A1280A-PQG160I

Field Programmable Gate Array Overview

The A1280A-PQG160I is a Field Programmable Gate Array (FPGA) from the Microsemi ACT2 family, manufactured by Microsemi Corporation. It features 8000 equivalent gates and 1232 Configurable Logic Blocks (CLBs). The device supports a maximum clock frequency of 75 MHz and operates on a single 5 V power supply. It is housed in a 160-pin PQFP package with surface mount installation. The component is rated for an industrial temperature range of -40 °C to +85 °C.

Field Programmable Gate Array Feature Summary

• High-density logic capacity utilizing 8000 equivalent gates and 1232 CLBs for complex digital designs.
• ACT2 architecture providing high-speed performance up to 75 MHz with low power consumption.
• Industrial-grade reliability ensuring stable operation across extended temperature ranges.

Field Programmable Gate Array Applications

• Complex digital signal processing systems requiring high gate density.
• Interface bridging between legacy TTL/CMOS components and modern digital systems.
• Custom logic implementation in telecommunications and industrial control equipment.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PQG160I' against official Microsemi documentation to confirm the package type and temperature grade. Confirm RoHS compliance status as older ACT2 variants may not meet current environmental standards. Check for End-of-Life (EOL) or Last-Time-Buy notices, as this component belongs to a mature product line. Ensure design-in support tools are compatible with the ACT2 family before procurement.

Field Programmable Gate Array Selection Notes

Select the A1280A-PQG160I when a design requires approximately 8000 equivalent gates with a 160-pin surface-mount footprint. Compare against the A1280A-1CQ172GC if a ceramic CQFP172 package is preferred instead of plastic PQFP. Consider the A1240A series if military-grade temperature ratings (-55 °C to +125 °C) are required rather than the industrial range. Verify I/O count requirements, as this device offers a fixed number of user I/Os defined by the package.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT2 FPGA family, which was designed to replace multiple discrete TTL and PAL devices. The ACT2 series utilizes PLICE antifuse technology for non-volatile configuration. It represents a mid-range solution within the ACT portfolio, balancing gate count and pin availability for general-purpose programmable logic applications.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. Designers should consult Microsemi's official cross-reference guides or contact technical support for qualified replacements, as ACT2 devices are often superseded by newer families like SmartFusion or IGLOO.
