A1425A-1PQG160I

Field Programmable Gate Array Overview

The A1425A-1PQG160I is an ACT3 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 2,500 gate array equivalent gates and 310 Logic Blocks (LABs). The device supports up to 128 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 160-pin PQFP package with dimensions of 28x28 mm. The component supports an industrial operating temperature range from -40°C to +85°C. Key performance metrics include clock-to-output times as low as 9.0 ns for the -1 speed grade and on-chip performance up to 186 MHz.

Field Programmable Gate Array Feature Summary

• ACT3 architecture utilizing PLICE antifuse technology for non-volatile configuration
• Highly predictable performance enabled by automatic place-and-route tools
• Four fast, low-skew clock networks supporting complex timing requirements

Field Programmable Gate Array Applications

• Complex digital logic replacement for legacy TTL and PAL circuits
• High-speed data processing requiring low skew clock distribution
• Industrial control systems requiring wide temperature operation

Field Programmable Gate Array Procurement Notes

This specific part number is marked as obsolete or end-of-life in public distributor records. Verification of current availability requires checking official Microchip discontinuation notices or authorized lifecycle management channels. Buyers should confirm if life-buy programs are active before initiating procurement processes.

Field Programmable Gate Array Selection Notes

Select this component when designing with the ACT3 family requires 2,500 gate capacity and 160-pin surface mount packaging. Ensure design tools support the PLICE programming interface. Verify that the -1 speed grade meets the target system frequency requirements of 186 MHz.

Field Programmable Gate Array Part Context

The A1425A belongs to the Accelerator Series ACT3 family, which succeeded the ACT2 line. This series was designed to replace large numbers of discrete logic components. The '1' suffix indicates the -1 speed grade, representing the highest performance tier within the standard commercial/industrial variants of this density.

Field Programmable Gate Array Replacement Considerations

Microchip recommends migrating to the IGLOO or ProASIC3 families for new designs. No direct pin-compatible replacements exist within the same form factor due to architectural differences.
