A1020B-PL84I

Field Programmable Gate Array Overview

The A1020B-PL84I is an embedded Field Programmable Gate Array (FPGA) from the ACT™ 1 series, manufactured by Microsemi Corporation. It features a logic density of 2000 equivalent gates organized into 547 Configurable Logic Blocks (CLBs). The device provides 69 general-purpose I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 29.31x29.31 mm. The component supports surface mount installation and functions reliably across an industrial temperature range of -40°C to 85°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing non-volatile flash-based configuration for instant-on operation without external memory requirements.
• High-density logic fabric utilizing 547 CLBs to support complex digital design implementations within a compact footprint.
• Robust I/O interface supporting 69 programmable pins compatible with various logic standards for system integration.

Field Programmable Gate Array Applications

• Industrial control systems requiring reliable programmable logic in harsh environments.
• Telecommunications infrastructure equipment utilizing standard FPGA interfaces.
• Automotive electronics applications demanding wide operating temperature ranges.

Field Programmable Gate Array Procurement Notes

Verify the specific revision level and manufacturing date code upon receipt, as this component has reached end-of-life status. Confirm that the plastic PLCC package condition is free from lead damage or contamination before soldering. Ensure static-sensitive handling procedures are strictly followed during storage and assembly to prevent electrostatic discharge damage to the internal circuitry.

Field Programmable Gate Array Selection Notes

Select this part when a moderate logic capacity of 2000 gates is sufficient for the design requirements. The 84-pin PLCC package is suitable for prototypes or low-volume production where through-hole or specific surface-mount compatibility is needed. Consider the -40°C to 85°C rating for industrial use cases. Evaluate pin count adequacy, as 69 I/Os may limit complexity compared to higher-pin-count variants in the same family.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, which utilizes flash technology for non-volatile configuration. The A1020B variant represents a specific speed grade and temperature extension within the broader A1020 product line. It shares architectural similarities with other members like the A1020A but offers enhanced performance characteristics and extended temperature capabilities defined by the 'B' suffix designation.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Due to the end-of-life status, alternative sourcing requires verification of functional equivalence with newer Microsemi SmartFusion or IGLOO families, though pinouts and logic densities will differ significantly.
