A42MX09-FTQ176

Overview

The A42MX09-FTQ176 is a Field Programmable Gate Array (FPGA) belonging to the MX family, manufactured by Microsemi Corporation. It features 14,000 system gates and 684 Configurable Logic Blocks (CLBs). The device supports dual-voltage operation with a core supply of 3V to 3.6V and I/O supplies of 4.5V to 5.5V or 4.75V to 5.25V. It provides 104 user-programmable I/O pins within a 176-pin Thin Quad Flat Package (TQFP) measuring 24x24 mm. The component operates within a temperature range of 0°C to 70°C for commercial applications.

Procurement Notes

Verify RoHS compliance status carefully as older revisions may not meet current environmental standards. Confirm package authenticity against the 176-TQFP specification. Check for recent Product Change Notifications regarding software updates or packaging label modifications. Ensure the supplier provides valid traceability documentation for this discontinued or legacy part number.

Selection Notes

Select this model when 14,000 system gates are sufficient for the design requirements. Verify that the 176-pin TQFP package fits the PCB footprint constraints. Ensure the design utilizes mixed-voltage I/Os compatible with the specified 3.3V or 5.0V levels. Consider the 0°C to 70°C operating range if industrial temperatures are not required.

Part Context
