low-power, high-density alternative to ASICs, featuring flash-based non-volatile technology. It shares architectural similarities with other parts like the A42MX09-FPQG100I and A42MX09-1TQ176I, differing primarily in package type and I/O count.

Replacement Considerations

Direct substitutes include other variants in the A42MX09 family such as A42MX09-1PQG160I or A42MX09-1TQ176I, depending on required package and temperature grade. Cross-family replacements from Microchip's PolarFire or IGLOO series may offer modern alternatives but require significant design re-validation due to architectural differences.
