A1280A-PL84I

Field Programmable Gate Array Overview

The A1280A-PL84I is an ACT™ 2 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a logic density of 8,000 system gates organized into 1,232 Configurable Logic Blocks (CLBs). The device provides 140 user I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 176-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. The component supports surface-mount installation and functions reliably across an operating temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 2 architecture providing high-density programmable logic for complex digital designs
• Integrated SRAM-based configuration allowing for rapid prototyping and field updates
• Supports mixed-voltage I/O standards for interfacing with diverse peripheral components

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic logic processing
• Telecommunications infrastructure equipment
• Automotive electronics applications

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PL84I' against official Microsemi documentation to confirm the plastic package type and industrial temperature rating. Confirm RoHS compliance status as older ACT series devices may not meet current environmental directives. Check for active obsolescence notices or last-time-buy dates from authorized distributors before finalizing procurement plans.

Field Programmable Gate Array Selection Notes

Select this component when a moderate gate count of 8,000 is sufficient for the design requirements. Ensure the 176-pin PLCC footprint fits the PCB layout constraints. Compare against the A1280A-PG176C if a ceramic CPGA package or military temperature range is required instead of the plastic PLCC variant.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 2 family of FPGAs, which succeeded the ACT™ 1 series. The ACT™ 2 family offers increased logic density and improved performance characteristics compared to its predecessor. The A1280A model represents the mid-range capacity within this specific generation of SRAM-based programmable logic devices.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements are limited due to the proprietary nature of the ACT™ 2 architecture. Consider the A1280A-PG176C for a ceramic package alternative. For modern equivalents, evaluate Microsemi IGLOO or SmartFusion families, though these require significant schematic and software redesign.
