A1020B-PLG84I

Field Programmable Gate Array Overview

The A1020B-PLG84I is an embedded Field Programmable Gate Array (FPGA) from the Microsemi ACT™ 1 series. It features 547 Configurable Logic Blocks (CLBs) and approximately 2000 equivalent system gates. The device provides 69 user-accessible 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 29.31mm x 29.31mm. 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 high-density logic resources for complex digital designs
• CMOS technology enabling low power consumption and high-speed operation
• Full pin-locking capability allowing deterministic placement of specific logic functions

Field Programmable Gate Array Applications

• Industrial control systems requiring robust programmable logic
• Telecommunications interface circuits
• Automotive electronic subsystems

Field Programmable Gate Array Procurement Notes

Verify the exact suffix designation on the component marking, as variations such as 'C' or 'I' indicate different temperature ratings. Confirm that the PLG84 package matches the target PCB footprint. Check current availability status, as this part may be discontinued or subject to last-time buy restrictions. Ensure compliance with RoHS directives if required by the end application.

Field Programmable Gate Array Selection Notes

Select this model when 547 CLBs are sufficient for the design complexity. Choose the 'I' suffix variant specifically for applications operating below 0°C. Compare against the A1020A series if military qualification is not strictly necessary but similar gate counts are desired. Verify that the 84-pin PLCC package fits the assembly constraints compared to QFP alternatives.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, which serves as a single-chip ASIC alternative. The A1020B variant represents a specific speed grade within the 2000-gate class. It shares architectural similarities with the A1010B but offers higher logic density. The family is known for deterministic timing and full pin locking capabilities.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other ACT™ 1 devices like the A1020A-2PL84I for commercial temperature ranges. Cross-reference with the A10V20B-PL84I if radiation hardening is required. Verify pin compatibility before substituting with different package types.
