A1460A-PQ160I

Field Programmable Gate Array Overview

The A1460A-PQ160I is a Field Programmable Gate Array (FPGA) belonging to the ACT 3 family, manufactured by Microsemi Corporation. It features 848 Configurable Logic Blocks (CLBs) and approximately 6000 equivalent gates. The device operates at a maximum clock frequency of 116.8 MHz with a typical CLB combinatorial delay of 2 ns. It utilizes CMOS technology and supports a nominal supply voltage of 5 V, operating within a range of 4.5 V to 5.5 V. The component is housed in a 160-pin Plastic Quad Flat Package (PQFP) with 168 user I/Os. It is designed for industrial temperature applications, functioning reliably between -40 °C and +85 °C.

Field Programmable Gate Array Feature Summary

• ACT 3 architecture utilizing PLICE antifuse technology for non-volatile configuration storage.

Field Programmable Gate Array Applications

• High-speed digital signal processing systems requiring low-latency logic execution.

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix associated with the PQFP-160 package to ensure timing compliance. Confirm that the procurement source provides documentation regarding the PLICE programming requirements and voltage specifications. Ensure the component meets the required industrial temperature range standards for the intended deployment environment.

Field Programmable Gate Array Selection Notes

Select this model when a moderate gate count FPGA with fast combinatorial delays is required. The 160-pin PQFP package offers a balance of I/O density and physical footprint. Consider the ACT 3 family's single-module sequence functions if complex state machine implementation is necessary for the design.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT 3 series, which succeeded the ACT II family. It shares architectural similarities with other 848-CLB devices like the A1460B but may differ in speed grades or specific I/O configurations. The ACT 3 series was designed to replace multiple TTL packages while providing high-performance programmable logic capabilities.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other variants within the A1460 family, such as the A1460B-PQ160I, provided the speed grade matches the system requirements. Cross-family migration to newer Microchip FPGA architectures requires significant redesign due to differences in logic block structure and I/O standards.
