A1460A-1PQG208I

Field Programmable Gate Array Overview

The A1460A-1PQG208I is a Field Programmable Gate Array (FPGA) from the Microsemi ACT 3 family. It features 6,000 equivalent system gates and 848 Configurable Logic Blocks (CLBs). The device supports up to 130 I/Os within a 208-pin Plastic Quad Flat Package (PQFP). It operates at a maximum clock frequency of 110 MHz with a supply voltage range of 4.5V to 5.5V. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• Non-volatile Flash-based architecture enabling instant-on functionality without external configuration memory.
• Supports in-system programmability for field updates via JTAG or dedicated programming interfaces.
• High-density logic resources provided by 848 CLBs suitable for complex digital control applications.

Field Programmable Gate Array Applications

• Industrial automation controllers requiring deterministic logic processing.
• Telecommunications infrastructure equipment utilizing standard voltage levels.
• Test and measurement instruments needing reconfigurable signal processing paths.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) against the manufacturer's official datasheet. Confirm package integrity as PQFP-208. Check current lifecycle status, as older ACT 3 devices may be subject to discontinuation notices. Ensure compatibility with existing 5V power domains during integration planning.

Field Programmable Gate Array Selection Notes

Select this model when a 5V tolerant FPGA with instant-on capability is required. Compare gate density against the A1415A if lower complexity suffices. Consider the A54SX series for higher performance needs. Verify that the 208-pin PQFP footprint matches the target PCB layout constraints and thermal requirements for the specific application environment.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT 3 Flash FPGA family, which utilizes non-volatile Flash technology. This distinguishes it from volatile SRAM-based FPGAs by eliminating the need for boot configuration chips. The ACT 3 series provides a balance of moderate logic density and high reliability for embedded control systems.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements are limited due to the proprietary Flash architecture. Evaluate the A1460A-1PQG208I itself for updated manufacturing lots. Cross-family migration to ProASIC3 or SmartFusion requires significant schematic and firmware redesign.
